MR2 Roadster Owners Club

Hi,

Just read the  2"new" engines in 6 months horror story  from a recently new member.

Surely this begs the question that I'm sure I brought up a few years ago...how can we indentify pre and post facelift engines?
Engine Numbers? British Leyland changed the timing on the Metro so many times you had to check the Engine number to confirm the exact timing for the car...

Surely there must be some way, ideally as easy as possible, to tell if the engine is 1999-02, 03to whenever or year of manufacture, that is, apart from the Reg.
I realise it's not the total answer God forbid you have to buy a second hand engine....but it's someway along the line, any information is better than none!

I can't believe Mr T would stuggle to indentify an overbore threatened engine.

While we don't have this information, any second hand engine dealer/ scrapper has members by the shorts. "Just pulled it out an 06 plate pal, lovery car, like new it was, only done 2 thousand miles, owned by a Vicar's wife!" Aye and the rest!!

With the amount of technical brains in this outfit , surely someone can  up with a definitive answer...?  

I''ll shut up now!!  

B AKA Victor Meldrew!!

Maybe we could tie engine numbers to production numbers to get a better idea,i.e if we knew the engine number of a late 02/52 and an early 03/53 and 06/56 or TF300 hopefully we could work out the range of engine numbers if this makes sense?

There was definately a post on Spyderchat about this a few years ago, I remember because my 2001 was on the cusp so it could have gone either way. As it happened, the numbers said old pistons and rings etc.

You could try a search on there or brave a new post.

i have a 52 plate facelift  thats engine number could be of help if someone took the time to collect others and look into it

Quote from: "burty"i have a 52 plate facelift  thats engine number could be of help if someone took the time to collect others and look into it

Without giving the exact number could you list it to the nearest 100?

My MR2 was first registered 14/07/2000 with a chassis/engine no to the nearest 100: JTDFR3207000162**,engine number 1ZZ 05385**.

HI,

Good stuff so far....to be frank, I would have thought it in everyone's interest to have some form of reference.

Maybe the Mods..if they felt it would assist, could set up a folder where motivated members could confirm age, reg date and engine number, This would eventually, with enough response, give us a feel for the issue.yes/no?

if you phrase it correctly, i.e don;t accuse them of killing oue cars with dodgy engines/precats

they may be more helpful than you think

I would say see how this thread goes as this info could be useless if there is no sequential pattern to the numbers or there is no real response with members not giving the info.Why not post your details too and help get the ball rolling.

will look at my old engine later and post up.

All the info is on your log book.  s:D :D s:D

Il look up mine no probs not at home till sunday though, mine has to be one of the first new piston ring design  not many 52 facelifts around to my knowlage its a feb 03

Yeh, the thought crossed my mind as I'm sure the Haynes on the old Metro ran engine numbers and I assume that came from BL.

Anyway.

Reg Date:                           Variant:                             Engine No.

 28.3.2001                  JTDFR32020000338 10         States "No known"?

As stated previously  V5C Form.....has the info.....I'll try and make the time next week to ingratiate myself with Mr T GB, meantime if anyone would like to add details would be helpful....IMHO we should have had some form of reference years ago!

Mike,

Me thinks that would be most helpful, hopefully there are enough replies for a pattern to develop and we can construct a reference. Meantime, I'll have a crack at Mr T next week.

B

For this to be of any use, I need as much information as possible and I hope that all members can get involved, it may or may not show a pattern but if it does then i feel that this is something that we all want to know.

How are you going to tie the engine numbers up with engine production dates? Registration date of the car is useless to you as is 'year' of manufacture, you need the month & year of actual manufacture in the factory.


Anyway, this might help. For all these parts I checked all production years, the dates listed are just the 'important' dates with reference to the particular year I copied & pasted from.

13011 RING SET, PISTON
13011‑22090 1ZZFE..ZZW30, STD (12/1999 - 10/2001) 1 € 142.92
13011‑22150 1ZZFE..ZZW30, STD (11/2001 - 07/2002) 1 € 142.92
The later part - 13011-22150 is then listed for all years through to termination of production. So the piston rings changed from 11/2001.

13101 PISTON SUB-ASSY, W/PIN
13101‑22030 1ZZFE..ZZW30, STD (12/1999 - 11/2001) 4 € 74.82
13101‑22031 1ZZFE..ZZW30, STD (12/2001 - 07/2002) 4 € 74.82
13101 PISTON SUB-ASSY, W/PIN
13101‑22031 1ZZFE..ZZW30, STD (08/2002 - 04/2005) 4 € 74.82
13101‑22032 1ZZFE..ZZW30, STD (05/2005 - 08/2005) 4 € 77.71
The piston changed twice - 13101-22030 is listed for all cars to 11/2001. 13101-22031 is used from 12/2001 through to 04/2005 and finally 13101-22032 was used through the end of production.

13201 ROD SUB-ASSY, CONNECTING
13201‑29038 1ZZFE..ZZW30 (08/2002 - 06/2004) 4 € 121.18
13201‑29176 1ZZFE..ZZW30 (07/2004 - 12/2004) 4 € 123.38
Earlier part runs from beginning of production to 06/2004. Later part runs till 2005 when:

13201 ROD SUB-ASSY, CONNECTING
13201‑09201 1ZZFE..ZZW30, (L) 4 € 149.79
13201‑29038 1ZZFE..ZZW30 4 € 121.18
13201‑29176 1ZZFE..ZZW30, (J) 4 € 123.38
Apparently engines were produced with three possible parts in use..

Also:

17141 MANIFOLD, EXHAUST
17104‑22060 1ZZFE..ZZW30 1 € 1,224.88
17104‑22061 1ZZFE..ZZW30, *115=TOYOTA/00-/Y 1 € 1,224.88
Prior to 2002 only 17104-22060 is listed, in 2002 both are listed and post 2002 only the latter (newer) part is listed.


So .. out of that myriad of changes, which one do you want to gamble was the one that fixed the issue? Is it the rings & pistons which changed in December 2001, or was it the manifold that changed some time in 2002 with no referenced production date?

aaronjb, I assume you used the ToyoDIY site for this info. I don't know how reliable the information is, but I would recommend it as a good starting point if anyone is  looking for info on part numbers, dates, etc.

On a slightly different topic, for those who are looking for interchangability this site now has a "where used" function, so for example the short engine in my car is part number 11400-22060 which is used in

08/1999-06/2005 TOYOTA CELICA ZZT23
05/2000-10/2005 TOYOTA RAV4

No menion of the Avensis, which (for a 2002 model) is part number 11400-0D060, unique to the Avensis

This throws up all kinds of interesting (for some people) data, e.g. one camshaft also fits the Corolla,  Avensis, Celica,& RAV4, whilst the other applies to the last two only. The ABS speed sensor is surprisingly unique to the MR2, whilst the EFi relay (same as the cooling fan) is used all over the place, as you'd expect.

The magic number is 2003,the idea of this is to check if the used engine from an unknown source is from a 2003 onwards as claimed by the seller some of which have cottoned on that everyone wants a 2003 onwards.Surely if we can achieve this then it can only be a good thing and stop people being ripped off buying high mileage prefacelift engines advertised as good low mileage facelift ones,the few participants engine numbers so far seem to indicate a low to high sequence so if we could get some more participants to look at their log book and take part we may be able to nail this.

94,000 at demise.....never used oil or water from one service to the next.

There is info from Toyota stating the date that the change happened was 21July 2005, when the piston and rings were changed. Production stopped in October 2005. This change was to reduce the risk of higher oil consumption. I have been given this info by two people with connections to Toyota.

The change occured from chassis number jtdfr320100074980 until the end of production, last car built being jtdfr320100076411.

Hope this helps!

Clubs reference section says differently,   l viewtopic.php?p=60046#p60046 (http://www.mr2roc.org/phpBB3/viewtopic.php?p=60046#p60046) l   seems a bit odd to change things for a couple of months production.

Hi,

Obviously definite pattern emerging , great but it would help if we had more members details.

Come on Guys/ Girls...this is in everyone's interest¬

I wrote a nice ingratiating  letter to Mr T's Customer Relations last week, no reply as yet.

Incidentally, where is the engine number on the block and can I view it in situ?

B

Oops! had a busy weekend and forgot to check, Must try harder this weekend.

Quote from: "wbarrwebster"Incidentally, where is the engine number on the block and can I view it in situ?
B

The engine number is on the end block just above where the gearbox meets it just below and around the corner from the exhaust manifold.

According to the service book - (Originally) Delivered Aug 2002 engine no 1ZZ10315**

Will have a look at the engine when it's light as it had a replacement short block fitted by Toyota in 2008 - Might have been a reconditioned block though I guess

Heard nothing further to my letter to Mr T.

 Ideally would have been more helpful to have more returns from members, do we have enough information to suggest as a crude rule of thumb
that engine numbers prior to IZZ12613++  are pre facelift or is this too simplistic?

Bear in mind the ideal  requirement is for an easy reference and the ability to purchase a secondhand engine with a WEE bit more confidence than previously!

To be fair, if nobody else replied, surely we're better versed now than prior to the exercise?

B

I'm quite happy with the results showing the engine numbers run in a sequence,which gives enough info to catch out some dubious traders so well worth doing.

Bingo,

Mr T Customer Services just sent me the production year, Vin details and engine numbers on spread sheet starts 2000 to 2006.  
I've only scanned it but can't see a separation on Pre/Post Facelift engine numbers so members will again have to take an educated guess from  when face lift starts.

Would mods confirm that they are happy with this being published, assuming no issues, would one of the whizz kids send me their addy and I will forward as an attachment as I haven't a clue about putting on the system.

Good thread for people buying a used car too...!
I assume registered means the date it got its number plate, not its production date...?

What month approximately in 2003 were the new improved engines produced though?

Colin are you sure its a 'U' at the beginning of yours at not a zero?
Otherwise I was going to say it could be from a different car such as a Corolla maybe?
Then again the Celica numbers seem to correspond!

Quote from: "Tech"Good thread for people buying a used car too...!

Changes happened late 2002 so any 2003 is pretty safe.

When buying a used car is it as simple as seeing whether it is a 5 or 6 speed though? I understand the 6 speeds are the facelift and so I'm guessing that would mean it has the improved engine?

And the facelift bumper - but obviously that could be changed?

Near enough everything from a facelift can, in theory, be retrofitted to a prefacelift car. From the Mechanical (engine, gearbox) to the Body (additional bracing, bumper, vents, lights, etc).

Are you interested in imports as well ?

Don't know if this thread is still active but my V5 shows the car as being registered 27 04 2000 engine number 1ZZ05024** just gone over 91k miles this week.
I may be over simplifying things but it seems to me that if you are looking for a replacement engine then you should be aiming for anything after 1ZZ15

You can probably go earlier than that, two of my confirmed facelift cars had 1zz125*** and 1zz13****

Looks like I've had some early ones then!

Registered ??? 1999  =  1ZZ0434177  (Proper Oil Burner, from a VERY early MR-S)
Registered ??? 2000  =  1ZZ0499415  (On it's way to being an oil burner when scrapped)

And the recon block I am using (very good, no oil loss) = 1ZZ1155444

Pre Face lift
First registered: 31 Oct 2002
Engine no.: 1ZZ10822**
50k. FSH. No oil issues.

Pre face lift
First registered September 2000
Engine no 1zz0528403
70K no oil issues

Sorry to be a bit of a "naysayer" on this but there is very little difference between pre-2002 engines and post-2002 engines in terms of the likelihood of oil control ring failure.  I can also tell you that there are pre-facelift cars with the interim engine upgrade (having just rebuilt the engine on a 2002 pre-FL car which had the supposedly post-FL pistons from the factory).
The newest engine (albeit that I didn't record the engine number) that I have had to rebuild for OCR failure was on a 2005 "Red" special edition car with 70k.
55-plate cars onward seem to be the only ones that are immune to OCR failure.  I can confirm however that service history has a massive impact on the occurrence of OCR failure - if you are checking service history make sure that a service has been carried out at least within every 12 month period AND within 10,000 miles to have the best chance of getting a good engine.  I have yet to see an engine failure (this is only my experience so I cannot say this is a proven fact) on an engine that has this level of service history.

So Matt, are the pistons NOT different then, ie greater number of holes around the piston skirt? Or are they fitted randomly and not in line with the engine number sequences?
Info on actual opened up engines is really useful.

Early pistons have two small holes in the OCR recess.  The next engines have two holes of the same size that are off-centre that overlap the OCR recess and piston skirt.  This change was intended to resolve the oil consumption issue, but it did not.  The latest engines have four larger holes that are also off-set overlapping the OCR recess and piston skirt.  Officially Toyota also made some changes to the block combined with this latest change to increase flow in the oil galleries.
I'm sure that these changes will have been made sequentially (engine number wise) but how that fits in with MR2 production is another matter.  It has kind of been assumed the first changeover took place with the facelift car but my experience suggests it took place before that.  It's rather academic since the first change didn't work anyway!  The second change took place in 2005 but it seems likely that this means that only 55-plate onward cars are sure to have the very latest engine design.

Part of the reason for this post was to be able to spot engine sellers that were selling older high mileage engines and passing them off as newer low mileage units.

74,000 and not checked pre cats yet   s:flame: :flame: s:flame:

Here ya go:

Bought by me 20/02/2013

Reg date:  20/10/2000
Engine:     1ZZ0595657

Engine rebuilt and pre-cats removed by Matt March 2013 at 95,000 miles due to big-end rattle.

2003 03 Roadster facelift registered March 2003.

1ZZ1273492

Definitely facelift pistons.
Precats removed around 35K miles.
Tuned with stage1 cams and lots more.

100K miles saw small oil usage after years of Zero use. 110K miles saw increased oil use when driven consistently aggressively.

Rebuild at 115K miles shows valve guide seals leaking. Blowpast on piston rings, stretched chain beyond tolerance, and a little wear in big end shells. 2005 design pistons in, New big ends, little ends, chain, followers, oil pump, water pump, belt and pulleys.

2005 "chrome" edition with a style bar and stupid chrome ring around the filler flap registered may 2005

Engine number 1ZZ2224894

Serviced every year, previous owner always had and engine flush with the oil change. Only about 25K miles (yes really) so fingers crossed it will outlive me, it's strictly a weekend toy so not expecting issues (famous last words)

FL 22/5/03
Engine number 1ZZ1377491
45K miles
pre-cats done within 1k miles ago.  Previous owner said they looked ok.

Just removed an engine out of a 2001, had a donor engine from a Celica. engine No120005

In my service book its got 1ZZFE 0410** 03 plate 89,000 miles, 5 gears. This was imported from Belgium, so is this a 03 plate and a pre post car??? The first service stamp I have is 19/05/06 with 8965 miles on clock.

FL 08/01/2003
1ZZ11369××
77k
Toyota serviced up until 72k
New Main Cat replaced 04/15
Manifold precat removed last week as precaution.

I think I may have the earliest Face lift on here!

Is this likely to have the better piston rings?

just bought a fixer-upper for very little.

It is a 2,000 but had a recent engine swap.  This engine was sold as first registered in 2006.  Had a peek and the engine number starts with a 2.  Looking at the accumulated list, it would seem that if you want an engine with eight-hole pistons, the engine number needs to begin with a 2.

In Australia first registration can be long after build, so I'm wondering why not build dates?

Here in Oz the 2003 model was released in August, 2002. I have a November 2002 build Facelift SMT Six speed, supposedly first registered Feb, 2004.

So, after reading hundreds and hundreds of posts...I still don't have a clue if my engine is an oil burner or not   s:evil: :evil: s:evil:  
Its a (if I recall correctly) a Nov 2003 car, registered 04/2004.
The engine number is 1ZZ1707##9
Can I please ask just one very simple question: Is this an engine that will use loads of oil...yes or no?   s:scared: :scared: s:scared:  
I've driven about 600 miles since just after I got it, when I filled it to the very top mark on the dipstick, it hasn't dropped a mm yet, not used a drop in over 600 miles of mixed high speed motorway and back road thrashing.
Is this a 'good' engine, or a dodgy one?
then IF i decide to keep it and fit my Toyosport decat manifold, should I expect trouble free miles of fun, as I will have removed the dodgy pre cat material that kills engines?
These are just very basic questions, I'm honestly very surprised that no clear answers can be found, as Toyota are excellent cars and have one of the best customer back-up support and loyalty bases around   s:D :D s:D

It's all down in the main  to how well the car has been serviced in the past, it's not a case of every engine is going to become one

All you can do is regularly check your oil to monitor use by the sound of it no use in 600 miles is a good start

The problem was that many previous owners who maybe used the car as a 2nd neglected the 10,000 mile or 1 year service interval, ran them without checking and either left it too late to intervene and they went bang or sold them on for someone else to inherit a poorly maintained car

There is no harm in replacing the manifold or getting the pre dats removed from the OEM one as a precaution but it's not the pre cats being in place that sets the chain of events off in the main

Most people that have them removed say they are in good condition

So better out than in but don't get too paranoid about it, what service history do you have ?

My 01/03/2005 Roadster's details are as follows.

VIN  JTDFR320600072142

Eng.  1ZZ2092634

According to the paperwork it appears to have been regularly serviced, the previous owner had it serviced once a year (between 5 and 8K) at time of MOT. Now done 55K and all seems good apart from it getting a new clutch on Tuesday.

Quote from: "iPap"There is info from Toyota stating the date that the change happened was 21July 2005, when the piston and rings were changed. Production stopped in October 2005. This change was to reduce the rick of higherbol consumption. I have been given this info by two people with connections to Toyota.

The change occured from chassis number jtdfr320100074980 until the end of production, last car built being jtdfr320100076411.

Hope this helps!

Clubs reference section says differently,   l viewtopic.php?p=60046#p60046 (http://www.mr2roc.org/phpBB3/viewtopic.php?p=60046#p60046) l   seems a bit odd to change things for a couple of months production.

According to the Parts book the pistons changed on this date and VIN, but not rings.

Parts book possibly refers to when the upgraded parts entered manufacture, i.e May 2005 with older stock being used up by July when they started being used in engine assembly?

So, changed a few times, and whether any of them totally fixed the issue....??
