1zz help/advice

I'd be pretty gutted going from 177bhp turbo to 190hp (best case scenario) 2zz to be honest. It's the torque. It's all about the torque.

Rebuild 1zz, stick your turbo back on. Happy days.

Another vote for rebuilding the engine you've got. Inspect the turbo when it's off the car and make sure it's healthy.

What could have affected the turbo with the problem I have ?

Carolyn · September 1, 2016, 13:47

When a turbo starts to break up bits can end up in the engine. I'm not saying this is what happened - but it could be that the turbo is the source of your problems.
I've seen other engines scrapped this way.
The way it happens, turbo oil seals start leaking, then play develops in the turbo's bearings then turbo blades start to hit the housing....
Not trying to put you off, just saying 'check and be sure'. It's not easy when you have to entrust the work to others, I know, but it would be worth visiting your re-builder and having a good look, once it's in pieces. No decent mechanic would object to that.
I'd certainly want to know the cause of the failure.

Just a thought bouncing off another thread if it helps for considering costs..- the dutch appear to be selling a shortblock for £1130.

"Originating from the Toyota Exchange Programme, completely overhauled engine block with new pistons, bearings etc. Comes with: - New dipstick with larger display (15301-0D011) - Complete gasket set (04111-22062) - 6 Liter Toyota for Life Coolant - 5 liter Toyota 10W40 Engine Oil - Oil filter (90915-YZZJ1)"

I like the bit about new dipstick with larger display... might have look at buying that separate!

Hi all , back for some more info .............

what would constitute a nice stock rebuild of the 1zz........??

I know the shopping list could be long , but look forward to your suggestions ..........

cheers

First... select a good engine specialist. Once the engine is apart it's about measuring and inspecting to decide what is required (which is where honest expertise is needed). The basics are clean pistons, new rings, hone cylinders, valve seals, lap valves, change rod bearings...). Then you might go for, upgraded pistons, new timing chain and guides. You will also need new gaskets and head bolts. I favour popping in a new thermostat ('cos it's a pig of a job in the car) and consider a new water pump.
Edit: IF it has ingested bits of turbo (I hope not), the engine might not be worth rebuilding. Stop there and consider alternatives, such as rebuilding a used engine

Hi all emergency help please

Bought a low miles 2004 engine , my engine is out but the newer engine has different oil cooling hoses etc I'm being told .....

Where do we connect them ...!!!

Carolyn · October 5, 2016, 14:04

If it's out of a Roadster, there aren't any oil cooling hoses. A 2004 will go right in. I know 'cos I've got two in two PFL cars. All the connections and hoses are the same, only an MR S will not have the connection for the post-cat sensor. If it's a 1ZZ FE out of a different car, quite a few things are different, like the intake manifold and you'll have to swap bits over.
Before you put it in, check that the oil was clean.

paul.mcgrath · October 5, 2016, 14:15

I have an MRS ... can it go in ??

Carolyn · October 5, 2016, 14:36

Oh yes . One of mine is an MRS. Just ignore the extra O2 connector. The ecu will be fine.

paul.mcgrath · October 5, 2016, 15:37

Hi I've got two extra cooling pipes from the oil filter that I need to know where to connect to ??

The Apexi management will be ok aswell ??

Thanks for your help

Carolyn · October 5, 2016, 15:47

It's just the electrical connection for the main cat - which an MR S doesn't have. The Apexi might need a tweek - I've no experience of that. I doubt it though, as you're already set up to run without a post-cat sensor (unless that's been changed). Any doubts -ask Schnazzle 'cos he's a bit of a whizz at the management stuff.
I'm sure you'll be fine. As I said, I've put an 04 Euro engine in an MRS and it's fine. Didn't even change the loom.

paul.mcgrath · October 5, 2016, 16:00

Thanks again

And the 2 oil cooling pipes , where do we connect them ? My MRS engine hasn't got them ..

Sorry I'm relaying this all to the mechanic

Carolyn · October 5, 2016, 16:14

Are you talking about circulation for a turbo? There is no oil cooler on a roadster. If you have an engine with cooling pipes, it's either modified or not out of a Roadster. If it IS out of a Roadster and has cooling pipes, you can either install an oil cooler or remove the pipes and block off the ports. If it's not a Roadster engine, there could be a lot of stuff that is different. I know 1ZZ FE engines out of front wheel drive cars are set up quite differently, and you'll have to swap over quite a lot off stuff from your old engine. You'll have to put them side by side and compare. I do know that the intake manifold is different, for starters. Then there might be a power-steering pump which the roadster doesn't use (that would be two extra pipes) - that would have to be replaced with your idler pulley.
Others with wider experience of 1ZZ variants will have to help here, I'm afraid.
ARE you SURE your new engine is out of a roadster? Or is it out of a Corolla or Celica, or Avensis?

paul.mcgrath · October 5, 2016, 16:34

I've asked the question if it's out of a roadster again , it was advertised as a roadster engine ....

Jrichards20 · October 5, 2016, 16:37

Who did you take it for to the rebuilt? Surely they would know/

Carolyn · October 5, 2016, 16:46

Hmmm... Well - all is not lost. The basic engine is the same. You need to put them side-by-side and make the new one look like your old one. If it's out of a Roadster, they will be the same. If it's not, keep swapping till they are the same. If the intake manifold is different -that's a big give-away. All you have to do, however, is swap them. If they ARE different engines, you will want to swap the loom over too. Oh, I think the valve covers are also different, with the filler cap in a slightly different position. It can all be swapped over.
You can't do this by remote, you need to go to your mechanic and look at it.
Not all mechanics will know, that doesn't mean he's a bad mechanic, we all have gaps in our knowledge. However, he should be able to see if it's a different set-up.

paul.mcgrath · October 5, 2016, 17:14

Ok from a picture I've seen the new engine has 2 pipes just above oil filter coming out .....

The old engine from the MRS has one pipe ......

I could email pics if that's allowed ..... I'm away at the moment and posting from my phone

Thanks

Carolyn · October 5, 2016, 17:19

You're MRS has a turbo?

jonbill · October 5, 2016, 17:35

On my car, there is coolant water pipes to and from the oil filter housing - they go to the water pipe that goes around the back of the head. I never figured out what they do, they can't be cooling or heating the oil.
I suspect that you can probably blank them.
I'll see if I have a pic

jonbill · October 5, 2016, 17:37

This is it - pic from underneath during assembly - is this the bit you're talking about?

jonbill · October 5, 2016, 17:40

And I think these two are the hoses joining it to the cooling system (but I could be wrong!)

Carolyn · October 5, 2016, 17:51

Just looked under my Blue car. Not disturbed the engine on that one. It has an 04 facelift engine and it has the same two pipes. Can't see where they go as they disappear behind the inlet manifold. The MRS doesn't have even one. I'll check my other engine tomorrow.
Any one rebuilt an 04 engine?
Looking at Jonbill's pic it's a water-cooled oil cooler. At least you can see where they go. Anything that helps with the cooling can't be bad.
Just felt around under my silver car - that's the MRS with an early 04 engine in it. It has the same plumbing. Definitely a water jacket oil cooler. Any extra hose on your MRS must be a turbo oil-feed? In which case you'll need to swap over the sandwich plate and the oil pan for the oil return. Never noticed the oil cooler as it went in as a lump.
Our Peugeot diesels have a similar type of oil cooler.
Stop Press: Just took a pic of the MRS oil filter housing. It's quite different as you can see. There is also no hub nut inside the housing, which probably retains the cooler.

You live and learn!
