MR2 Roadster Owners Club

Had a small problem with some white/blue smoke comming from the exhaust when stationary the other day. I stopped at the traffic lights when the smoke started to come, out not a lot but enough to get me worried. When I drove off it stopped. The car is driving fine no problems at all. I has been using a bit of oil and is due a oil change. Happened before after a big run abit of smoke then it stoped.

The car was fitted with a TTET last March and the SP stage II went in in January and no changes since then. Its a 2004 and had no problems with the precats they wern't in for long. Any thoughts ?

So its never happened since turboin the car? what was the weather conditons like there recently and was early in the day?

Never had any problems before going turbo. Funny enough both time were when it has been quite cold and raining a bit. Last time was after a 10 mile drive and it was in the evening.

Personally i wouldnt worry! my 2 always chucked out white smoke with the TTE, not as as much now as it did, now its SP'd,  maybe because its a different exhaust, but i noticed its worse depending on atmospheric conditions, ie cool temps and moisture, etc, just keep an eye out on it! if no noises or performance issues have arisen, then keep having fun   s:) :) s:)

Mine chucks out loads of smoke for the first 10 mins now it's de-catted. I'm glad it's happening to others   s:) :) s:)

i've seen this on TTET's as well and iirc its been reported before on here. Just out of interest how's the crank case breather setup?

Quote from: "kanujunkie"..... iirc its been reported before on here....

DavidM reported it over a year ago and it was discussed as condensation. Mine has an oily smell to it and looks more like smoke.

Good to know it's not just me then. The engine sounds thesame as it always did a bit ticky but that is probably down to the 0w-40 oil that I am using. Does anyone know why it would smoke a bit only happens for me after I have been driving for a bit the stop at lights with the engine going ?

never understood why TTE say you need to put 0W40 in, its got all the consistency of water

Edited.... it stopping briefly but is smoking again

I put 5w40 in mine this time, I thought I saw smoke the other night when I looked in my mirror and the cars headlights behind mine appeared to be shining through smoke - maybe someone can have a look for me on the drive on Saturday.

I'm sure you'll be able to get one of us to look at your rear, Liz..

Anyone want to look at my rear....   s:? :? s:?  

It's a bit smelly though   s:oops: :oops: s:oops:

I spoke to Matt @ SP today and he said that his car does the same and it is normal for the car to do this. Even though I spoke to him I am still a bit worried as it was smoking twice today. I had a oil change done last week and was hoping that it would have sorted the problem out. The engine bay does seam quite hot but it probably me just being over causious. I will just have to measure the oil consumption and see if there is a issue there.   s:? :? s:?    s:? :? s:?

Hmmm, mine is doing it again. I think I'll join you on the oil consumption monitoring   s:( :( s:(

i have noticed smoke from my car on occasions and it did worry me originally but the car does not use any oil and has not made any noises other than the norm , so it appears to be a trait of the tte turbo possibly  due to the 0w-40 oil , time will tell .

Well my fan isnt even operating and neither is SP's, so i wouldnt worry too much about heat! im not!  s:wink: :wink: s:wink:

The fan on mine has only been on twice since going to stage II in January  I am not really worried just it's getting quite hot in there. I have been thinking about some extra cooling and possibly aquamist.

chris can you not get your fan fixed under the tte warranty , it may not cause you any problems but i would want my car to be in full working order   s:) :) s:)

The fan is controlled with the TTE ECU but with the stage II it is replaced with the SP ECU so is now hooked up to the radiator at the front of the car which isn't on to much.

Yeah it will get fixed Phil, when i get work done on the car next at SP, for some reason they got Simon's fan working fine but mine didnt work it was doing the opposite to what it should be doing but they ran out of time to troubleshoot it, anyway Matt will sort it!  s:wink: :wink: s:wink:

Simon why dont you start to upgrade ur 2 setup when you do the cooling, then you can do more power at the same time  s8) 8) s8)

i thought the turbo fan was tripped by the sensor on the boot lid that measures the temp in the engine bay , if it is linked to the fan on the radiator at the front of the car which also benifits from cool air as you drive that would explain why it does not come on as often , my fan comes on a lot so this may be a teathing problem that sp needs to sort out with the sp240   s:? :? s:?

As far as i see it because the TTE piggyback is made redundant so is the programing that operates the fan is lost, hence SP using the radiator fan to work with the engine bay fan but to behonest the TTE fan comes on far too much, unnessesary at times, so really with the SP way you should in theory be getting best of both worlds!

i have noticed that my fan does come on a lot but then the engine bay is very hot but i have also noticed that the radiator fan that is positioned at the front of the car and benifiting from cool air whilst driving hardly ever comes on. the turbo fan and radiator fan are operating under different conditions .

Just had the car out for a good spanking and the smoke started to come out the hood so I stopped and had a look and there was smoke comming from one of the hoses that goes into the turbo. It is covered in heat wrap which has nearly all come off. I have some pics so hopefully it is a easy change the pipe and heat wrap and the car is sorted.

I have sent the pics to Matt @ SP so he can have a look. Must give him a buzz now.

So much for it being normal eh?

That looks (from what I can tell) to be a coolant feed hose I think - so the smoke from there would be steam..

Although there appears to be some black stuff splattered around that's more likely to be oil, so perhaps that's leaking too..


Anyway - as people have said over on SC, smoke (from anywhere, including the exhaust) is not normal.

[edit] Ah, you said you think it's the oil return over at SC - is this a shot looking upward from under the car?

If so that's highly likely - which would explain the smoke if it's backed up and no longer emptying properly..

Turns out it the water return line so that rules that idea out. I am going to get the heat wrap replaced and have some one look at the oil lines on the Turbo itself.

umm! that heat wrap has seen better days, wonder why its got that worn out looking!

I was getting a bit worn before I went stage II and after that the extra heat in the engine bay has just melted it. I am taking it to my local shop that does a lot of work of evo's for them to have a look at the oil return and the heat wrap hopefully they can shed some light on the whole thing.

I had a friend look at the car and they couldn't see anything wrong with it except the heat but he seamed to think that the smoke is white and not blue as I thought and there is a very funny smell from the exhaust and engine bay. The problem seams tobe getting worse as it is smoking all the time now itsits idleing for more than 30secs. I am confused   s:? :? s:?    s:? :? s:?

I know you say you have monitored the oil consumption but have you monitored the coolant consumption?  Perhaps it is time for a compression and leak down test of the cylinders.  s:? :? s:?

Quote from: "simonmr2".....and there is a very funny smell from the exhaust and engine bay....

Is the funny smell just because there is no cat?

Quote from: "kanujunkie".....Just out of interest how's the crank case breather setup?

I've just had a look at the installation manual and I can't see any real difference from the stock setup. The engine breather hose is shortened a little but that's the only modification. My (very limited) understanding though is that this is after idling and there is very little blow by volume at idle which would rule out the PCV setup.

Had the car up a my local garage who do a lot of work on evo's etc and they have diagnosed the problem as a leaking seal in the turbo letting oil get into the exhaust causing the smoke. The car is going into them next week for them to do some heatwraping and then they will have a look at the turbo to double check this.

They say they have seen this problem before on other cars such as subaru's and evos because of the heat created under the hood.

Interesting! update, soon as!

Keep us posted. I suspect I might have the same problem.

The heat wrap on my car is knackered and I think this has had a major effect on this and with the severe heat the seals have just sprung a leak. Hopefully this is what it is as it is a simple job for these guys to do. It realy has been annoying me as it is really embarasing.

Haven't had any oil problems still full after 1000 miles of motoring so again I am confused !!

I'd be impressed if you could make turbo bearing seals (I think the TTE is plain bearing?) leak enough to be noticable on the dipstick..

Even when I grenaded a turbo totally it didn't leak that much out the exhaust side.. most of it came out the intake side, actually (all over the firewall of the car  s:oops: :oops: s:oops:  )

It's only when I'm sat idling for any length of time that I get blue smoke. And I'm talking LOTS of it. It's totally embarressing coupled with the loud clutch squeek I have   s:oops: :oops: s:oops:  

I've had oil in the tail pipes, inlet seems fine at the throttle body - no signs of oil. Coolant levels haven't budged at all! No contamination in the coolant in the rad. O2 sensors in exhaust manifold look fine. It must be leaking in my turbo .... exhaust side. This could be due to blocked oil drain from the turbo, pressure in crank case or oil seal, I'm not sure which.

It's definately got worse since I decatted. Loss of back pressure drawing oil out of the turbo perhaps?

Matt that is exactly what I have been getting when I leaveit in next week and they have a look at the turbo hopefully we will have a answer to what is the problem.

The car is in now and they are going to look at the turbo to see if that is still working properly. The waiting game beging now. Might be able to claim on waranty.

Quote from: "simonmr2"Might be able to claim on waranty.

Might wanna change your signature 'SP Turbo Stage **'    s:wink: :wink: s:wink:

Just of the phone about my car and it's not good news they say that the turbo is knackered and will either need replacing or referbed. They say that there is loads of discharge round the turbo and there is to much play in the turbo shaft. I have phoned Matt and a awaiting his return call. Total pita as I really need my car for work.

The turbo only went on in March 06 soit seams a short time to go boom but hope between SP & ECC they will be able to sort the problem out.

Do you happen to know (did they say?) whether the turbo is a ball-bearing CHS or plain thrust bearing CHS?

If it's the former then refurb is unlikely (I was lead to believe, by a Garrett dealer, impossible) - if it's the latter then refurb is easy, but upgrade to a 360deg. thrust bearing if it doesn't already have one as they're much stronger.

Also - see if you can find out the spec of the turbo and the boost pressure the upgrade runs it at.. I'd love to see how hard the envelope on these is being pushed - dying in a year suggests very hard indeed.

I am going up shortly to collect the car untill I can talk to SP to see if they are going to sort it out through the waranty with TTE (dont mention stage II) I will find out. The car is used to the max every day I dont hold back.

I had a problem with my turbo or i suppose you could say still have, we are talking about a year and a half ago when i was having work done on the 2 and rouge mentioned that they had found some damage to the turbo, to do with the blades! at some stage they got damaged but *touch wood* it hasnt effected the running and performance of the car!

But i carnt say when the turbo would have got damaged?! so i wonder if theres an issue there!

That is the same problem that ECC say is wrong with my turbo and that there is a lot of movement in the rotors. Having spoke to Matt he has a other theory about the seals and the vacume when the car is idleing as there is now 3 cases of the same problem. He is collecting info on it and is going to contact TTE to se what they have to say about it.

Also the Garrett turbo could be reconditioned if it is bust but you would be looking at £500ish for this. I really need TTE to sort out the problem and get my car running back to 100%.

Quote from: "simonmr2"Also the Garrett turbo could be reconditioned if it is bust but you would be looking at £500ish for this.

Er.. you can buy a whole new unit for £500!

I would of thought for that money you could upgrade for a new and better one? *edit, i see aaron best me to it*

Did the guys who looked at it or did Matt say anything to you about long term use?

Surely you're warrenty is with SP and not with TTE?

The werrenty for the turbo is with TTE and not SP as they only fit it bit I believe that they will sort the werrenty claimout if needed. Long term who knows all I know is that my problem has been getting worse over the last 3 months.

I sent Matt a clip of video of the smoke and am about to sent him a email with the exact detials of my car mileage since turbo etc so when he contacts TTE he has all the info.

Oh I was under the impression that one of the reasons the whole thing was so expensive was that SP provided a warrenty..

forgive me northern chums.

as you know i have problems with people saying brought instead of bought.

but this one i have to correct.

the word is WARRANTY !!!! i only point it out alex, as the link you posted dunt wurk.

when you change the spelling to the correct one, its actually a very good site.  i put my details in and its offered me one for about 22 quid per month.

chins up big guys.

E

Is there a co-incidence that the Turbos are having problems which have had the 240 (225) conversion?  Would TTE cover them in that case?

Incidentally I noticed my heat wrap starting to go on the car in the same place as pictured above...I put some wire around it in the hope that it will keep it in place.

I've not had the SP240 and I'm definately having problems

My car is the only SP 240 that is having problems the other 2 people that are having problems are standard TTET's. I am sure that TTE/SP will sort it out in the end. When I do get it sorted I willbe looking for some serious heat wrating as the stuff on atm is all starting to go now.

Quote from: "aaronjb"Also - see if you can find out the spec of the turbo and the boost pressure the upgrade runs it at.. I'd love to see how hard the envelope on these is being pushed - dying in a year suggests very hard indeed.

I had a quick look at the 'standard' TTE conversion done to Liz's Roadster a few weeks back. Comparing it to the PE kit, the compressor housing does look to be bigger and so probably more efficient at compressing air than the PE at the expense (possibly) of a little more lag.

As for boost levels and power - with my PE setup, 7psi gives 235bhp after a recent remap at Perfect Touch - but going to higher boost levels just gives you more mid-range torque but the same peak power - probably as the turbo flow is max'ed out anyway near redline.

Driving @ 7psi the car feels less laggy and more progressive than at 10psi - but at 10psi there is a lot more mid-range torque.

I'm surprised though to hear that a few of the Garrett turbo based TTE kits are experiencing early life failures though. My PE kit has probably 60k miles on it and at my last check back in May was still in great condition.

Ben.

I've been having a lot of embarrassing commutes on the north circular, stuck in traffic, chucking out blue smoke. I decided to contact TTE direct to get some information on this problem. Here is my email to them and also the response.....

I have an MR2 Roadster TTE turbo (turbo conversion done March 06 by Silverstone Performance). I have noticed a lot of blue smoke from the exhaust during periods of engine idle. I have been informed that TTE know about this issue and it is due to the oil drain pipe from the turbo and that a revised part was shipped with the TTE turbo kits at some point after my installation. The part numbers I am refering to on my installation are....
14-4 pipe, oil runback AM869-79000
14-5 Hose, connection to oil pan AM869-80000
Please could you confirm that these parts have been revised and tell me how to get hold of the new parts?
Thanks for your help

Hello Matt,
thank you for your inquiry.
The mentioned parts are revised to solve this problem. Please be so kind and contact Silverstone to order these parts. Matt Lee ( e matt@silverstoneperformance.co.uk e )  is your contact person.
If you have any further questions please do not hesitate to contact me again.
 
Kind regards,
Toyota Motorsport GmbH

So, finally this can get fixed. It's totally been ruining my enjoyment of this car.

Brfore my car went to the big scrap yard in the sky I was talking to Matt @ SP and was going to get pics of the oil return line and he is aware that it was updated to help the flow of the oil. I think that you got the car off another member who was the second TTET fitted at SP so it would be the early oil return line. Give Matt a bell he will sort it out.

Last time I was at SP, Matt looked at my oil return and confirmed it looked like I had the early part. I'm just waiting for SP to get the revised parts.

Fixed   s:D :D s:D  

SP fitted the revised oil drain on Friday for me and I'm totally chuffed to say that I no longer smoke at idle! WoooHooo   s:) :) s:)  

SP also managed to get TTE to foot the bill   s:) :) s:)  

Very happy with SP for everything they have done for me on this one   s8) 8) s8)
