ray007 Posted November 30, 2012 Share Posted November 30, 2012 (edited) Hi all Having problems since having the head off and new gaskets fitted all round, including head gasket, inlet and turboanifold gaskets, valve stem seals, crank seals etc etc Now the car starts but there's NO BOOST at all, when revved makes a weird sound and there's some white smoke from the exhaust I tried the TTC mod but that didnt make any difference Video: any advice would be much appreciated Edited November 30, 2012 by ray007 (see edit history) Quote Link to comment Share on other sites More sharing options...

Nic Posted November 30, 2012 Share Posted November 30, 2012 Sounds like the timing is out, check the timing belt is fitted correctly, check the timing marks on the camshaft pulley and cam pulleys are all aligned correctly. http://img841.imageshack.us/img841/3568/picture1tk.jpg Quote Link to comment Share on other sites More sharing options...
safcdixon Posted November 30, 2012 Share Posted November 30, 2012 Have you checked the turbines too make sure they are free? that whineing noise doesnt sound good, its sounds as if something is fouled as it seems to get louder on higher revs, White smoke would indidcate moisture, so maybe you have an airleak within the turbo system, may not be the easiest thing to do but maybe strip down the turbo side and rebuild it again its easy to miss one hose off Quote Link to comment Share on other sites More sharing options...
ray007 Posted November 30, 2012 Author Share Posted November 30, 2012 Just to mention the turbos seemed in good condition when taken apart. And checked all the hoses/vacuums etc about 10 times yesterday to make sure. Can't find any visual faults or air leaks Also must mention the car was very cold when started and sounded a little lumpy in the video, however usually does sound sweet on idle, can only hear noises when revved really Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted December 1, 2012 Share Posted December 1, 2012 Agree with Nic's diagnosis. I have the timing half a tooth out on one of my Calibra's once, and it had me stumped for ages! Quote Link to comment Share on other sites More sharing options...
ray007 Posted December 3, 2012 Author Share Posted December 3, 2012 Thanks guys So I guess my next step to get the timing checked I've got a bad feeling it's out now mentioned as I did have aftermarket cam gears/pulleys installed on the stock cams (jus to look nice) and they might be out of place so I gues cam convers coming off again :-( Any other suggestions would be much appreciate and Thanks for your input guys Quote Link to comment Share on other sites More sharing options...

ray007 Posted December 4, 2012 Author Share Posted December 4, 2012 Wot I mean is, because the timing marks look ok, is it possible whilst I had the cam pulleys installed they Werner correctly aligned with the cams if you know what I mean? Plus cams have been out maybe not reinstalled correctly? Quote Link to comment Share on other sites More sharing options...
HadeS Posted December 4, 2012 Share Posted December 4, 2012 Who your coil packs look like? Are they all in good condition? Quote Link to comment Share on other sites More sharing options...
little num Posted December 4, 2012 Share Posted December 4, 2012 The white smoke looks like burning oil so id say foocked turbo, looks and sounds like the mk3 i had with a blown rear turbo. Check the exhaust for oil and check the intercooler pipes to see if they have oil in, if you dont find oil in any of the pipes or exhaust tip then it may be more serious. I doubt the cam pullys can be fitted wrong due to having a locking pin that fits in the back and thats on both inlet and exhaust, they may have turned but that wouldnt cause white smoke out the exhaust.

Swampy442 Posted December 4, 2012 Share Posted December 4, 2012 No boost, lots of smoke, gotta agree with James here, looks like turbo(s) to me too Quote Link to comment Share on other sites More sharing options...
ray007 Posted December 5, 2012 Author Share Posted December 5, 2012 Who your coil packs look like? Are they all in good condition? Whilst servicing i changed coil pack for lower mileaged good running ones, plus new coil pack clips The white smoke looks like burning oil so id say foocked turbo, looks and sounds like the mk3 i had with a blown rear turbo. Check the exhaust for oil and check the intercooler pipes to see if they have oil in, if you dont find oil in any of the pipes or exhaust tip then it may be more serious.

No boost, lots of smoke, gotta agree with James here, looks like turbo(s) to me too Can't work it out as when turbos were removed they seemed in good condition and there was hardly any/minimum play. Is it possible a turbo was damaged whilst installation? And there is no oil in the intercooler/boost pipes Quote Link to comment Share on other sites More sharing options...
ray007 Posted December 5, 2012 Author Share Posted December 5, 2012 (edited) Just had another thought.. The turbo oil return line (I think from 1st turbo) was butchered in the process of removal so was replaced with custom hose Is it possible that this hose is maybe smaller or not flowing good causing excess oil burning in turbo?

Yeah that will certainly cause problems, the oil will back up in the drain, flooding the bearing chamber. By doing that it may well wreck the oil seals anyway.

By doing that it may well wreck the oil seals anyway. Agreed, if you don't havea free return to the sump then you over pressure the turbo oil bearing and it blows its oil seal Causing burning oil smoke, however you'd still get boost The engine sounds like its firing correctly and it's timing is within limits, I'd say its more likely the wastegate is bypassing or something, it's unlikely that your turbo(s) would suddenly fail just because they've been removed then put back on, if before they worked fine Possibly human error somewhere?

Sounds a little reassuring - as engine and turbos were running fine before taking apart. I strongly believe its human error but it worries me what damage could have been done and where the problem lies Quote Link to comment Share on other sites More sharing options...
little num Posted December 5, 2012 Share Posted December 5, 2012 if it was the oil return no draining back fast enought then that would cause smoke BUT wouldnt cause no boost. Id put money on blown tubby. Quote Link to comment Share on other sites More sharing options...

Id put money on blown tubby. I hope your wrong but I know you're experienced with supra's... If one turbo is blown will the other not still boost a little?

TubbyTwo Posted December 5, 2012 Share Posted December 5, 2012 if the first turbo was blown it would probably have a knock on effect on the 2nd turbo. Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 6, 2012 Share Posted December 6, 2012 And I the compression is good where do I go from there? its just to check that the head gasket was correctly done being white smoke like that could well be water from a blown gasket, no boost though ? have you taken off the intercooler piping and put your hand there to see if they are blowing anything at all when reving?
