ksbkrew Posted May 22, 2011 Share Posted May 22, 2011 Hello i've got a problem with mine supra, it's a uk one, with OBX TO4s single, tial wastegate 46mm , ebay manifold, at cold start and during 10minutes while rolling, my car smokes a lot with a blue smoke. and after when hard pulling it's doing it again before changing for a single , there weren't any problem. i'm asking myself one question , is my oil feed line and return line, maybe too inclinate? i post you pics to have your opinion http://img836.imageshack.us/img836/7439/img7755g.jpg http://img835.imageshack.us/img835/3092/img7792h.jpg or do you have any ideas? the probleme is that if the lines are too much inclinates it would be hard to change it without my return line touch the manifold, or can i do it without problem? sorry for my english, i'm french and try to best my best to be comprehensible Many thanks Tom Quote Link to comment Share on other sites More sharing options...
aman00123 Posted May 22, 2011 Share Posted May 22, 2011 I thought blue smoke meant the oil seals were gone on the turbo? Did you get the kit brand new bud? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 22, 2011 Share Posted May 22, 2011 As abovem is it a new turbo or second hand? Is there a restrictor in the oil feed line? Quote Link to comment Share on other sites More sharing options...

johnny g Posted May 22, 2011 Share Posted May 22, 2011 Could it be blow-by from under-sized PCV breather? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 22, 2011 Share Posted May 22, 2011 Sounds like turbo shaft seals. Could possibly be valve stem seals, but it would almost certainly have shown this before the turbo change. Quote Link to comment Share on other sites More sharing options...
aman00123 Posted May 22, 2011 Share Posted May 22, 2011 He says before the single conversion it was fine so my money is on the turbo oil seals - either a 2nd hand turbo which already had blown seals or some crap got in and has buggered your seals after the conversion Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted May 22, 2011 Author Share Posted May 22, 2011 the turbo is brand new, no second hand, done 200 miles with it and before first start , i've started the engine without the ignition to fill it with oil Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 22, 2011 Share Posted May 22, 2011 the turbo is brand new, no second hand, done 200 miles with it and before first start , i've started the engine without the ignition to fill it with oil Ask them in writing if the turbo is made in the USA or the far east (probably China?), and see what they say, I am sorry to say I would think your issues are a turbo one.

Wez Posted May 22, 2011 Share Posted May 22, 2011 Sounds like turbo seals. Just curious, what fueling mods are done, ie ECU or piggyback, injectors and pump etc. Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted May 22, 2011 Author Share Posted May 22, 2011 stock UK pump and 550cc injectors. Piggyback ecu (mapecu) Aem wide band at full boost it gives me 11.4-11.5 Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted May 22, 2011 Author Share Posted May 22, 2011 i 've look my return line under the turbo, and it seems to be full of oil like if the oil is sitting at this location. if the return is too much inclinated , can this cause an oil sitting in the turbo and after it goes into the intake and exhaust?

aman00123 Posted May 22, 2011 Share Posted May 22, 2011 Not sure on the angle of the pipes but the reason some of us think it is the turbo oil seals is that it doesn't affect performance so it will still pull strong but it means oil is leaking into your turbo and burning - causing the blue smoke - the problems are that you will lose oil a lot more quickly than you should and may run dry if you don't keep an eye on it Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted May 23, 2011 Share Posted May 23, 2011 I'm not 100% clued up on the exact requirements needed for a single turbo but i have non stopped been looking into it for months now but with the list of stock UK pump and 550cc injectors. Piggyback ecu (mapecu) Aem wide band Doesn't sound efficient enough anyway? Surely u have to have uprated fuel pump, bigger injectors than 550cc and full management to support this? Dont want to under fuel and melt a piston or sumin... Quote Link to comment Share on other sites More sharing options...

Nic Posted May 23, 2011 Share Posted May 23, 2011 Is it a genuine Garrett T04S? Did you buy from a Garrett dealer or off Ebay? There are a lot of cheap quality Chinese knock off turbos around now. Quote Link to comment Share on other sites More sharing options...
