turbo seals/ exhaust stem seals

Recommended Posts

hi got a bit of an issue just brought the car out today first time since November and its chucking out white/blue smoke. defiantly oil. it seem to chuck it out while pottering around light throttle and on overrun. under load it doesn't seem bad at all but if you lift off and wait say 7-8 seconds you get a big cloud.

 

so got home pulled the plugs out all fine nice and clean no sign of oil. did a compression test and all mint. 11-12 bar.

 

so has any one had a similar problem, just thinking its probably a turbo. exhaust stems seals possibly. im not to common with supras but the first turbo does seem a bit noisy. i cant remember what the car was like before plus it was the day i bought it so i was just getting used to it.

 

car is a bpu 1996 rz tt6 80k on the clock

 

also what sort of oil pressure are these running. 8-9 bar when cold light throttle. when warm getting 7 bar at 3k that normal. just seems a bit high to me dont know if a prv is stuck or something

 

cheers for your help antno

Hi im having the same problem with mine but mines a uk car iv found a couple of places near me in sheffield that will do it, one of them suggested that if i was to let everyone know on the forum that he would sort it owt cheap thats fully rebuilt uk spec turbos for £150 each turbo but hes going to let me know when he can get hold of the parts for it the other is ken the number is 07852201375 seems a real nice guy he specialises in rebuilding turbos he quoted me £200 each but he said that depends wots up with them and how badly they are damaged, on the other hand i rang toyota and this is a shocka £2140 each ouch !! but the thing is he gave two different part numbers and said that both turbos are different turbo one is smaller and the second is bigger on the uk car is that true?
