Kara GTT Posted May 26, 2007 Share Posted May 26, 2007 Been asked before but its started doing it alot more now!When i de-accelerate my car decided to chuck out either blue/white smoke out it did it a few month back but it seems to do it more now my car hasnt been used for about a month and when i got it in yesterday it started doing it,does anyone have any ideas what it might be,im a bit worried my turbo might be on its way out!Also what petrol am i ment to be using in it?Normal or vpower or 98 above?Thanx Quote Link to post Share on other sites
paul w Posted May 27, 2007 Share Posted May 27, 2007 Blue smoke is oil burning,could indicate different probs,best case senario it's the oil seals on the turbo.Worst case it could be engine wear,valve stem seals etc.Probably the turbo seals tho.Petrol wise don't use 95RON fuel as you will damage the engine! Use at least super unleaded/v power or tesco 99RON. Japs have 100 RON fuel so the cars are mapped for it,i use tesco 99RON in mine with no issues as it's closest to the jap fuel.

Kara GTT Posted May 27, 2007 Author Share Posted May 27, 2007 It does it in high boost when it wants to go in a lower gear it chugs and chucks out smoke! Ill try changing my petrol Quote Link to post Share on other sites
paul w Posted May 27, 2007 Share Posted May 27, 2007 Have you been running it on normal unleaded?It may be a blocked pcv valve too. Quote Link to post Share on other sites
Kara GTT Posted May 27, 2007 Author Share Posted May 27, 2007 Yes since i bought it I've only run it on normal unleaded i didnt know i had to run it on higher octaine!What is a pcv valve? Quote Link to post Share on other sites
paul w Posted May 28, 2007 Share Posted May 28, 2007 ;) Well thats possibly a knackered engine then! Which aint cheap to fix!Under the top mount on the right of the rocker cover is where the pcv valve is,cant miss it,it's quite big.Only £20 from toyota for a new one so could be a cheap fix.http://www.turbotechnics.com/docs/turbo/faults.htmhttp://www.turbotechnics.com/docs/turbo/tips.htm Quote Link to post Share on other sites
Kara GTT Posted May 28, 2007 Author Share Posted May 28, 2007 I havnt got a top mount I've got a front one Quote Link to post Share on other sites
paul w Posted May 28, 2007 Share Posted May 28, 2007 Well it should be easy enough to find it then. Quote Link to post Share on other sites
lobotomy Posted May 30, 2007 Share Posted May 30, 2007 If it's doing it on deceleration then it's more likely to be top-end wear -- like valve stem seals. Or could be as simple as the clogged PCV like Paul suggested. Quote Link to post Share on other sites
Glanza_Ragger Posted May 30, 2007 Share Posted May 30, 2007 best bet would to be check the pcv valve isnt clogged with crap, take the breather pipes off, and wash them out. if that fails, get a compression test done on the head.Could be valve stem seals shot or something else, but if its not the pcv valve, and it only puffs out smoke on decelleration/vacum then id have thought the head has something wrong with it.
