i decatted when i did my manual conversion and i now have a small amount of white smoke on idle and a it smokes when reved. seems to smoke less once warm, i drove it the other day stayed off boost for about 5 minutes at motorway speeds and had 0 smoke. the car still boosts well and pulls well. i seems to remember jimmer putting up a diagnostic thing for smoke, ie hold at this rev and if it does this etc etc.

i had absolutely no issues before decatting and im pretty sure its the turbo oil seals i just want to be sure before i go putting considerable time and expense sorting out the wrong problem. input welcome guys

My car does that after getting decats, not one bit of play in the shafts or anything, just some smoke from drivers side, just a slight seal leak, don't worry about it.

yeah i checked for play first aswel. the smoke is quite noticable. and i doubt it would pass an mot now :(

my one was smoking bad and passed mot :)

il try and video it and get a vid uploaded. the mot an tax runs out in september so if i can limp on till then if it is the tubs il pull the block and have them rebuilt then. but as i say i just wanna be sure. im not one for driving around with squeals or smoke makes me feel like a ****. makes it look like a junker, and id like to at least try and look after her.

Maybe yours smokes worse than mine lol.

chances are if you refit cats goodbye smoke.it usually cures it.

i was under the impression once they go theyre gone? thing is where ive just done the manual conversion and im wondering wether its something else ive done and im chasing the wrong thing. sadly i cant refit the stock cats as the turbo elbow studs where rusted solid and snapped out on the downpipe side.

Any further comments guys I wanna work this out. One way or another

if its the turbos then oil in the pipe leading to the TB's would be a good indication .... however not having oil there isn't a certainty that its not the turbos.

 

I'm still trying to find Jimmer's guid to burnt oil... (as someone suggested)
