VR6 Smoking

[mriley60 0]

Hello there, my first post so be gentle. Had my L plate vr6 for six months now (my first one, always been a vauxhall man, boo hiss I hear them say, had a couple of big engined nova's etc). Anyway. Have noticed an occasiona puff of smoke sometimes, sometimes its on overrun, overtimes if I nail it for the first time when its warmed up. Personally I suspect valve stem oil seals as I have had this go on cars in the past, I dont believe its rings as its not smoking all the time. Also tappets are a little rattly on start up (although going to do an oil change tomorrow which should help as the oil is black and well used). Have been quoted around £650 to do the head. Is this reasonable?

Any help greatly appreciated.

Thanks

Try cleaning the MAF mate with electrical contact cleaner

where is that located?

if you look where the air filter is, follow the pipe from it and you will see a black plastic plug. remove that and remove the housing aswel and clean it with electrical contact cleaner, its a delicate thin piece of metal/wire. so dont touch it or move it. make sure you let it fully evaporate aswel otherwise you will set the car on fire lol

mines the same, smokes alot on overrun and on start up, it's more likely the guides as well, i looked into having the head done and was quoted £250 for new guides and a skim, the rest of the stuff like gasket and bolts I would source myself,

ps I cleaned my maf and it made no differance what so ever, I also removed the cat and changed to a new lambda still smokes on overrun so I would say it's deffo a mechanical problem

There is a step by step guide to cleaning you MAF in the Premium Members section. Just another benefit of going premium. As well as guides to doing your timing chains and things which include head gasket replacement and engine info for torque settings on head bolts and so on. Hope you get it sorted bud
