Puff of thick smoke on startup???

[Dave88]

I\'m getting a decent puff of thick smoke right on startup sometimes and doesn\'t seen to matter what type of driving iv been doing prior. The smoke disappears after 5-10 sec after startup and apart from that the car runs great with no other issues.

Thoughts?

White smoke on startup is also common. Condensation in the exhaust.

Smells like oil?? = compressor seals

LOL could be 1 of several things. if your trying to imply its DEFINITELY compressor seals you are full of hot air.

most of the time its actually a small film of oil that sits the bottom of the bores, given the horizontal piston nature of our engines, and so it pools, and then burns off at start up.

Not implying anything! Like you said it could be anything and comp seals could be the 1 of many

My coupe did this. Puff of white smoke on start up.

Wouldnt ALWAYS do it.

Led me to believe the seals in turbo were shot. (inside of intercooler/piping were oily as fuck aswell)

Never got round to fitting replacement turbo due to some scum nicking my ride.

Mine did this til I got a catch can. Also wouldn\'t do it now if I took the catch can off since i\'ve bought the boost down

Mine does this occassionally as well. Light, white puff of smoke on start up.

Horizontal bores ppl. 99.99999% of all start up chuffs.

If it chuffs away on over run or on boost... -> then turbo seals

Mine actually stopped its white puff over Winter, coming into summer my white startup puff has come back. (Or I just started noticing again lol)

Mine has done it on and off depending on circumstance since my rebuild years ago. It doesnt smoke on boost or anything and drives strong still so so I\'m not concerned.

Lets face it tho your car is hardly a good reference for anything. High boost untuned can have funny effects.
