Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I NEED HELP! My '99 Boxster is blowing a steady stream of white/gray smoke out the exhaust and my mechanics are stumped. they have changed the oil seperator, checked compression, and run through mosy everything. now they are telling me that it may be a bad valve at the crank case? any thoughts or suggestions would be appreciated.

POST 2Original post

question for those more expert but generally doesn't white smoke mean water/coolant while blueish gray means oil.

POST 3Original post

Yeah, white smoke usually means coolant is mixing in with the oil. Not a good thing. I would put my money on a slipped cylinder sleeve considering the year.

POST 4Original post

Hello and greetings.I just purchased a 1999 Porsche Boxster 82,000 miles on it was driving it noticed thick white smoke coming out the exhaust pipe so pulled in and stopped and left the car sit I want to see if when I came back it won’t start and leaking oil what could be my possible problems and ways to fix it do I have to pull the spark plugs and the O2 sensors and clean them so it gets ignition to start or is it a crack block or that blow a head
