Video - occasional white smoke on startup for a second or two


Recommended Posts

Hello,

 

Please have a look at this video:

https://www.youtube.com/watch?v=4WD1b8naXgo

 

On my car it only lasts for a couple seconds. This occurs perhaps 1 per 20 startups and I have a strong feeling that only after cold nights or during cold mornings (defining cold here as 40-50F). I drive this car on a daily basis.

 

Would you consider this normal behaviour?

 

Many are posting similar questions like mine but without a video it is hard to judge if it is fine and occurs because some oil flows past rings to combustion chamber due to Boxster engine layout. Also some are talking of white, some grayish and some blue smoke :-)

 

My car is 996, 2004, 3.6L, around 90k miles. AOS, plugs, coils are brand new. Both exhaust and cats look like brand new when borescoping. Leak down test >96/100PSI each cylinder, does not consume oil or coolant. Oil level is very close to maximum level, perhaps a tad lower than maximum. Using Motul X-Cess 8100 5w40. 

 

 

Thank you!

Mine is a 02, 3.6. I get smoke on start up like that every second week or so. My smoke is blue though and I burn oil like mad so I believe my issue is ring/cylinder related.

If your not burning any oil and the car is running fine, I wouldn't worry too much about it.

I would not be overly concerned.  Because of the horizontally opposed design of these engines, they occasionally do this.
