smoke
 

Hi can any one help have only owend my 2005 boxster s for 4 weeks now. Why do i get a large puff of blue smoke out of the exhaust on start up after a time of not using the car,say over night or 4 or 5 hours.Then i can drive the car as hard as i like but no more smoke till the next day,or leaving it for 4 or 5 hours.
Is this normal or have i broke somthing.?

My 03 Boxster S with 15k miles does the exact same thing. I recently had the 15,000 mile service done and the dealer mechanic told me the car is perfect. I guess it's normal because of the way the engine is designed, with the cylinders low.

All M96 engines do this......

Welcome to the 986forum!

Poke around a bit (search) this is a frequent first post, the occasional plume is a common attribute of our engine design.

i.e. Cloud of Smoke

Thanks folks that has put my mind at rest.I must say my last car was an sl 55 amg and it being a great car and silly fast,my boxster puts more of a smile on my face. :)

I have a 2005 base boxster since new...
 

white smoke after seating for more than 2 weeks, overnight or 4 to 5 hrs later I'll get it check.

this one freaked me out today...
 

car had been sitting for a few days in the garage and i started it before opening the garage door. open the garage door, pull out then realized i forgot something in the house. went back in the house through the garage and i swear i thought my house was on fire. realized it was the car and freaked out again, but after a few minutes the smoke cleared then remembered reading it's somewhat common for a little smoke on startup after sitting idle for a little while.

after driving and pulling over and restarting no smoke, just need to remember next time to open the garage door ( one car garage barely big enough for the car and a ladder... ) :p

Box engines (horizontally opposed cylinders)...guess what; when the car sits, the oil seeps pass the low tension piston rings and when fired up, it burns off.

I had my S sitting on a slight downhill slope (sideways) and when I fired it up, I brought out full mosquito abatement...they were going to call the safety crew!
