my first post

 

Blue Smoke means you are burning oil.

 

ya i get it to some times!

it is cause u are burnin oil

if i let my car idle for a while then hit the gas i get oil smoke out my exhaust!

 

^ yah oil is getting into the cylinder.

Do you check your oil often?

 

very often!

 

Are you losing oil?

 

Visible blue smoke means oil is getting into the combustion chamber, either past the piston rings or from leaking valve seals and being drawn down the valve stems from the top of the cylinder heads. A compression test might be able to tell you which cylinder is the worst offender but a leakdown test using a gauge and compressed air can narrow it down further.

 

then its not the turbo ... leeking ? or is theat out of the question ?

 

The turbo could have a failing oil seal. If that's the case, a compression or leakdown test will not find the problem. I'm not sure how to diagnose a failing oil seal except by removing the turbo and inspecting it.

 

it is my turbo!!

that is why i get oil sumtimes!

ill see 03 impreza al today and ill speak to him bout it but ery one i talk to says it is my turbo!
