Problems w/ the STI

What would cause an STI to misfire in cylinders 2 &4, spit oil out the BOV and smoke come out of the exhaust.

that does not sound good at all.. u taking it in soon i hope..


(for oil to be coming out the bov it sounds like you have a blown turbo seal or worse, but that would be causeing you to misfire on more then just 2 and 4..)

a bad. bad. bad turbo seal.

Dont drive it if you can avoid it, the turbos going to seize, you're going to foul the cylinders, and the rings are going to flood.

I have seen misfires happen when the intake air temp sensor reads that your car is too hot and begins to dump fuel.

If the oil problem goes away you have nothing to worry about. It could be the seals of your turbo. A small amount of oil is ok, a larger amount is not.

I took my car to the dealership they told me it was because my timing belt jumped a 1 1/2 teeth. They are waiting for the parts to come in. After they work on my car I will inform everyone.
