Well disconnected the coils and fuelpump.

Each cylinder had around 220psi. The first crank each cylinder went to around 215 then around 3 it went to 220.

Well now that I know my rings are okay, where am I burning oil 02.gif

No oil is leaking. Coolant was flushed and changed 2 weeks ago.

Just looked like coolant that has never been changed.

I had it done at the dealership because I worked too many hours. They didn't mention anything.

If you are burning oil.. I would look at your valve guides. Worn guides will let oil into the cylinder but it will not affect the compression.

If you are loosing excessive oil, chances are your PCV valve is gummed up/gone bad.

Remove it, and try cleaning it with B-12 chemtool or carb/choke cleaner. Or save your pennies and invest $5.99 in a new one.

You confused me. My spark plugs also have a bit of white at the tip, would this be the cause of running lean right? I have no 2nd sensor install because my cat is not on yet. Would that be my lean problem?
