    burning oil

    I have a f22a6. I thought the valve guides were bad because the car would smoke when I started it up. I changed the guides now and realized that the angle of the head does not allow for oil to sit around the guides. If the car sits for a day or so, I can pull the plug in #2 and there is oil on the piston. Not the other cylinders tho. I dont think its teh piston rings because the oil would drain back down...IMO.

    My question is, where could the oil be coming from when the car sits? New HG and valve guides and valve cover gaskets are on the car. I pulled the exhaust header and you can see that the oil is coming from #2 cyl.

    Any advise is greatly appreciated. I bought a compression tester today so I hope to have numbers up soon.

    Only other place I can think of right now is the valve stems are too worn, though the stem seal should have fixed that reguardless.
    Are you sure it is oil sitting on the piston, And does it still smoke on first startup - What color is the smoke?

    A "Finished" project car is never finished until its been sold.

    If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

      The smoke is blueish/gray....it smells like oil. I replaced the valve seals on teh 2 exhaust valves today. It smokes less untill I give it gas. I will do all the seals this weekend. I had the head checked and they said everyting was good. They did not change teh seals on the valves tho. I guess it could be teh piston rings. I will also do a compression check now that the car is back together and see what I get. If its the rings im selling it. I dont want to tear into the block....im just that lazy.. lol.
