    5.0 oil pan gasket

    Can anyone recommend one? So many choices and not sure what is easiest or best. A gm car I had needed a 4 piece with black rtv placed in only two spots or it always leaked, always. Also my car does not have a oil dipstick. Any reason not to have one?

    I had good luck with a 1 piece Felpro, just be sure to put a dab at the sharpish edges on the main cap side and oil pan side to prevent leakage.

    I've used the one piece blue felpro and the 4-piece cork gaskets with success. RTV at the front across the timing cover and in the back at the main bearing cap splitline. Preferably under the cap to seal up that rear main seal housing splitline. Canton pan on my car with their dipstick.

    Thanks the blue fel pro seems to be the one. I got the car up off the ground and its definetly the rear main, an fittings for accusump, oil filter adapter. I can't see how I am going to get the oil pan off without pulling the motor. Is that the case with the canton pan? Drop the whole k member?
    If that's the case my list just got a lot longer. How much leaking oil is too much?

    I'm changing my rear main right now! What a coincidence. I was oil misting the back of the car pretty good.

    Probably easiest to drop the k member if the engine doesn't have to come out for some other reason. 6 of one half dozen of the other really. You shouldn't have to pull the pan to do the rear main though.

    Enough to starve the engine or get a black flag? Might be difficult to follow you.

    Read 1 inch at first. 1 foot is quite a bit and what my car was doing. The whole underneath and back was misted over. I think it was getting on my tires too. It degraded through the weekend and the car was a bit unstable by R4. Probably worth a look, don't want to start a fire.
