    I cant seem to get it off after removing all the bolts.
    I have the one piece felpro pan gasket.
    Can I get away with just removing some of the front oil pan bolts and lowering the pan?

    Yep unfortunately. The timing cover holds the front part of the oil pan gasket.

    ^ Correct. The pan needs to come down or you will bend the timing cover trying to remove it.

    Remove all oil pan bolts and leave the 2 rears loose and you'll be able to remove the timing cover.

    Copo your advice is spot on I could not get the pan to drop until all of the bolts were loose. Sounds like you have done this before, if so did you have the felpro reusable one piece seal and did you reuse it with no leaks.

    If you clipped the corners of the timing cover where the front lip seal sits on the oil pan before you installed it then, no, you don't even have to loosen up the oil pan. That is SOP whenever installing a new timing cover for me.

    NO! I've removed the timing chain cover from too many SBC's without dropping the pan to recall how many dozens I've done!

    You pry it of from the top and it'll pop right out. Now getting it back in is the tricky part. You need to take tin snips an trim the edge of the where the pan to cover meet so you can "pop" the cover back on. I used to have a picture of it here from my photobucket account but the link doesn't work!

    OBTW, change the timing chain cover seal AND put a repair sleeve on the crank = eliminate a co leak on a SBC.

    Depending on the engine and what it's in, I remove the oil pan for an original equipment timing chain replacement. Back in the day, the factory (and not just GM) used nylon on the chain gears and this will come apart over the years. By removing the oil pan, I can clean all the pieces and other just that builds up. Keep in mind that if it's a pre-catalyst car that ran on leaded fuel, that silvery grey build up is tetraethyl lead build up. Use gloves to clean it. It's highly toxic.

    I think that was before the one piece oil pan gasket days. You would have to cut out that nice one piece front seal and install a new one. It's going to be hard to save that front seal without dropping the pan as far as possible (in a Camaro). Those 2 piece timing covers are starting to sound pretty nice about now.

    I’m on my second 2 pc. timing cover & both have leaked at the bottom. The second one has 2 screws at the bottom & will leak if I don’t use two gaskets. FYI
