dowels on the timing cover only so it will come straight forward. I have a time or two stuck a .005" or so feeler gauge inbetween the gasket and cover with the aid of a shot of brake clean everynow and then to break away the gasket without tearing, however they areusually hardened so your better off to take a razor and cut the gasket close the corners as you can on the pan and use Permatex ultra grey silicone on the bottom of cover and top of pan, little layer on both, make sure they are bone dry before you add the silicone. Sure to stop leaking that way, done it many times.
