Can someone please advise me on the installation of a front crank seal. I have a gasket kit with a rope gasket and I also have the type that looks like a grease seal. I'm not sure which one to use, my concern with the grease seal type is the three indentations in the timing cover where the seal goes. I'm afraid that if I just press the seal in, the outer rubber of the seal will get damaged. I've never installed a rope seal and cannot find any information anywhere. Any advice will be greatly appreciated.
