[QUOTE="Flyer58, post: 426958, member: 18629"] With the 2.5 the one piece rear seal may be easy for some but requires a lot more work. You need to pull the flywheel off to get to the end of the crankshaft. Installing the flywheel is tricky because they use stretch bolts which are torqued to 50ft/lbs then turned another 60 degrees. According to the factory service manual they're "suppose" to be a one time use bolts but I doubt many listen to that. I called the local dealership and they located the last 6 bolts for the YJ in the country at a little dealer in Michigan. I think I've read TJ bolts may work too but didn't verify that. Unfortunately it's not a job I'd try lying on my back in the driveway like with the two piece seal. Can you bring it back to that shop to verify the new valve cover gasket isn't leaking or maybe it's something else? I had to rebuild my engine because the oil pressure sending unit failed and blew out all the oil. Unfortunately the previous owner didn't catch it in time. No oil is bad... [/QUOTE]
