I am having trouble with the rear main seal of my XJ (1988 4.0 Renix). It was replaced a few months ago and it's starting to leak again, so I have some thoughts, let's see if there's something right with them.
1. It started leaking a few weeks ago in a whelling trip. Is there something that can cause the seal to start leaking after some heavy usage / abuse? I didn't really hit anything.
2. Can bad motor and tranny mounts cause early damage to the seal?
3. I bought a generic one last time, maybe that is contributing to a soon failure, but here in Mexico we don't have too much options for old vehicles, but I found that Autozone might have the following here in my city: FELPRO Rear Main Seals for a 1988 Jeep Cherokee 4WD, PN BS40612. Would this be a good guess?
4. Any other ideas assuming that the changed seal did work fine for a while?
And, I also have trouble with my valve cover; it has a new seal but it still leaks. My technician told me it was somewhat bend, so I should consider replacing the valve cover. The 1988XJ has a terrible choice of a valve cover, so I'm thinking about one from a 1992 or similar XJ (with a much better oil cap). What would you consider to get a cheap and good solution for this?
Regards
