My daughter just discovered (burning smell) while driving up a mountain side pass that her 1989 XJ is leaking oil on the exhaust pipe, and smoking. Planning to try adding Bars Leak rear main seal additive and maybe jump her up to 15W40 oil and finding some way to get the beast cleaned up (washed) without killing the TPS or electrics so she can spot the actual leak sources, but she is a newbee at that, and has no idea how to change the RMS and pan gasket, so she may may looking one of you up soon. She still has no tools (they are still here with me), and no place to work on it (apartments).
Also need to make sure it is not a CCV line clog building up pressure in the crank case combined with a steep drive uphill that caused it. I think she has already put maybe 1000 maybe 1500 miles on it with no issues, so the long up hill drive may have triggered it. The drip was definitely motor oil off the front of the Trans bell housing cover plate. The other three issues are under control so far.
Could loose oil pan gasket bolts cause the RMS to leak some?
Can one buy the Tetrachloroethylene, non flammable, paint safe, brake cleaner aerosol up there at the parts stores? It is great washing off oil fast and drying fast. But some areas no longer allow its sale, Kalifornika I hear.
