Ok so when I picked up my new wife (90 XJ Ltd) I was a little hesitant to just dive in, two different mechanics told me the rear main was leaking (initial inspections). After doing a bit of engine overhaul myself, I went ahead and took a look for myself. Seemed to be a combination of the pan plug and filter adaptor, I replaced the plug + washer and would love to do the adaptor today. Question is, do I have to drain the oil? No parts stores open today, and it seems like it should be ok if I let the system drain back to the pan, but I don't want to find out I'm wrong....messy. oil only has only been in for a couple hundred miles. Rear main seal....pshaww.

 

the oil wiil all be in the pan you will get some leakage from the filter empting out some food stores are open today go and get 2 quarts of oil this applies to the oil filter housung only

 

eh even if it is the rear main they are so incredibly easy to replace. you do have to remove a crankshaft main journal cap though was lil iffy on that.

 

when you do replace the rear main use the felpro gasket its one pc and silicone and it goe to the motor when replaceing not the pan

 

but if its fine just leave it be til later on.

 

Got that gasket, (and new pan, and pump) Its a bit messy under there, but I really believe the two seals I mentioned are the culprits, if not I am loaded for bear. Thanks!
