I own a 99 Discovery I and have started a significant oil leak. The bottom of the disco is covered in oil. I crawled under to see that the oil pan and plug is ok. Tranny is all wet. Signs to me that it is the rear seals. I prefer to do it myself and have skills and time to do it right. Just not to familiar with proceedures on this one. Any help? I am too cheap to buy a shop manual. Quickly, it's starting to snow. Say ya to da up, heh!

 

Are you saying it is the rear engine seal or rear tranny seal, what fluid are you leaking?

It is the rear engine seal. I am leaking engine oil.

 

Thats a good size job, is it something you can do at home? Go you have a floor jack to handle the tranny and t/case?
If so, I would suggest you inspect and replace all the other seals fron the front tranny thru the t/case as needed while you have it apart.
Other wise it is not a technicly difficult repair.
Good luck
Mike

 

Worn piston rings also causes crankcase pressure which consequently causes oil leaks at and seals. If you already had a worn out rear seal, better replace it soon.
