Leaking Oil

So I got my 200Tdi installed, up and running. I notice yesterday a pool of oil under the rig, behind the engine. Hey, its a Land Rover, it leaks a bit. Today I find a much bigger puddle. I spray the underside with engine cleaner and rinse it off. While I'm rolling up the hose I see more oil on the ground. It looks like its coming from between the engine and the tranny. I unthread the wading plug and oil drains out. I know, this isn't a good sign.
Whats your guess, rear main seal?
Anything else it could be?
Thanks,
Dave

Rear main would be my guess.

Thats what I'm thinking. I'm so bummed right now. I guess pulling the tranny is easier than pulling the motor back out.

The only other possibility I can think of is the main seal of the input shaft of the transmission. Sorry to hear that.

It's actually not that difficult to pull the tranny. I did it in a morning. Much easier if you don't have to separate the transmission from the transfer case.

Looks like engine oil to me. The tranny has very fresh oil so it wouldn't have any color. This is grayish, blackish, diesel sump looking oil.

I have done rear mains by dropping the oil pan and snaking a new seal up and around. Never done a rear main on a 200, someone with more experience in this might let you know if this is possible.

If I had to do this job on the ground, without a lift, I would pull the motor rather than the transmission. It sucks to lay down and work. Pulling a motor is easy, especially if you don't have to swap other parts around to a new motor.

Yes. You need to pull the flywheel housing off and seal it properly to the block as well. It is a lot more of a job than a normal motor. I agree. Without a lift pull the engine.

I think pulling the engine is easier.


When you order parts, have Trevor send you the Elring gasket for the block/flywheel housing. Get the OE rear main seal, not the Allmakes one.


Then when you install the seal, smear some Loctite 518 on the exterior perimeter of the new seal before driving it into the flywheel housing. I made the mistake of not doing that on mine and the seal began moving slightly in the housing allowing oil to escape.
