Engine oil under tranny

[porsche34]

Hello folks...,

This morning i had a look under my engine and i found a small oil drop(but not yet on the floor) under the tranny located exactly on the alluminium skid plate under the transmission.

That was for sure motor oil and not tranny oil....the oil was light brown and clean.

I was wondering how i can find motor oil under the tranny since it seems to have no oil leak between the engine and tranny (RMS....).

I had a look at the engine and i did not see any oil leak at the IMS flange....i didn't see any....

Any idea from where the oil drop..

Thanks

It could be the differential oil and it is brown in color and has distinctive odor and mostly on the right side of transmission assuming you have a tip

Thank to you Flybox.....

You are right,on the right side and it smels different then the engine oil.

I assume now i will heve to change the gasket or O ring on this side.....

Thanks a lot

Robert,

It is a messy job and you have to take the right side drive shaft to replace the o-ring.

So I would keep it simple for now, clean the area and see where exactly the leak is

coming from before you start the job. 2 place leak could be coming from either the filler

plug or the o-ring.

If it is the o-ring, you have to be very careful taking the differential out. It is heavy and

whatever you do, don't drop it.

By the way, there is a torque sequence when you put the differential back together.

Good Luck
