    Rear Main (Crankshaft) seal

    Just FYI, I can confirm that the Timken 716102 is the replacement seal for the rear main seal. It is listed in their catalog as the main seal replacement for most Audi's. The seal is actually approx 2mm narrower so I just split the difference when pressing it in. I got mine from Amazon for about $20 delivered, much cheaper than the whole assembly from Audi for list of $350 and only discounted down to about $250. You will need the gasket for the flange when re-installing which is 077103181H for about $13.

    I bought one of those seals in case I run into a leaky one and after 100+ trans removal I have yet to find one leaking. Leaks are coming from the valve cover and run down onto the bell housing behind the flex plate.

    When I swapped out the trans years ago I felt guilty not swapping out the RMS. But since I was doing the conversion I thought I would do it this time but now Tozo just jinxed me, the new seal will probably leak

    I sent you a PM on this but will throw it out to the others here, too.

    How did this Timken P/N work out for you? I've seen that the reviews of similar seals (not the exact Timken one) have bad reviews and leak immediately.

    The felt gasket piece seems to be specific to the OME one, no?

    Also, did you have to remove the RMS housing to replace this or did you do it with it in place? Do you have any pictures of yours leaking? Did it look like this?

    Mine was leaking from the actual seam between the bottom of the flange and the upper housing of the oil pain. The seal itself was fine. I replaced the entire flange. It was $297 from ECS, I'll have to check the parts list. The $20 vs $300 debate on the part is just foolish as the labor involved in repairing this leak is thousands. I would not dare replace it with anything but OEM.

    Since Bentley Publishers is in the stone ages with their software, do you happen to have the torque specs for this?

    I think it's 10 Nm for the ones attaching from the back side (between the gasket) but I'm not sure what they are on the underside (between RTV).

    Thanks both of you. Mine only works with XP and I've not tried to run an XP terminal or contact Bentley for online access ...

    I spoke with the Bentley people. They are apparently stuck with XP. Windows just blows in their backward compatibility department. Even trying to run XP compatibility mode will not let the Bentley stuff run. You need to run an Emulator or a copy of XP.

    They are going to release the full Web Version soon, it is in BETA and I was allowed access to it. It works GREAT! LOVE IT.
