Full Version: Type 4 rear main seal: which kind doesn't leak as much?

I'm finding contradictory information online about which kind of rear main seal I should use when we go in to fix the oil leaks. VW, Sabo? We'll be swapping the transaxle anyway, and investigating the clutch slipping. Are there any new findings about which kind doesn't leak oil?

I guess this should be called "engine to flywheel" seal instead of "rear" since it would face the front on a VW bus.

The only one I could find that was the correct size was Sabo, I get them from gowesty.com

After blowing a rear main on initial startup of a fresh rebuild, I researched and found that SABO seems to be "the best."

Black or orange? Which is which?

The SABO I installed was black.

Sabo. Period!

I am pretty sure mine is Ehrling, 4+ years now, no leaks- did this when I did full clutch job and transmission rebuild from Dr. Evil clinic-

interesting read Perry - so it will be interesting to see if my new RMS on the boxster will last or how long, just did the clutch and IMS , it took it in thinking I had an RMS leak but it was not leaking , it was leaking from the IMS seal , but while we did all that work the shop wanted to know if I wanted to do a new RMS since the flywheel was being replaced too- so I said yes thinking new would be better and old original will start to leak - I might be wrong depending on which seal they used! ugh. time will tell! I have no idea which brand they used- hope it was OEM or the Brazil one!

Just did my clutch a couple weeks ago. After reading about it on GoWesty, I ordered their Sabo.
Definitely a nice part, much larger contact surface to the engine block. Flywheel mating surface needs to be smooth.
Time will tell...
