Oil leak behind flywheel I can't find Options

[tracer]

Hi all, have an oil leak that I have been trying to fix for over a month and 4 main seals. Symptom is oil coming from hole between transmission and case. My first thought were that I needed to replace the main crank seal, well long story, when this thing is leaking it seems you need to to drive at freeway speed for a little while and when you stop and look under the car the entire passenger side has oil slung on the roof and all over the trans and muffler, but only on the passenger side. Today removed the transmission and the inside cavity is covered with oil, this is engine oil and not gear oil. Removed the flywheel and seal looked dry?? Have been cleaning and scanning for anyplace oil could come from. Seems like the drivers side case shell is moist with oil and passenger side is dry. This should be an easy fix but I can't think of another place to check. Could I have a micro crack and oil leaking out under pressure from an oil galley? The oil galley plug on drivers side has been epoxied in and the passenger side has been tapped and plugged. Help!!!

you did read that the victor -reinz seal is not good per go westy? excerpt below:

"Anyway, what we found was that the common seal that comes in ALL the gasket kits has two problems. The first is that they are too narrow (width), front to back. So, when you install them in a Waterboxer, you can put them in too far, not far enough, or catty-wompus (that's Randall's technical jargon for eccentrically mis-aligned). We found one seal that was the correct thickness, a Victor-Reinz part that was all orange, and sold separately--in it's own box and everything. Interestingly, it is NOT the same seal that is included in the Victor-Reinz full engine gasket set. Go figure. So we thought, viola! We don't have to buy the stupid expensive seal at VW. WRONG. What Randall correctly pointed out is that the OE VW seal comes designed with a considerably heavier spring. None of the other seals have a spring nearly as heavy. Kudos, Randall.

What is even more interesting about this VW dealer only seal is that, A) It is all black and, It is made in Brazil (SABO brand). These two traits are typically what we refer in the industry as, well, CRAP. But, you can't argue with success, right?

So, we bought every seal VW had in the United States. Starting about five engines ago, we have switched to the VW dealer only seal. We are keeping track of which engines have them with an extra "dot" next to the engine displacement stamp we put on each GoWesty engine. Let's see if the seal is worth it. If it turns out to be the fix, I may have a trip to Rio De Janeiro in my future...

For now, if you need a flywheel seal for your waterboxer (029-105-245), we got them for $29.95 In fact, last I checked with VW, we got ALL of them! Click here to grab a new Rear Main Seal.
