only place leaking is the vent into carb but that is due to oil tank over full.

I don't know about flipping one on an Evo. They have a lip on one end and I don't think reverse install would be a good idea but never tried it, so can't swear to anything. They only used that particular part number '97-'98 and the very few 2000 Evos they built. The seal is the same on all the Evos and it's been too long - can't remember if the length is different from the '70 thru '96 engines (24002-70) but the lip is a lot thicker on the earlier ones.

Yes, but it WILL eventually drain the primary and cause all kinds of problems...

I am talking about the metal spacer, not the seal. I have heard of flipping if there is a groove, so the seal than rides in a new spot. If I had no way to get a spacer I would.


I woiuld beasure fluid in all 3 holes. Make it right, and go for a ride,

There is no flipping around the spacer, it has a raised lip that seats against the bearing..

My mistake then. I watched some video on a pan or knuckle that had one, so I though they all did. Which is also where I got the idea to flip. I also assumed since my 01 has the timken bearing, and uses tools from evos, it was similar , My mistake,

Those small stator bolts are known to come loose, will cause the same issue.
