Glyptal?

[Darryl.Richman]

No, but do tell about it. The trans case on my R52 leaks like a sieve.

I'd never heard of this but found a few links/forums where people discuss this exact issue of porosity. Search for glyptal on these pages:

A year ot 2 ago, Euro Iron implied that any decent engine rebuilder would do this to old aluminum engines but he would never give any details.

I think some of the Porsche crowd does it, too.

I think I will put this on some of the other groups to see what the response is.

The V-twin forum gives a lot of good examples of why we should stay with BMW!

Here's a link to Glyptal over at Eastwood Co.:

This might work for my transmission, but I note that its operating range is limited to 250F, and I would worry about that in a motor application.

Also, it does not say that it is gasoline resistant.

And here's a link to the manufacturer's web site:

Forget about Glyptal. It does NOT work for our application. The best is Plastikote Red Insulating Varnish. It seals and will not come off. I learned this from a highly qualified mechanic and engine rebuilder and haver used it on all my bikes with great success. Call my machinist /rebuilder Russ Bender at 1-819-684-5434 for the whole story or verification of this.

Has anyone used Glyptal to seal the inside of their porous old aluminum engine/transmission cases?
