Anyone know of a vender that makes a good engine seal for a 74 412 Wagon. Saw that Wagenteile has one, just hate dealing with out of country venders (credit card security, Euro conversion, etc.). Just took the engine out and there was a 'foam' seal. This thing totally disentigrated upon removal of the engine. Would prefer rubber. Anyone,..anyone,...Bueller?

Never mind. Should have looked before posting.

$27.95
Still, this is FOAM, not rubber. Was the original FOAM? It just doesn't seem right.

All the ones I have ever seen were foam and I believe the originals were foam.

A good foam seal will last 10 years if your don't have too many oil leaks. The other common killer for the foam is the lack of a heat shield over top of the muffler. These sheilds can be hard to find as way too many mechanics routinely chucked them rathered than deal with their hard to reach, rusty screws.

Actually...wildthings is quite right. They were always foam...and they last quite a while. I'll tell you a way to make them last longer, be waterproof , oil proof and more heat resistant.
First..find or make a stock heat shield. I have mine too....or you can fashion one from sheet metal and thin fiberglass batt insulation.
The next thing....go to your flaps . Get two tubes of Permatex super black RTV. It has a 600+ dgree temp range. Get a small stiff foam paint brush...the kind with a chisel point..about 3/4" wide...for doing windows. Its about a buck.
Hang the foam gasket up. Smoothly paint the whole outside with black permatex super RTV. Let dry overnight. Then ...get a long strip of was paper. Using one hand...split the seal open where it contacts sheet metal...paint the inside...slip in the wax paper. Do one side at a time. Let dry overnight. Its now water-proof, oil proof and heat resistant. Ray
