Cylinder and case sealant (Dirko) sources

[capeferrelo]

I added this to another thread, but thought I would toss it out here. Having rebuilt a number of Porsche and VW air-cooled engines, Curil T is all that goes between case halves. It's made by Elring, who also make Dirko, and can be had from almost any Porsche parts supplier, and many VW air-cooled suppliers. Automotion carries a tube of Dirko for a bit more than 12 bucks. You might also look at Performance Products, Automobile Atlanta, etc. But Automotion gets my nod.

I am not sure how interchangable Curil T and Dirko are, but they serve similar functions (and I have a tube of it laying around, so might just see.... Automotion carries those two and another Elring/Curil product.

I hope this helps some of you who cannot seem to find it where you are.

I have good luck with Dirko as well in the past, back when I was into racing watercooled VW's

I have had success with using this product

http://www.permatex.com/products/Automotive/automotive_gasketing/specialty_gasket_maker/MotoSeal_1_Ultimate_Gasket_Maker_Grey.htm

and it's about half the price, almost anything Permatex has been good to me.

I have heard good things about Threebond's 1194, it is similar to yamabond.

I agree...Permatex products work really well in water-cooled applications. But I've not found anything that works as well as Curil for sealing air-cooled case halves. When you button up a flat six or flat four, there is no gasket other than the sealant, and the factory used Curil for the sixes. Yeah, it's a bit more expensive, but I've never had a failure. A failure in a flax six gets expensive, fast.

That said, I am all for spending less for good products.

Permatex ultra black will do what the others do plus resist temps.

Dirko is a superior product for its application. An overkill for the saws. Have used it and it works great, so does Yamabond. I Still just use Permatex Copper and it is fine and cheap.

Dirko is as close as your nearest Stihl dealer.
