My recently rebuilt Type IV is leaking oil between the cylinders and the case. This engine is now a 2.4 L (was 1.7) with no gaskets or shims between the cylinders and the case -- common practice. So what is the best sealant and best method of application?

Yamabond 4 is my engine-builder pal's choice and notes that in his race experience, it holds up in cylinder to case applications that see 10K rpms regularly. This goo is a silicone based liquid gasket that fills gaps on a flange surface and prevents leaks. When cured, this product forms a rubber-like body that resists heat and seals joints subjected to high temperature. It is gear and engine oil resistant, Yamabond 4 Motorsports sets in 60 minutes so you have time to work with it if chasing rings etc.
