For racing or sport engine that are disassembled on a regular basis it is fine.
The product is basically the same consistency as Curil T and should only be used in similar applications.

In the case of weeping chain box gaskets that had 574 thinly applied a simple retorque may cure your weeping issues.

I agree with your theory.

I have used Hylomar for about 10 years (on F-15/16 engines) and I dont think I would use it on 911 case halves.

We use it a lot on the engines but they leak like crazy, plus, constant retorquing is required as it acts squishy under the bolt heads.

In general, anywhere Hylomar is applied usually results in oil leakage.
