[Fot] [TR] Sealants used on Fo8 gaskets

[Joe Boruch]

 Phil, how are you using the Anearobic sealant? Are you still using felt, or are you filling the gap where the felt would be with the Anearobic sealant?   JoeB.

 Joe;We’ve used the two of them together in two different engines. The Permatex was washed away from the rear main seal cap sides in both cases.In fairness, in that application it takes a very long time to dry, and so it may have not set completely before we ran the engine. But we never had that issue until using the Driven synthetic oil. Which, BTW, seems to be really good stuff!  Thanks to Ken Knight for  the recommendation.We’ve switched to Permatex Anaerobic sealant and it works very well. Much easier than soaked felt....Phil Gott

 Thanks David.  Driven says that their oils should not cause your issue, but they think you may have an issue with fuel dilution.  They did suggest not to use the Aviation Permatex, since it can be affected by aromatic solvents (which is what gasoline is).  I looked at the instructions for Permatex Indian Head gasket shellac and it does not say that it is affected by aromatic solvents.  The instructions for Aviation Permatex say that is affected by aromatic solvents.  Looks like for my next build that I will go back to using Indian Head (if it has not been deemed to be un PC by then).  
Thanks for bringing this issue to light.  Joe B.

 Hi Joe,
Here’s some pictures of the felts in my engine after being washed clean by Driven XP3.  You can see the cement is washed out of the felts upon removal, and also the permatex parted along the seam of the block/cap.   Never happened before running the oil.  Hondabond held up just fine afterwards.
