The Complete Engine Sealant Thread...

I wasn’t sure if my question pertaining to using silk thread as a gasket material embedded in the loctite 574 was relevant in this thread so I started a new thread. Also, not trying to steal any thoughts here, just a different approach I was asking for advice on.

My only concern with using silk thread is deterioration. The 574 will harden but the thread will not. The thread could affect the clamping force of the bolts reducing predetermined force required to prevent case shuffle. As the aluminum expands and contracts with heat, the thread can compress. If this compression allows for excess movement, the 574 can crack. All speculation but that's my guess.
I am not an engineer so take it for what it's worth $.02.

Literally billions and billions of engines have been built from all manufacturers around the globe using some version or copy of ThreeBond grey RTV. It's been proven over decades of use with very low incidents of warranty claims. No need to try to reinvent the wheel or use materials and procedures from the middle of the last century (aircraft).

Use the tried and true materials and procedures outlined in this thread. Especially when considering the labor involved in repairing a leak at the case halves on one of these engines.
