I’m getting ready to replace my timing chain tensioner on my M119 4.2 V8 engine. After examining the new chain tensioner, I noticed the new gasket for the tensioner is metallic.

My question is - should I use loctite 5900 sealer to avoid leaks? The torque spec is only 21 Nm for the connecting bolts.

Don't use "lock-tite" just put some pipe tape on the threads if you want, but the gasket is fine. It's a crush washer and works fine .
