Where to put sealant on M103 lower timing cover
I'm working on sealing the lower timing cover on an M103 and I was wondering if you're supposed to put sealant around the hole that goes through to the chain tensioner, I saw a picture of someone online that did not seal this area and I've been unable to find any information on it.
It looks to me like this hole is used to pressurize the back side of the chain tensioner with oil and I figured it should be sealed but I haven't seen anything that said definitively whether it should have sealant around it.
I'll try to attach a picture of what I'm talking about
