Don't skimp on gaskets. Buy the best name brand you can find.

Also, I stopped using RTV silicone years ago. It's the worst, especially in contact with oil.

Here at the shop we have two go-to sealants.
Permatex Gasket Dressing (part no.09974) or Permatex Right Stuff Gasket Maker (part no. 25223).

Getting back to the coolant leak, how old and how many miles does your motor have on it?
Ford & Dodge motors (the older stuff) were notorious for the timing covers eroding out and leaking. Thermostat housings too.
Coming up in my Dad's auto salvage, when we pulled a good aluminum timing cover off an engine core it was pure gold.
Keep an eye out for this when your doing your repair.

I don't see this happening much anymore on newer cars.
Guess the metallurgy has improved over the years.

no sealer sticks to oil . . clean the surfaces . . the right stuff is good but has a shorter working time than permatex therefore it is best used by experienced people that can get the job done quickly.

none of the over 100 timing cover gaskets we have installed ever leaked and every one was done with permatex gasket maker.

The motor was built in 2009 and has 14k miles on it. Everything except the block was new. The gasket was a Fel Pro. I'm really kinda surprised that its leaking. It has been off and on for quite some time. The water pump was replaced once, but I'm not even sure if it was the actual problem now.

I think that the design of having the water pump bolts going through the timing chain cover to mount it is a bad idea. Every time the water pump is removed, the risk of the timing chain cover leak increases. They should have had the timing chain cover bolted in place and the pump mount to the timing chain cover. They should not share bolts.

I have used RTV on those ports in the past. Never had a problem that I am aware of. I've never used Permatex #2.

I am looking at Cometic with a rubber and steel core.

FelPro makes a cork rubber seal too.

Has anyone used either of these?
