Initial use of AT-205 in engine oil to stop likely RMS leak not successful...

[Dawg82]

I've been told by mechanic that I have an RMS leak - with the corresponding big labor costs to replace. Decided to go the AT-205 route, hoping for cheap fix. Still leaking. Worth it to continue with another dose of the additive at the next oil change?

I’ve never really seen many people have luck saving a failing seal with additives.

Welcome to the forum. Additives almost always are just a band aid at best and sounds like you know that. I saw an RMS leak on a Ford van one time, camping weekend, and the guy added 2 tablespoons of brake fluid to the oil and idled the engine and the leak stopped till he got home and fixed on Monday. I was really surprised.
