Engine oil leak

A quick question,On my 2000 E430 we changed the valve cover gaskets they were seeping on the passenger side rear.They were redone using genuine Benz gaskets & RTV black.Its been 500 miles or so and the passenger side rear is dripping on the exhaust again.Any ideas?Could I have a bad gasket?

How much RTV did you use? Did you do the breather covers also?

The gasket does all the sealing. When I did my ML 430 I used a tiny bit of Permatex grey silicone to hold the gasket and using the correct pattern torqued the valve covers back in place. It has been holding for a couple of years now.
I also did the breather covers and used the specified sealant from MB.

My experience is the same.
RTV is for using on gasket-less covers.
When you mix 2 things, that creates only mess.
I only used some adhesive on cork gaskets.

Woah! You used BLACK RTV? It's been my understanding, the Black RTV is for SEALANT, NOT for Gasket Applications.
You applied a Sealant to a Gasket.
You needed Permatex Ultra Rubber Gasket Sealant & Dressing.
( The Gray Sealant ).

I would also recheck all your Bolts to ensure you tightened them down as per Torque Specs.

IMO the gasket job needs to be redone if black RTV was used.

It is a bummer, but the job always goes quicker the second time.
