M112 Valve cover gaskets
 

2005 E320 (M112) has 95k and valve covers have been leaking for what looks to be a long time.

After reading it seems leaking valve cover gaskets ( & breather covers) are very common with the OEM valve cover gaskets.

I've found, OEM, Elring ( which is supposidly OEM but not sure if there exactly the same?), Mahle, and Felpro.

​​​​​​I really don't want to be dealing with this again in 80k miles so which one of these is the best?

Thanks

There is no best, they all leak eventually. 80,000 miles on a set of valve covers is wishful thinking. You'll be lucky to get 50 k.

Ok let me rephrase the question are the Elrings & the Felpros better, same, or worse than the MB originals as far as sealing and lasting?

On my 2005 E500 (M113) I went with genuine M.B. gaskets.
They are made by Bruss.

I've read many posts about using aftermarket valve cover gaskets and they all leaked.
Pay a little extra and get genuine.

Get the original. I put on Elring and they started leaking within a week.

I didn't hear anything back immediately so I already ordered a set of Elrings from fcpeuro, did you use any sealant when you put the Elrings in?

No sealant was used, mainly because I did not see any sealant from the factory when I opened up the covers. Having said that, next time I may use a little for the areas with sharp corners. Funny thing was that the Elring I was using looked identical to the original that was on the engine.
