6.3 oil leak question

Hello all

I'm looking to buy my first AMG with the 6.3l engine. Everything checked out fine except for this


6.3 oil leak question-img_1026_zpsf3madprj.jpg

Is that normal on the 6.3L engine? Valve cover gasket like the 5.5? Thank you for your guidance

E55
pretty common. there is a valve cover gasket and the front cylinder head cover gasket. they both should be done at the same time.

E63
Mine E63 in the shop for valve cover leaks

It got bad enough that it started to burn on the exhaust. Dealership said $800-$900. LOL. That will be the smallest bill I ever got. It's not a poor mans car.

That's good advice to do both, I didn't know and in less than a year a second leak (Mercedes dealership called it a timing cover gasket) cost me way more than had it been done the first time.

I think I have the leak from the cylinder head top front cover, on the right. Can someone please let me know the part number for Timing cover gasket? Can this be a DIY? Is there a procedure for this? I couldn't find one. Thanks.

if you're doing the front cover i'd recommend doing all your gaskets, seals, o-rings, etc. this will help avoid repetitive work when another seal leaks. more money upfront for an inevitable leak to come with mileage.

valve covers
front chain seal
oil cooler thermostat o-ring
oil cooler hard line o-rings
oil pans if leaking...upper pan should be done with front chain cover as they'll share a joining face. lower pan can be done on its own.

valve covers are obviously fairly easy and can be done individually. probably the same with the cam phasers?
