I want to say the valve covers themselves can leak, as can the oil filter housing and the oil cooler (if it has one) can leak.

The car (2002 W210/E320) has about 145k on the clock and has been well cared for. It's been in the family since it had about 91k on the clock. Has always run well, been trouble free, no issues and only a few repairs. M1 0W-40 is the staple oil, always has been. Based on what I could glean, he's using about 1-1/2 to 2 quarts every 1,000 miles. No obvious smoke or leakage that I have noted in the past, nor the telltale smell of burnt oil from it dripping on the exhaust. It got one of the "updated" oil filler caps with the bigger handle when it was new. I do know that the breather covers are leaking on the valve covers, so that's the first thing I'm going to do. Other than OE valve cover seals, I presume I use the Mercedes sealant for the breather covers? It's the stuff in the white tube with the black plastic plunger, 003989982010 I believe? If anyone else here has resealed breather covers on an M112 have anything to share, I'm all ears. I'm sure it's a simple job, just want to know if there are any things to avoid or watch out for.
