Hi all,
About a month or so ago I posted about oil leaking into the boot where the coil packs are from the drivers side value cover.
Dealer cleaned it out, and replaced coil. They also added a leak detection agent and came back to do a oil change, service A was due. No "major" oil leak but there is some oil seen on the engine parts not like it was last time.
Soooooo, my ask to everyone here, should I do the work to stop the "leak".
Miles driven to see the small oil concern, 1500 miles and no major oil coming from the area suspected. I plan to do oil changes every 5000 miles now and check for the "leak" then.
Miles on motor, 88000.
Looking for any advice, and how many other people saw this issue on the 2019 motor?
Is it worth fixing or give it few cycles to see how bad it is first?
Thanks all for any input.

I have the same problem on my 2018 S560. I cleaned it up when I replaced the coils and spark plugs and will monitor it from there.

The fix is expensive so don't get it if you don't really need it. If it's dripping oil onto the undershield or, worse yet, you need to top off the oil between changes then, yes, I'd get it done. In general, I don't think the valve cover leaks are ever that bad.

My car does not require any oil between changes nor is there any sign of oil on the undercover or anywhere else, only down in the plug bores. It does have a slight burned oil smell unfortunately.
I would guess the valve covers leak just a few ounces total over a year's time.
