I too had a leak recently on the driver side.
New rubber gasket and proper torque ( 10 nm ) remedied it.

 

Thanks for the confirmation sirharper

 

Or as George on Seinfeld would say ‘shrinkage’.

 

I bought the gaskets from Rob at Needwsings and did the work myself. I went so far as to pull the cover assemblies (valve and breathers) off the car and do the work on the bench. Put about four-five hours in it. I took my time, did it right, and it's done.

No leaks to this day. Order good stuff, take your time and do it right - otherwise, like so many others, you will do it over again soon after.

 

Thanks pizzaguy, my thought process is do the passenger side first a weekend in the next week or two. Then the following weekend do the driver's side and take my time. I did get OEM from MB for about $40 total, got the hoses from pelican and bolts from needwings. Already changed the plugs last week took me about 3-4 hours taking my time. What i noticed was that the coil pack plugs to the cylinder plugs are numbered so just had to number the coil pack themselves which was first and last coil packs on either side. Did one side at a time.
