Photo DIY- M119 Valve Cover Gasket R/R M119 on 1999 S420

Well, I thought I was in the clear... after Re-Sealing the Camshaft Adjuster Solenoids...

Found a nice puddle on my nice white garage floors!! That won't do, at all!! ;^)

Having a look from underneath, revealed a "common" leak, from the Aft, "U-Shaped" section of the Valve cover Gasket.

Upon removal? The Gasket was as *HARD* as a Rock!! And Brittle!!

IMPORTANT NOTE!!!-- When Ordering your valve cover Gaskets? Make sure you order the "Sealing Rings" for the Cover Bolts. Also, you will "Most-Likely" Need New Breather Hoses, as well. You would be Well-Advised to "Feel" the Rubbers prior to contemplating the Job, so you have them On-Hand.

The Driver's Side (LHD Vehicles) is the more difficult of the two, as you need to remove several hoses, including the Fuel Lines. Obviously have rags to catch any Fuel Drips, and a Fire Extinguisher on-hand. Plug the Connections upon removal, to prevent contamination.

The Passenger's Side? Much Easier. In fact, I was able to Tilt the Valve Cover sufficiently to R/R the Gasket, WITHOUT the need to Disconnect the Breather Hose, or the Wire Harness.

Hope this Helps someone..
