2008 Mercedes-Benz CL550 ProblemsOil Seepage on Back of the Cylinder Heads
The Mercedes Benz CL550 may have engine oil seeping or leaking from the back of the cylinder heads. This is commonly misdiagnosed as leaking valve covers.
On the back of the cylinder heads there are three, in total, plastic expansion plugs that plug access ports to the camshafts. These plugs are well known for seeping oil, and leaking if left unattended. The oil will run down the back of the engine and eventually make it to the ground.
Replacement of these three plastic plugs is extremely simple, and should be done as regular maintenance. The recommended interval for replacement is every 60,000 miles.
The transmission drive selector module may fail resulting in the loss of gear selection capability. In most cases this condition will leave the vehicle stranded and require replacement of the drive selector module.
