Are your valve covers covered in oil? It is most likely the upper access panels that are leaking. This must be addressed as the oil will eventually drip onto your hot exhaust manifolds and we have even seen a customers c32 catch fire due to this in the past.
Our kit includes...
New lower valve cover gaskets
Replacement stainless bolts for access panels
New Mercedes Oil Cap with gasket or AMG oil fill cap
Mercedes sealant for the upper access panels
Mercedes sealant applicator gun
