Hi,

Check the condition of the PCV hoses. Look for very soft, oily or dry crumbly hoses. Particularly check the hose that runs from Flame trap to the Breather Box (look under manifold). The Breather Box can also clog after many miles/km. The other hose should run from the intake manifold to the Flame Trap. However, not sure if the layout of the hoses on your car is the same as on my 90 240DL (b230f engine)??

The oil pressure switch is screwed into the side of the engine block on the passenger side above the oil filter. If leaking replace. Easy job with the correct wrench!

Good luck,
JW
