1998 C280 M112 oil pressure test port leak
Just replaced the oil pressure test port on my C280 (152K), and if still leaking
profusely. I have the updated cover and gasket and the gasket is set with the
flat side facing the engine block. Both E10 torx bolts were torqued to 12 NM.
I started the car and let it warm up, rev it up to 2500 rpm and held it for a
but and no leaks. I drive it to work (20 mins about 10 miles) get there and
check and the oil is pouring out of the side of the port cover.
