oil pressure test
anyone happen to know the port to connect the pressure gauge to? thanks.
BTW: engine M276.957 for 2013 C300 3.5L.
1.OBD scanner tells me coolant temp goes down to 75 C degree on highway, I suspect a fail thermostat but no code, no engine light.
2.engine rattle on cold start, i suspect a fail camshaft adjuster, no code, no engine light.
Plus, OBD scanner tells a P0113 code, replaced a new air intake temperature sensor, but code remains. The most wired thing is the gas mileage is pretty good with 7.6L/100KM on highway, the only thing is it has a jerking acceleration.
