Engine Mechanical problem
2001 BMW 325 6 cyl Two Wheel Drive 177555 miles
little bit of oil comes out of the oil filter cap when the engine is running. The service engine light came on after the oil change and where is the oil pressure relieve valve and the oil pressure sender switch located. The yellow oil lamp comes on within the first minute of starting it, stays on for 12 seconds and then goes off and never comes back on.
I request you follow your original thread so we can stay on the same page. The yellow oil can probably indicates the thermal oil level sender is faulty, you can disregard it or not, it is not going to affect anything. Or replace it. Is there service history on replacement of the cyclone separator? Or the oil filter housing profile gasket?
