After an oil change the OIL pressure warning light occasionally glows at low engine
RPM and the valves are noisy. I'm thinking it's had the wrong type/grade of oil used?
JA: How old is your oil pump? Has the check engine light come on?
Customer: 2003 car, 120000 miles - oil is at the correct level on dipstick
JA: Are you hoping to fix this yourself?
Customer: Yes, time served Agricultural engineer
JA: Great! What have you tried so far?
Customer: Just happened last night and again this morning, just eliminating the obvious, before going more deeply into the engine.
JA: Is there anything else important you think the BMW Mechanic should know about your BMW?
Customer: Thinking about (possibly) the cylinder heads as it's fitted with an LPG system
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the BMW Mechanic about your situation and then connect you two.
