Oil Pressure Buzzer On!! Hi!
My family and I are supposed to be leaving for a 10 day road trip on Saturday. Unfortunately my 87 Westfalia has decided to "act up". As of right now, the oil pressure buzzer has decided to come on this afternoon. I've done an oil change recently and other work, and had an interesting problem this morning which I thought I fixed, and I'm not sure if this morning's problem is related to the oil buzzer. Here's the background: 1. Changed oil and filter on Saturday. 5 qts Mobil 1 10-40 High Mileage...tossed in a pint of "Restore" for good measure. Looking back at it I probably overfilled the engine by 1/2 a quart. 2. Driving today up a moderate hill at 45 mph, 4th gear. Smoke billows out of exhaust, some power loss....stopped at top of hill, shut off engine. Checked for leaks - no leaks. Restarted engine, smoked for 10 seconds, and then smoke cleared. I suspect that going up hill with an over filled with 1/2 quart oil, oil got sucked into breather and into throttle body. 3. Drove home (7 miles) no problem...no smoking, no loss of power. 4. Took apart air cleaner, intake hoses, and throttle body. Found oil covered inside of hoses and throttle body. Cleaned oil out of hoses, etc. 5. Removed spark plugs, all clean, no oil fouling. Assumed that oil burned off. 6. Put it all back together. Started engine, ran well at idle. Shut engine off. Assumed that all was well. 7. About an hour later, got in the Westy, started it up and drove off. About 1/4 mile later, the oil pressure buzzer came on at 3k rpm. Drove home. 8. Remembered about an old post to the list where Fram filters caused some oil pressure problems. Replaced new Fram filter with new Bosch filter. No change in buzzer. 9. Checked all oil pressure sensor wires and connectors, all seem ok. Ok, I'm not a firm believer in coincidence....so I suspect that the oil buzzer problem is related to the earlier ingestion of oil through the intake... Anyone have any ideas on things I could check? Or should I cancel the trip and start thinking about a new engine? Current engine has 146K miles.
Thanks in advance.
