Don't rule out the possibility of a slightly out of spec sender. The oil pressure sender in my '89 tended to set the buzzer off at a bit higher oil pressure than it was supposed to until I replaced it, causing exactly the same symptom. Also, how long has it been since you changed the oil, and what is its viscosity? I've found that the wasserboxers tend to like 20W50, especially if they have some mileage on them. (Thicker oil can mean higher pressure, of course.) In any case I'd start with an oil change, an oil pressure check when the engine was nice and hot, perhaps a new sender if called for, and if all of that fails, even a slight stretch of the oil pressure relief spring before I started to worry too much. - Ron Salmon The Bus Depot, Inc.

I was driving down Interstate 5 heading due south, going about 80 mph, saw a gas station, decided to exit when at that moment the buzzer went on. Water temperature wasn't higher than the top of the led itself. I turned the engine off, and coasted down the road, into the denny's parking lot next to the gas station. Let it cool, let my mind run wild. Added more than half of a bottle of gunk. Wasn't low on any fluids. After a few hours, I started, it ran, and I drove 60/65 mph all the way to Riverside. No problems since then. Thinking is, oil got hot which made it thin out which caused the oil pressure to drop. It wasn't that hot that day. Is this just a day in the life, or is it an omen? |
