They didn’t bother. The shop here is more like a brake, muffler, oil change place. They can’t do this job and had no intensions of doing more than looking at the oil.
I didn’t know that going in. It makes me feel better knowing it can be shipped home busted.
I will see if I can get the codes before the battery dies. Maybe get a clearer picture of what happened.
Based on what you have told me, what I read on the interwebs, and what I experienced while driving, I think the pressure relief valve stuck open.
The last drive before the failure involved a max effort, red line acceleration onto the autobahn. Maybe, the valve got stuck open there but I was close to home and 🤷🏻♂️ Why the light stayed off in town, and idling as I came home.
Maybe, just maybe, the oil system which is fully primed can continue to operate with the relief valve stuck open. But after a shut down and draining to the pan, the oil would rather take the short cut path? I am only getting very speculative info about how this system works and I have no schematic.
So, next morning, cold start, the oil pressure light came on because oil rather divert through open valve than pump through engine. I noticed low level on stick and added more oil, but that was a red herring.
Pump was probably working fine. Maybe some oil was moving through engine as I putted along. I made it pretty far like that. Then I had to drive a long uphill section. Not crazy hard pull, but enough to overwhelm the minimal oil going through engine.
At that point 😥, she was probably struggling inside. Temp guage was low/normal, but metal was getting removed somewhere. The shut down as I idled and coasted down the hill into town may have been a soft seize? Never seized a moped. Maybrrr I have seized a Pilot.
After I coasted to a stop and sniffed around, the restart was smooth and easy but accompanied by a knocking sound. I assumed that was a failed oil pump. More likely (and even more sad) it was just a wallered out engine telling me what an asshole I had just been to it.
I never knew how oil pressure was regulated before. I do now. Lots of great life lessons learned here. Wish I had followed the rules and obeyed the light. Thought I was smarter and got schooled hard.
Thanks for the help.
