Early morning I go out to warm it up and get it started. While running, i am scraping the frost off the windows when after a short bit, the motor starts sounding a bit knocky. I quickly look at the oil pressure and its 0, so i shut it down before i do major damage. I look under the front and there is all my oil on the pavement. I cannot see where it came from but most under the level of the oil filter is wet but not dripping with oil. O dark thirty so it was hard to see so i left it to not be late for work right after stopping the oil puddle.
Today im under it trying to see what happened but cant visually tell yet. there is an oil drop hanging from the Pressure sensor unit so it came from above.
Anyway, I hate to ask because i figure its bad news but what are the thoughts on what happened? And did i just hose my motor?
