I was driving along today (about 40mph) and I looked in the rear view mirror and saw smoke. I immediately looked at the oil pressure gauge and right when I looked down, I saw the oil pressure gauge go to 0. It was not safe for me to turn off the engine and stop, I drove it at low rpm for about 1 minute until I could get in safe area. Everything was running fine when I shut down the engine. The head temps were normal. I have not started the engine since.
It turns out that one of the lines for my external oil cooler tore. I was able to get the car home on a friends trailer. I had fresh oil in the engine when the line tore. What are the chances that I majorly screwed up my engine? How can I find out if I did? |

Will checking for metal in the oil change your final run/not run decision? I know if I found metal in my oil I'd probably keep running (disposable motor).
Side story: We once raced a Honda CBR600RR motor in an FSAE car for an estimated 2 hours with the oil relief valve in the oil pan (not providing oil pressure to the engine). It ran ok...until the intake cam snapped and stalled. The cam thrust is so low we actually managed to start it after that too. I've never seen bearing surfaces so worn! |
