There was another hole just as big as this on the other side of the engine.
I didn't get a good shot of the holes in the oil pan. I am impressed with how clean it was inside. Apparently, my strict regimen of "whatever was on hand" worked.
Was this done by trying to compress coolant?
When the engine blows up does the OLM go to zero percent?
Did I miss something? Tell us how this happened and were you driving down the road when it came apart?
