I was cruising just about 10 minutes ago on the highway. I was going 65 and fifth and decided to drop it into fourth for fun and hammer on it. As soon as it went in gear and I mashed the pedal I noticed the oil pressure gauge free fall to the red line. I thought it was working correctly so naturally I had a heart attack and coasted off the exit I almost zipped by and pulled into the nearest parking lot. I checked the oil and the level seemed good and didn't hear any ticking. I coasted to my house about a 1/2 mile away and everything still seemed good. Anyway sorry for the long story, now the tech question. If something is wrong with oil flow how can I check? If the oil pump quit when engine was turning close to 5k would that be catastrophic?
