My 1999 GMC Yukon (gas, not diesel) has an oil pressure problem. After a longish drive (3 hours) at relatively high speeds, the oil filter blew out when I went to start the car the next day. All the oil leaked out into the driveway in less than a minute. I took it to my mechanic, who replaced the oil pump, but was worried about the original cause. He had me monitor the oil pressure gauge carefully, over the next few weeks, and there were no further problems (also no long distance drives). A month later, I made another long trip (6 hours) at highway speeds and the next day after this trip, the same thing happened. I started the car, the engine immediately made a loud noise, and as I turned the car off, all the oil poured out into the street. I was away from home, so a local mechanic replaced the oil filter, which was damaged in the blow out and told me that with slow and steady driving home (I went 45-55), it should make it, but that the high pressure problem still exists and I need to find out the original cause. I live in a very remote area, and although I trust and like my mechanic, he isn't equipped for lengthy and complicated puzzles. Any information would be helpful, Thanks.
have the same problem?
