oil pressure

Should I replace my Tahoe or my engine?? I have a 2010 Chevy Tahoe LS 5.3 L V8 with 131,100 miles. Well maintained, the only major repair, I've had the alternator replaced (in my opinion, prematurely, but that's another story). The "oil pressure low stop engine" light came on so I took it...

hi, I had the issue with the drop in oil pressure when engine is warm. replaced the pressure filter & sending unit (which looked clean when replacing) still problem existed. now we have changed the complete oil pump and it still has the same issue. if all the above did not help...

I have a '95 Yukon, 4x4 with 250000 k. the oil pressure gauge reads normal on start up but after it warms up the pressure goes way down to almost nothing and the engine starts to tick on the top end. Sometimes it will come back up and the tick stops. If I turn it off for a while and start it...

While driving today the oil pressure message came on and said to stop driving. The Oil pressure gauge went to 0. I got to a spot and shut off the engine, checked the oil level and there appeared to be no other issues. Restarted the engine and oil pressure went back up to 40. Drove a little...
