Does any body know why my 2004 Seirra oil pressure gauge goes really high sometimes I drive it. It goes as high as off the numbers on the gauge. Do I need a new oil pressure sensor . Thanks

Any type of weird noises coming from inside the engine

Could be the oil pressure switch-Check the oil pressure with a mechanical gauge and if normal replace the oil pressure switch abnormal the oil pump pressure relief valve might not be opening or an engine bearings problem.
