DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

From description you have given it could be either injectors operating as they get up in mileage they can get noisey or valve tip clearances, which could be be caused through wear or slight drop in idle RPM oil pressure

My 95 tahoe has an occasional ticking noise, loss of oil pressure at idle and loss of power


Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.

Oil pressure light at idle


when the light comes on at idle do you notice any engine noise different from the norm.if not then the oil pressure sensor(ops) is bad/weak and will need to be changed.if you hear abnormal noise with the light on then you will have to have teh oil pressure checked to see if its within specs.

2001 Jeep Grand Cherokee Laredo approx 147000 miles. Recently notices oil pressures going up to 80psi periodically when driving. If I turned off the engine and restarted it would read normally. Within...


Very first thing you need to do is install a mechanical pressure gauge on there to verify what you see on your gauge. If the actual pressure is low, then it's time to start looking inside the engine. If not, then you need to trace out the electrical problem but will know the engine is safe.

Vortec 4.3 Ticking that is present at start-up and speeds up as I accelerate, what would cause this?


If you have good oil pressure, a few things come to mind, first it could be a loose rocker, secound it could be a woren or broken rocker, third it could be a weak or calaps lifter. If it sounds like its lower in the engine like around the oil pan it could be a rod or maine problem. But you say its a ticking noise witch leads me to believe its a valve trane problem.
