    like a cold start engine knock that goes away after warming up, this wont go away. Replaced timing tensioner on passenger side and did not help. Knocking is coming from the rear center of the motor. Any ideas? Oil pressure gauge is perfect, vehicle gets regular oil changes and maintenence.

STOP DRIVING IT UNTIL YOU DETERMINE WHERE THE PROBLEM IS!

If the oil pressure dropped and then the knocking started very shortly after that, your engine is receiving NO lubrication or cooling from the circulation of the oil.
Your engine will seize and cost a ton more than it must if you continue to drive it.

What you are hearing is most likely rod bearings and the rattle comes when they no longer have a cushion of oil to keep the metal parts from hammering each other.

Either you have a catastrophic oil leak and have lost most of your oil or your oil pump has failed - the latter is very unusual in a truck only a couple of years old unless it is high mileage already - 100,000 miles/160,000 km or more.

If you are not famliar enough to know NOT to drive it, you won't be repairing that yourself either.

Oil pressure gauge at 0...oil light on...but has oil..????


Make sure the engine is not making any knocking noises when running. If so, shut off immediately as you will internally damage the engine. The knocking sound is cause by no oil pressure which could be the oil pump or sending unit depending on the year, make and model.

All your gauges are working. The gas gauge Is also working. When you fill it, you will fill over the limit the fuel level switch will go by a couple of gallons. So the gauge will not drop for a few miles. until you use up the excess fuel

Oil pressure gauge is zeroed out (0); oil is fine; engine started to knock (valve knocking). Help!! Engine was never low on oil.


Oil was check with a dipstick?then you only check its volume,here the real check you lost pressure.The oil pump supplies oil to valves to timing chain but is not the device that creates pressure, pressure is created by the cranksahft and its main bearing, if the oil pump fails then the crankshaft cannot create the needed pressure ,is the pan hit? Do not turn this on no more, youll need to get it inspected, if you run ir it will just freeze up. tow it to a repair area,

I have a 1994 GMC SUV, early in the morning when i start the engine the oil pressure is normal. but whe it warms up the oil pressure goes to 0, when I hit the gas petal the oil presssure goes a little...


You need to have the oil pressure checked with a manual oil pressure gauge you may have a bad sending unit. If the you oil pressure is the same with the manual gauge then you have a oil pressure problem.

Oil pressure drops to 0 if i turn off truck and restart it goes back up to 40


Do you have enough oil in it? If it's real low on oil the oil can't flow back into pan fast enough to keep the pump from cavitating. It might be the gauge try puting a mechanical gauge on it for test purposes. When the gauge drops to zero does the engine get louder, like it's not getting oil? Do you hear the lifters start to clatter, or rods starting to knock? If the engine sounds normal there's a good chance it's just the gauge. If it's making noise shut it off right away!!!

95 jeep wrangler: gauge indicates 0 oil pressure


Wire on oil sending unit may have fallen off or sensor itself may have gone bad. Check both. If engine has no tapping noises, likely it's not a pressure problem.

If your oil pressure dropped to 0, your engine would seize up within minutes. Most likely the problem is the oil pressure sending unit. A hundred bucks at any reputable shop should be able to take care of it for you.
