    Does your oil light come on? It is possible that it has just enough pressure from keeping the light from coming on, yet be starving the motor from oil. Is the knocking a real loud knocking, or more quieter?

This is a faulty or damaged oil pump and screen as well. replacing the oil pump and screen will fix this issue. i would do this asap. your rod bearings are suffering at this time.

Low oil pressure, and light knocking noise from back half of motor. (after engine is warm)


If the pressure is low it will turn the light on. If you have a light and hear knocking it's a sign that a rod or main bearing has worn to the point that it's allowing oil to escape from the crank, thereby lowering pressure to all other components. There is no "fix" for that short of a bearing replacement,
Expensive, and most times not worthwhile as debris from the bearing gets into the oiling passages and causes more problems shortly after the repair. Best option is a scrapyard engine or total rebuild.

I just had my routine 3000 mile oil change and was informed my oil level was approximately one and one-half quarts low. There is also a faint "knocking" noise coming from the engine when I'm driving. ...


That knocking noise could be due to low oil. There could be a leak on the following places - drain plug, on the crankshaft seals, camshaft seals, valve cover gasket, engine may be burning oil (blow by) due to bad piston rings, bad, valve seals. Regularly check your engine oil level and tap off to avoid engine failure.

I have a 1997 Buick LeSabre. It has a light knocking . it will knock a couple of times then not at all for a long while! it seems to be coming from around one of the bottom pulleys what could it be?


Tell somebody to rev the motor and check where the problem is from, otherwise remove serpentine belt, if it's a supercharged model remove supercharged belt before, and remove the accessories belt ! tell him to start the motor a short time to see it the knock sound is there or not, if not check each pulley if there's any loose or strange noise while turning them !

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.

Oil light,


There is the possibility the oil sending unit might be bad, but it is more likely that the oil preasure drops to a dangerous level when the engine is warm and the oil thins out. It would be advisable to take it to a shop and have them check the oil preasure with a remote preasure guage just to be sure before it could cause major and very expensive damage.
