The noise has been coming from the engine for the past week and I have been told it might be the oil pump not providing oil to the sump. The tapping sound comes from the engine and increases when i change into a higher gear and drive faster. Please help!
possibly low oil or low oil pressure, the tapping may be coming from the oil operated hydraulic lifters.
The loud tapping sound can be caused by a complete heating of the engine. Worn tappets can also cause the tapping sound.
Usually it's the lifters in the engine making that noise until they become fully pressurized with oil, then they stop ticking, like on the 3 liter caravans.
chances are good in your 1996 Chevy lumina if there is a slight tapping noise, check the oil. it may be low, or you may need to add a thicker additive. good luck!
Does increasing the diameter of your exhaust pipe leading from the engine increase exhaust flow and therefore lessen engine burden causing an increase in horsepower? The answer for that is yes, but is negligible. Maybe 3-15 horsepower at best.
the doors are being placed in locked position If it's coming from the engine or transmission area, I would suspect a cracked flywheel or flexplate.
If its a legitimate knocking then you would want to go with head gasket if its a tapping you would be looking at a valve
It sounds like the engine timing. The sound is coming from your engine valves. They're not in synch with the rest of your engine. It could also be that the valves are worn out. I'd check the timing first, then the seating on the valves.
A tapping noise might come into the engine because of heat damage to the lifters of the motor. You might also hear a tapping sound if the engine has been damaged due to a blown head gasket.
hydraulic lifter? Rocker arm?
In case of Bikes: By increasing the gear ratio from the main transmission point. As the torque and speed ratio is inversely proportional so increasing the teeths of the rear end gear to the main engine gear will increase the torque simultaneously it will also reduce the pick up
Tapping in a diesel engine often means a valve lifter is beginning to fail. It can also mean that sub quality fuel is being used.
