Depending on the amount of miles, maintenance records, or how hard the car has been driven either by a previous owner, or by yourself. The engine's main crankshaft bearings or the connecting-rod bearings could be excessively worn.
Also, it could very well be a wiring problem to the sensor and/or computer causing the problem.

maybe a dumb question, but have you checked the engine oil level (not trying to be rude) . if you have check the type of oil filter you are putting on. But you mention tapping noises....do they increase slightly as engine rpm increases then dissapear. if so, i would wager that the noise you are hearing would be the hydraulic lifters. the reason you hear them is that they are not getting a sufficient amount of oil pressure...your oil pump might be dead or dying...would go that route.
also, ensure that you are using the correct weight of oil in your vehicle (follow manufactures recommendations)
hope this helps.

That is normal, my truck , if it had a light , it would be on, the gauge goes to about 0 when idling and flies right back up when going, When it stops moving is when I'll get worried about it. You might try heavier oil this summer and see if that changes anything. Go with a 10w40. If you are already using this, try straight 40 one time. Hope this helps.

Testimonial: "Thanks for your help"
SOURCE: truck has low oil pressure
The gauges on some of these weren't overly accurate so I would suggest having someone test the oil pressure with a mechanical test gauge temporarily installed in place of the oil pressure sending unit to see what the actual pressure really is with the engine fully warmed up at an idle [this is when the pressure would be at it's lowest point] If you have 15 psi or above then that's about normal. If you have less than 10 psi then that's getting fairly low and could be the result of worn internal bearings. If you have good oil pressure but your gauge reads very low then you might just have an inaccurate or faulty sending unit that isn't reporting the right pressure reading to the gauge. Once you have the actual pressure tested you'll know where to look next.

If your sending unit is one wire, unhook it from the sender and place a jumper wire from wire to ground. Turn ign on, gauge should pep high PSI. Two wire plug, place jumper between contacts of wires (unplugged). Same thing. What this does is isolate the gauge. If gauge pegs on test, replace sender. If it does it again with new sender, it's the pump. But it's probably the sender.
