Why does my oil pressure drop when idle at red light. There is no knocking in engine. If you give the truck a little gas and hold the pressure will go back up and stay?

There may be a leak in your pressure valve. Take it to a machanic to be checked out.

Why does your 1994 Chrysler Lhs oil light on and the engine is knocking?
When the oil light is on, it means you have low oil pressure. This can be caused by low oil level. When you first start the car, the oil light will come on momentarily, then turn off to signify that proper oil pressure has been reached. An engine knocking usually indicates that the engine is about to stall.
What does the oil pressure light look like?
There is no such thing as an oil pressure light on most cars. Some cars have oil pressure gauges, and all have a "Engine" light or "Check Engine" light with a picutre of either an oil can, or Engine Block The oil pressure warning light usually looks like a little red oil can. The check engine light looks like a little yellow engine.

How do you know if your oli pump is working?

Could be rod bearings - not a good sign. This is a sign of pre-failure of the engine.

You have 85 celebrity 28 carb loud knocking from lower engine loss of power oil changed regulary no leakage usage took oil cap off with engine running looked dry could it be oil pump or rod knocking?
The rod knocking is caused by loss of oil pressure. Did the oil light not come on? That light is red, red means stop. Do not start this engine again until the problem is corrected. You are probably looking at way more than just installing a new oil pump if the engine was run for very long without oil pressure. A complete overhaul may be in order.
What does it mean when engine has a knock and the oil light is on?
You need to have a compression and oil pressure test run. Do not drive it to the shop. Have it towed. Running this engine in this condition will do some serious damage. You have zero (0) oil pressure and that is why it is knocking and showing no oil pressure. It may be damaged so badly it needs and overhaul. It all depends on how much you drove it after this happened. If you immediately shut it down there may be very little damage. If you continued to drive then it will have serious damage.

1986 Chevy Celebrity 2.5 oil light on top end tapping?
The oil light being on indicates low or no oil pressure. Low oil pressure can be caused by: Engine is too low on oil. Oil filter is plugged up. Oil pump has failed. Oil pressure switch has failed. You should not run the engine until the oil pressure problem is solved, major engine damage may occur otherwise. The tapping may be caused by the hydraulic valve lifters being out of oil. A loud knocking noise may mean your engine bearings are already burned out.
