Question about Cars & Trucks
Too low for idle. Your engine has too much clearance in the bearings I'd say.

SOURCE: oil pressure light on
Yes I believe there is!! I can't think of it right off hand.I will look it up and get back to you. Also have you checked to see if your spark plug seals are worn. I am replacing mine now.I had an issue with the engine light coming on at certain revs!!!

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.

While engine is running, open the cover where you add oil to engine and see if you see a good flow of oil, if good flow, could be as easy as replacing oil sending sensor. got to realize that if poor maintenance history your engine may not be building enough pressure at iddle to move your hydraulic operated valves, only when you rev it up it will pump enough to run smooth. if running engine too long, you may cause more damage to other engine components such as crankshaft and cam shaft bearings. if you can spare a few bucks, have a good mechanic check your oil pressure with a mechanical gauge. another cheap option is to replace oil pump. last resort if you love your truck as much as we do,replace engine or rebuild it. At 205,000 this is a normal symptom, other than timing chain problems, most engines don't make it that far. hope this helps!

The Aurora is a low pressure oil system. The only solution available at this time is to increase the oil weight. I went o straight 30W to solve the idle alarm issue. Some use 20W oil and that works too.
With 20W you will be at 80 to 90psi cold then drop to 20-30psi hot.
I first replaced the oil pressure gauge and it was worse. I put the original back in and it was better. Then went to 30W and all is fine.
Running it that way for a few years now.
