My 92 eldorado has a ticking sound when car drives the noise came out no where from the passager side is it my oil pump it gets lounder when gas is apply


What is the oil pressure when ticking starts? How many miles on engine? How often do you change oil? What oil do you use? What brand filters do you use? Is this a Northstar engine?

High mileage Northstars (and others) will have tappet noise as they wear. You might try adding a quart of Marvel Mystery oil at next oil change, but if low oil pressure is the problem, try changing to a slightly thicker oil, say 20-50. If you don't know what the oil presure is, install a mechanical guage. I had a freind with a low pressure problem on very high mileage car who began using straight 50W oil and car ran another 3 years/60K miles before dying.

My 95 tahoe has an occasional ticking noise, loss of oil pressure at idle and loss of power


Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.

Oil presure gauge went to zero and computer said low oil presure! I then heard a loud knocking coming from engine! I check level of engine oil and its full, what do you think it is?


You didn't state the mileage (would help with diagnosis) But unfortunately you have suffered major engine damage. And that would depend if the knocking you hear is steady at engine idle or only knocks when reving the engine . For some reason the oil pressure did fall to zero, most likely due to bearing wear but again depends on mileage. If knocks constant at idle it is a spun main bearing, if knocks only while reving engine it is a spun connecting rod bearing. Either require an engine overhaul. Or engine swap, Once again it depends on how many miles you have the engine to determine if its wise to rebuild it or replace it. I hope this answers your Q.....

Oil pressure gauge on 1997 jeep wrangler 4.0 is coming in. shows no pressure at zero. changed sending unit, and filled oil to full but still is coming in. also when at 55 or higher mph, pressure is below...


check it out manually with a pressure gauge ,could just be a high resistance or something ,but check with a manual dial gauge and if low check put the oil pump

When my truck gets real hot the oil preasure guage starts bouncing when truck idles as soon as truck is put into park or is reved up a bit it stops bouncing


You may have a Faulty Oil Pressure Sender.
Here are some reason why your guage is bouncing:
  • Corrosion or faulty electrical connections
  • If the oil pressure gauge is pegged low after the engine is running, or is pegged high after the engine is running, or if there is intermittent illumination of an oil pressure indicator light, the sender could be faulty
You can find the oil sensor on the left hand side near the Oil Filter, as long as you don't hear your lifters ticking and making lots of noise. it's not your oil pump failing. 
Good luck and hope this helps

Oil pressure goes from around 25 at idle and almost 50 sometimes


there could be several reasons for this either the sending unit is faulty( the pressure should always rise with engine rpms) or you have a bad connection to the sending unit. Unless you have a severe upper engine noise I doubt that it is an oil pump problem.. please rate

94 jeep grand cherokee oil pressure and engine temp?


I'm guessing your engine is'nt making any tapping noise with the low oil press.
Your oil pressure sending unit is most likely the culprit.
Is your car smoking when the temp. goes up?
You engine could be air bound or thermostat could be opening too late (might need new one).
PLEASE DO NOT OPEN THE RADIATOR CAP WITH A HOT ENGINE.
