  • First check the oil level and make sure it is full.
  • Sounds like your Oil Sending Sensor is Failing. What happens when it fails is the oil pressure drops and the light goes on. You can test it by pulling the sensor and putting a gauge on it. If you have 6 PSI or better in park and 55+psi in gear then it is good. When the pressure drops so to does the circulation. Drive it to long like that and you risk seizing your engine. Replace that sensor immediately if the pressure is not as it should be.
  • This can also be a weak oil pump.
  • I recommend checking in the order I listed. It is more than likely one of them.
Good luck to you, Regards, Tony

Pound ticking noise when my 99 durango starts goes away after the engine warms up

The ticking noise could be a faulty hydrulic valve lifter. When last was the oil & filter changed, it coul be that the oil is thick and not going through to the lifters and when it warms up the oil is thin. It could be that the engine is need of an overhaul as 148.000 miles is 238.182 Kilometers and that is a hi milage.

Got very bad nock in motor all fluids and gages are good. Engine light is on

Did changing the oil cause your light to go on? You didn't say if the noise started all at once or if it has gotten louder over time.

Typically a knock not related to predetonation ("pinging") will typically come from the connection at the crankshaft to the piston connecting rod. A slapping sound may occur if the connecting rod pin is sloppy or part of a piston skirt is damaged. I had a 98 Durango but can't remember if you have hydraulic lifters. A bad lifter can also emit a knock. If you have more of a clatter check the rocker arms. It's also possible a pushrod is bent. Use a mechanics stethescope or metal rod and try to isolate the noise source. The precise location of the knocking will improve you odds of solving the problem.

Loud knocking coming from the bottom end and now loss of power sludge build up i have changed oil normal every 2500-3000 miles with synthetic and slick fifty.

the engine probably has a bad bearing in it.oil sludge can be caused by short trip driving,overheating,pluged crank case vent or pcv system not working.the power loss due to the computer retarding ignition timeing due to the knock sensor producing a signal from the engine knock.regardless an ongine ocerhaul or replacement is neede.
but first make sure that the bell housing bolts,torque converter bolts are all tight.
make sure the knock isnt from the catalytic converter
check for dents in the oil pan
check engine accessorys for noise such as water pump.power steering pump,alternator,a/c compressor.and all attachment bolts

Check gages light came on driving a 2002 dodge durango now engines knocking

with engine running check the oil pressure gauge. if it is not reading you will have to check the pressure with an external gauge. the sensor on a v8 is locaterd rear of the engine next to the distributor. No oil pressure will starve the engine of lubrication and cause damage resulting in the knocking .
