Question about 2001 Chrysler Concorde

Oil light on when car reaches operating temp then engine knocks

When car is cold, you hear a little ticking from the engine but car runs fine. When car reaches operating temperature, the oil light comes on and car starts to surge. There is a terrible knocking sound coming from engine and car eventually dies. All fluid levels are fine. The engine light does not come on during this time. Car was hooked up at Autozone to get a reading from computer but computer registered no problems. Was told it could be oil pump or sensor, but sensor should have tripped the engine light and registered on the computer. Car has 150,000 miles on it.

    As stated in this posting, I have the same problem! When first started, the engine seems to run fine. Once, up to operating temperature, it begins knocking and when idling, the oil light flickers on.

    I tried to Seafoam the problem, but no results from that.

the one thing in your statment is the knockes/knocking this what is known as the big ends and indicates the engine is under pressure and needs a lot of repair.If when you start the engine when cold if you stand at the back of the car and if the smoke coming out of the exhaust has a blue tint/ie like a old ladys hair tint ,as im sure you will see.[bottom line] the engine needs replaced.adrian,,,,

I get a clunking noise from the front of my truck when I cold start it and only for a few min as is warms up then it goes away. This started in cold weather 35-60F. I have a chevy silverado 2001 1500...


this engine has forged pistons whitch expand more than hyper-u-tec-tic pistons when heated . this is normal for this engine . my brother has a chevy silverado 2001 1500 4.8Lwith 650,000 kms and he said his made that noise when it was brand new and the dealer said this is normal. the truck still runs like new with lots of power and it still makes that noise before it reaches operating temp then goes away.My brother uses lucas oil treatment and it helps quiet the knock a little when cold.

Engine knock hard over 2500 rpm


Does the oil light come on or the knock occur during the engine warm up after a cold start?
There could be a couple of problems causing the issue. You could have an oil pressure pump or pump pressure regulator sticking. I would have a mechanical oil pressure gauge installed and verify oil pressure at idle and 2500 rpms to make sure oil pressure is in normal ranges.
You could also have excessive piston rod bearing, crankshaft bearing or cam shaft bearing wear that will cause oil pressure to drop too low to prevent the rod knock your hearing at 2500 rpm.
You said a knock and not a ticking noise,so I don't believe a lifter is the issue at 2500 rpm.
Start with the oil pressure check and go from there.
Let me know.

Oil pressure light comes on intermittently, often after getting up to normal operating temp. Goes off when engine revs. No knocking, runs fine, oil changed...still comes on. 160,000 miles.


try running a higher viscosity oil.
Instead of 5w30 (W stands for winter or cold viscosity) try a 10W30 or maybe more like a 20W50 the higher number is when the oil heats up.
You may try and add a can of No-Smoke or STP oil additive since you recently changed oil.

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.

Knocking under valve cover on cold starts


Is there any smoke when you first start it? what is happening is the valve seals are probably worn and letting the oil seep past them. when your engine is first started it has no oil or very little oil at the top of the engine, thus causing the knocking noise. could be more but this is a most likely answer. oh and is you haven't changed your oil every 3,000 miles you had beeter start doing it.... answer knocking sounds usually come from bottom of engine try a better quality and correct viscosity oil
