If you had 0 oil pressure driving that 5 miles, and it was nocking, chances are it is not going to go away, the damage has already been done. the only recourse here is total rebuild or replacement of engine or the very least rods and main bearings if it did not scar the crank, you might get away with new bearings. only way to know for sure is to drop pan, and wiggle rod cap and see how bad it is. , you will know when you find the bad one it will be looser than the rest. as far as the mains are concerned you have to take each one off to see if there scared. i guess the bottom line here is what do you want to spend, either way it not cheap.

Oil pressure problem


210K Miles?
Knock for 40K Miles?
Suggest its time to replace the motor.

I would not have flushed the oil with that many miles; but you might have them change the oil and filter with a heavy weight oil if you had 5-30 try 20-30, if you had 10-30 try 20-50.
Stall after the oil change can be a co-incidence but check something was not knocked loose.

I went to drive my 2001 pontiac grand am se and the low coolant light came on, i was not even a mile home so turned around , pulled into driveway oil light came on i shut car off open hood and oil w


make sure your plastic coolant container mounted on inside right fender is at least half full. Keep your eye on the temp gauge and make sure the car doesn't overheat. These sensors are very touchy and sometimes cause a fault when actually there is no real problem. Also make sure you didn't knock loose the oil pressure sending unit connector, located near the oil filter. Happy Motoring!

Replaced the head on the motor...250000 miles on my daughter's 1999 Grand Cherokee..now the mechanic says that he hears a knocking under the motor says she should just get a new car. Could the knocking be...


Lets review.
Replacing the head at 250k was probably not a good investment.
My advice has always been, if you need engine work at 200k or more, its time for another vehicle because the rest of the parts are still worn out. The normal life of a car or truck in the USA is 200k.

Usually a knocking sound means a rod or main bearing has failed. Which would require an engine overhaul to fix.
Black oil has nothing to do with the pump. The oil should be changed at 500 miles to remove any debris caused by replacing the head. That may fix the problem if there is junk floating around in the oil pan.
If the oil pump has failed, you would have very low oil pressure which would show up on a gauge.
It could cost you more to fix the knock that it did to replace the head.

Knocking and clanking under hood of 2002 Ford Escape. Oil light has been flickering for some time now but it has oil in it. On my way to work it started making a horrible noice about 1/2 mile before I...


Could be the oil pump but it could be the crank bearings are so worn that you have no oil resistance causing intermittent low oil pressure.

The pan on the bottom of the engine needs to be removed to access the oil pump and that could be a job but it sound like you might have some serious engine damage. This vehicle needs to be diagnosed by a qualified technician to ascertain the viability of the engine.

I think oil pump went out, is ti inside the oil pan?


This should be the oil pump. Do not attempt to start or run vehicle. It will cause engine damage.

Make sure there is not a problem with what drives the pump either. It could be gears etc.

I'm not sure about yours, but on many vehicles, the oil pump is driven by the distributor shaft.
