2001 jeep grand cherokee engine knock and no oil. Added oil and still knocking. Was told I need a new oil pump. But if the engine is knocking is it worth it to replace oil pump.

How long were you running the engine low on oil? It might not be worth it based on internal damage. You would need to have a local mechanic look it over for you on how bad the noise and damage is and you might be looking at a complete rebuild or replacment.

You imply that the knock was caused by "no oil"- so what the knock is- could be bad-if it is a rod knocking your engine will need a complete rebuild- might as well just drive it- "KNOCK-KNOCK" "Who's there?" "OIL" "Oil who?" "OIL I ever wanted was a little maintenance!"

I think that next time you buy any vehicle you should know how to take take of it no oil means bad news i would like to see 1 engine that runs without it . You should check oil every time you put gas in but i think it is to late for yours . You might find a dummy to take it off your hands if it even runs good luck
