Recently bout three months my engine oil light

When an engine oil light comes on, this is the 911 call to you that your engine is having an emergency in that there is not enough oil to lubricate the moving parts of the motor that keep it operating. Those knocking noises that you heard were the dying breath of your once dependable Ford engine; which is now junk. Because you "didn't have the time to pick up oil", you will now have to find the time to either replace or completely rebuild the engine. The Expedition has a V-8 so expect to pay at least $3500 for a new motor.

I have a 2000 Ford Vrown Victoria 4.6 liter.Starts and idles fine, engine knock starts when reving or accelerating, performance is unaffected, Any suggestions for a ressolution.

Have you tried premium fuel? If this cures it then its just "ping" or "spark knock". Have you checked the oil recently? Make sure its full. This could be serious but is hard to diagnose with out hearing it. Hope this at least gets you started.

My engine has a knocking sound

i'm sorry! does the engine dipstick for the oil,is it full? has it been run low on oil lately? is the knocking sound like a real hard knocking,thumping with like deep base sound?if so,do not start it again. you may have a bad crankshaft bearing,or a bad crank,broken crank. if it's a tapping sound,that's different. it could be low oil pressure, just like the lower knocking,it may be bad oil advice is this, lower knock from oil pan where you drain the oil,do not start! upper,on top of the engine,just change oil 1st add a fram oil filter,if in cold weather recommend 5w30weight oil,in summer,30weight castrol with fram oil your oil light on? if not,then it'not low on oil,but CHECK your oil on dipstick,just to be sure thank you for choosing

No oil Pressure, with knock.

The first thing I would do is change the oil filter. Also, what engine do you have.

Air conditioner knocks when turned on at low rpm

The a/c compressor has an internal failure .
Most likely will have to replace the compressor and recharge the system. The drier is also going to have to be replaced because the system was exposed to the out side air.

Ford Expedition 2000

Good Day Tony,

That's an intersting problem.... I would assume that if it was misfiring in a cylinder it would trip your check engine light as it did before. Because it only happens when you are going 50 it might be something else. What happens when you put the truck in park or nuetral and rev up the engine? Rev it up slowly and see if jerks or hesitates at any particular rpm range, I'm just trying to rule out if it's a possible transmission problem or engine problem. Let me know and I can assist further.

Good Luck
