Red check Gage light on oil gage went all the way down.oil is full made a light nocking noise.still runs but makeing nocking noise.

Knocking noise is not a good sign. Could be the oil flow has been disrupted. Continued driving could damage the engine. Take it in for service immediately.

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.

We understand that your problem is: ok i have a ford sohc escort when you start the car it nocks like hell it started doing this out of the blue i drove it the day before and it ran great the knock is...

Hi there? check the oil level. if there is no oil in the engine, it will make it nock especially at the top end.
If the oil level is ok then start the car and remove the oil top up lead and check if there's any oil coming up to the top of the engine. it should pray oil out of the hole. good luck..

Engine noise and fails to start

check your oil. If it is frothy or gray then you have water in it and that means you have a blown head gasket. If there is oil in the radiator then the same holds true.

The nocking could be from a failed oil pump as well. If the oil pump fails then the car will not start. You have to remove the oil pan to replace the pump.

Trying to figure out where the knocking is coming from, on engine

It all depends how loud the knock is. A tapping valve can be caused by low oil level, or dirty oil. Topping up or changing oil will solve the problem. A really loud valve tapping is abnormal. Cars sometimes make what you call a spark knock when accelerating hard. Extremely loud knock coming from deep within the engine is a bad sign, which means the engine has failed. Further examination would reveal metallic residue on the dipstick.

Nocking when cold then goes away (Proton coupe )

It sounds like you may have some sludge in your oil. When the engine is cold the oil is thicker and takes a while for the oil pump to pump it through the engine. The next time you change the oil. Do an engine oil flush first to clean the inside of the engine and ports. If this does not work you might have to have the oil pump checked. There is no need to worry as long as you have oil pressure and the knocking stops. I hope this helps. Don't forget to rate this answer.
