The screeching is probably the starter and flywheel skipping on each other.

How much was oil was over filled ? if to much then would have been drawn into engine block , drain the coolant and check for any contamination, also would have got into the clutch mechanism , that could be the screeching , i would expect will need a new clutch at the very least , hope this help

Hi Bill 609!

Definitely sound like a rod insert to me. With my practiced ear, I cna tell the difference between a main bearing knock (deeper sound, more of a thudding noise), rod bearing knock (not so deep, gets louder as the engine revs, kind of a rat-tat-tat-tapping noise), and a wrist-pin knock (not quite as loud or deep and gets louder with decelerating RPM).

You can tell which cylinder the knock is on by removing the spark wires to each cylinder one at a time while the engine is still cold enough to knock. (Don't get shocked!)... when you hit the right one, the knock will noticeably quieten or possibly quit altogether!

The 300 Six is a tough old motor and I have seen them survive for years with rod knocks... Just allow the engine ample warm-up time before driving, drive on the conservative side, and keep an eye on oil level and pressure.

An oil and filter change to a higher viscosity oil with a can of STP Oil Treatment (Or something similar) is a good band-aid fix for now, I would recommend Castrol GTX 20/50w... in my opinion, Castrol is the best brand out there, I use it religiously - - - I have a customer with a Chevy Suburban who has followed my advice and adhered to good maintenance discipline that has racked up over 300,000 miles on the original small block and no consumption or engine issues, and is still running strong!

Bill, the temporary fix will work for a while, hopefully a long while --- BUT when it reaches the point that the knock doesn't go away, it is time to park it until the real repair can be done --- otherwise you risk throwing a rod and destroying your engine beyond repair!!!

Please don't hesitate to post a comment or ask if you have further questions. I hope this information answers your question and concerns and wish you well with the Ford. *** And remember to rate my assistance... Your rating is my only compensation for helping you in the free blog!!!***

SOURCE: 1999 Ford Windstar. engine stalls.

You know, lookinig at this problem more, you have more possibilities of what may be wrong:

  1. Your idle speed may be incorrect
  2. Fuel filter may be clogged or water and impurities in your fuel system
  3. Possible damaged coil pack or wires
  4. Emissions sytem components faulty (a sensor, catalytic converter, muffler, etc.)
  5. Faulty or incorrect gapped spark plugs
  6. A vacuum leak at the intake manifold or vacuum hoses (check the hoses for cracks or damage)
  7. Fuel injection or engine control systems malfunction (ECM)
This should keep you least with the easy stuff to inspect.

SOURCE: Loud engine knocking on 2001 Ford Focus

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.

I overfilled my truck with engine oil and now it wont start

Since you have already set the level correctly lets get some more info.

How much did you over fill it? If it was significant, any number of mechanical components could have been damaged. Also what did it do when you ran it the first time? Run poorly? Start spurting oil from places it shouldn't? engine died?

In ascending order here is what I would do.

1. Make sure you didn't accidentally knock something loose when you corrected the oil level. It's easy to do when flustered.
2. If you have the tools just confirm the engine is getting fuel and spark. Quick check if you have the tools. If not, maybe skip this.
3. If it was over filled significantly try pulling out a spark plug and see what it looks like. If it's full of oil you at least need to clean the spark plugs and even then you may be in for a new engine. If it was overfilled that much and it pushed oil into the cylinders from the crankcase it's likely that internal components have been bent or destroyed.

Try starting now. If knocking still, turn off immediately. Pull the engine oil dip stick with the engine off and check the oil level. If a foamy brown fluid (or droplets of water) is on the dip stick and it appears overfilled then water got into your oil and may have damaged the motor. You may be lucky if you have the oil/water mix removed and fresh oil and filter installed. Try running then and see if any better.

Air Conditioning not working properly

My wife once mistakenly topped off the tank with diesel instead of gas. Same symptoms. Gas also goes bad when it sits in a tank for several months without a stabilizer. Try adding a fuel stabilizer and filling the tank with high-octane premium gas.

I took my car to a mechanic because the low oil light was on. He added oil and 7hrs later when I started the car it was knocking. If he added to much oil and the engine was cold that was why it was...

If he is any kind of mechanic he will know that adding too much oil can bust a gasket because of the pressure. If it was not knocking before take it back to him and tell him about the new problem after you left his place.

My 04 Town & Country has a loud Knock in the motor

Why did the engine get hot? Coolant loss? Was the oil level too low before more was added? If it was low, how many quarts should have been added? I believe you have serious engine problems. Too much oil is as bad as too little. What happens when it is overfilled, is the oil 'foams', causing a lack of lubrication of internal components. Oil in a foamy state will not lubricate properly. I believe what you hear is a crankshaft or rod bearing that is now damaged. If I'm correct, you need to replace the engine. Sorry for the bad news.

Over filled with oil. lifters knocking

You will get low compression and oil will blow-by and cause a smoke storm cloud behind your truck.
You can get a fluid pump to pull out excess oil through the dipstick.
same happened to me, truck is tough and bailout needed :)
