In my bro's 00' Ws6. Car starts right up and oil pressure goes right to 40 psi, but there is a real bad squealing/screeching noise coming from the motor, no knocking. The motor will not keep running on its own, give it a little bit of gas and it will stay running. I took off the belts. Restarted the car and still has the noise and dies. No check engine light adn no codes. Pull the valve covers to check for a cracked valve spring or a dropped valve. They all seem to be just fine. I am thinking maybe a spun bearing somewhere.

Anybody have any ideas before we pull the motor?

Does it have any mods? auto/m6? Is the noise from the front or the back.

yea, lots of mods

Trex cam, ported and polished 243 heads, 7.400 chrome moly pushrods, prc dual valve springs and titanium retainers, ported fast 90 intake, pulley and long tube headers. Also has ARP Rod bolts and head bolts. The only part that has maybe 10,000 miles is the cam. All the other stuff is new. Just finished the car up a few months ago. Car is a m6 with a ram twin disk. Sounds like more towards the front but hard to tell, loud enough to hear inside the car with a open borla and no cats.

Loose crank hub/dampner possibly buy an ARP crank bolt and retighten it

who put the rod bolts in? possibly installed incorrectly to allow bearing to run loose over time?

Main bearings will sometimes squeal after they spin because they get no oil..... Check everthing else first...

drain the oil, see if you have any bearing material in there..

Thanks guys I will check everything out. I will check for the loose crank bolt. Tho I am leaning towards a spun bearing somewhere. The car starts right up but unless you give it some gas it will just die. Motor seems like it is going to lock up soon.

I did the rod bolts and did everything according to what ARP told me to do. I will do some more investigating but will be pulling the motor.

Cut the Oil Filter open and see what you find. Use a flashlight to see if there is Bearing material.

I had a motor do the same thing and it was a rod bearing. The squeal sounds like death. LOL. When you drain the oil, if it is a bearing, you will see it in the oil and in the filter. I have also seen an intake gasket make the same noise. I know it sounds crazy but I have. It was a high pitched whistle/squeal that was being caused by the air being pulled into it.
First thing I would check is for metal shavings in the oil/filter

Will do. I have never heard a noise like this before, lol. Definitely sounds like death.

I appreciate all the responses and suggestions from all of you.
