Engine loud, no oil

[E.Murray]

I bought Ty 0907 from a member. It has a McCoy Supermotor with about 4k miles that he sold to me as junk. I was going to pull it and see what was salvageable, but thought I'd post the symptoms here first just in case.
He was running it on the highway when the engine got very loud. He shut it off, coasted to the shoulder, and trailered it back home. He was thinking exhaust leak, so he pulled the headers and sealed everything up. Tried to restart, but it was really loud still and the oil pressure gauge was pegged high. In troubleshooting, he pulled the valve covers and there was no oil in the top end. :tdown: He'd been messing with the truck and sinking money in for 10 years and finally just gave up (and gave in to his wife...). Is there anything I should check before yanking it?

By "loud",do you just mean the exhaust is loud?

I had a basically stock rebuild McCoy motor and my exhaust would constantly separate from the down pipe (it just had a little band clamp holding it together) finally I just welded it up.

I don't know anything beyond this. It has headers, a pte60 turbo with 3" down pipe and it seems solid. Plus he had to pull it off to redo the header gasket.:dunno:

Thrown rod?

Re: Engine loud, no oil

I'd just pull the motor and check it out.

Re: Engine loud, no oil

test it with a real mechanical oil pressure gauge and go from there.

Re: Engine loud, no oil

Define "loud." But before you go any further remove and cut the oil filter. Full of metal? Which I suspect it is then pull the motor and do proper rebuild.

Re: Engine loud, no oil

Unfortunately, it has fresh oil and filter (one of the things he did during the troubleshooting process). I wish I knew more about what happened - like what exactly "loud" means. I'm not going to try to start it for fear of doing more damage. I guess it's coming out...

A pegged oil gauge, stuck oil pump or broken one

It's doubtful you can do any more damage than already done, just starting it and letting it idle to find out what is making the noise. I would probably pull the valve covers and have a look, before pulling the motor.
