I would suggest draining oil and inspecting it for debris, possibly even cutting the oil filter if you don't see anything real obvious in the oil. I would do that prior to running with any other gauge to try and prevent further damage if it's already hurt, may cost less to fix.

Thanks we pulled intake and vavle covers, and found metal flakes. needs rebuild or replaced. do you know if a 502 will fit in its place? motor mounts E.T.C.

Where at in Ohio?
Anyway, Dave will probably know more than me, but the 502, mounts and all should drop right in. I think the only differences between the MK 4, and Gen 5/6 engines is internal and maybe valve covers.
