I know there is "common knowledge' on this subject, but fact is I've had
used oil coolers since I was a teenager on all my projects and never had an
engine problem result from that. I couldn't afford a new oil cooler for
every English rotter I got in those days, and a cooler was mandatory for the
SoCal summer temps. Rinse it out with a slug of gas, drain it well, and
leave it in the sun for a hot day or two to dry out the gas. Obviously, if
the crap that comes out in the gas looks bad, rinse it some more until it
doesn't.
Sacrilege #2, I always re-use the head studs and rod bolts and have never
had a failure. The only time I did differently was for the turbo sprite
motor that got brand new ARP studs and bolts.
If you're going to race the motor, all bets are off. But for a street
motor..........get real(and tight)
