Hi Jay -
"Ah ha! And I assume that's why the oil pressure relief valve was jamming. Well, a total rebuild is the worst case outcome, but at least you have diagnosed your problem."
Yes. The PRV and all the bearing shells are scored. One cam bearing cap was missing bits from the working surface and had voids or bubbles in the metal. The filter pleats and sump oil had little bits of aluminum.
"Those modifications won't turn your S3 into a rocket ship, but given that you need to pass emissions, it's probably all you can get away with."
I'll be happy as long as there's a definite increase in pickup.
