To take all guesses out of the situation pull it apart and measure your piston to bore clearance, measure to see if the bore is out of round.

btw, you wont get a good gauge at whether or not your valves are leaking with oil, your best bet is using carb clean, brake clean, or even gas, dump it in the intake and exhaust ports and see if it seeps through.

My bet is the bore is out of round. even though its new, it should not consume that heavily.

btw, was this machine sunk? if so, you could have grit in the bottom end causing the premature failure.

Jeep, make sure the cam followers are in good shape and one of the push rods aren't bent too. thatll make er chirp.

before you try to replace the head, take it to that machine shop, let them do a full rebuild. or at least cut the seats, 3 angle valve grind, and check the guides.

this is what I do with every rebuild to just cancel out the chance that I would need to tear it down a second time. cheap insurance in my opinion.

hey cheap fix! good to know you didn't have to have it rebored.
