thanks for your response
can the oil cooler cause antifreeze to leak into the eng
thought it was just the other way around from what i read
i can see with the exhaust off dscoloration on the valves on cyl #1 & 5
im sure the engine overheated since the right front cooling fan was dead
could i get lucky and it just be the heads
if its in the cyl wall should one have it sleeved
only 21 k on the car
it is worth fixing
your thoughts
thanks

Yes, the oil cooler can leak coolant into the oil; when the car is shut off, the cooling system is still at 18-20 PSIG, while the oil pressure is zero.
You can do a leak down or bore scope the engine, but I still think that if the cooler pressure test OK, it needs to come out an apart. You would not only need to find the source of the leak, but carefully look at the bearing and journal surfaces; these cranks cannot be cut, and there are no oversized bearing shells available, so it the crank is damaged, it has to be replaced.
LN Engineering makes excellent cylinder liners for these engines, so if a wall has failed, that would be the way to go. If the head is cracked, it may be saved by welding, but that has to be examined on a case by case evaluation.
