Good morning folks.

Been like 12 YEARS since I've visited here, but the '80 4X4 20R's been running great since the rebuild back then.

But now, it overheated and then sat for 6 months, waiting to be repaired. An insidious pinhole leak in lower radiator hose occured, so no smoke or even smell. Just an almost unperceivable decel on I-5 with no accelerator pedal response. That's when I noticed the pegged TEMP gauge.

No oil or coolant was drained during this time, and the oil/coolant mix really damaged the cylinder walls and pistons.



After a hard time removing the pistons, and doing some initial light honing of these .50mm oversized cylinders, there's unacceptable gouging in a couple sleeves, #4 being in the worst shape & #1 being the best.

My question: What's normally done here to reuse the block, considering damage such as this? I ask because I really don't believe going to .75 over will be enough. Hopefully it will, but if not, What?

Thanks for any comments.
Steve
