The parts just kept falling off the C20 in an attempt to figure out what the problem was. First go round involved getting under the truck and figuring out why there was an oil pump and a bunch of rod bearings laying in the truck along with a pan gasket.
Well that would be because they had started to diagnose a rod knock but gave up. After checking all the caps for torque and throwing a battery on it, it would do nothing but click when trying to start, a breaker bar wouldn't turn it over either. So I whipped up some engine/bolt unsticker out of acetone and transmission fluid and filled the cylinders.
When that didn't work.......well out comes the engine.
And onto the stand to see what's up but first let's show the "rod knock" that these Chevies are famous for. They tend to bust up the flexplate if the convertor isn't shimmed correctly, happens quite often with crate engines.
It still wouldn't turn over with a breaker bar so I loosened all the rod caps and it would spin over, interesting. Next I pulled them one at a time and what I ended up finding is a few new bearings but the culprit as to why it wouldn't start again? One of the new bearings was .010 oversized which would lock up the crank when torqued correctly.
Finally, the reason this had sat for 12 years.
