Ok, The CRX is off the road ( Boosted B18A ) and the engine seized this summer while I was driving slightly after hearing a rattling noise from the bottom of the engine. I am assuming it was a crank bearing going bad. This was just after the engine severely overheated earlier that day without me knowing. If the problem is a crank bearing that got jammed, is it possible to find out and change this by removing the oil pan and head? Winter is almost here, and I'm trying to avoid having to pull the engine back out again. I mess something up everytime I do that. Can I possibly change these bearings with the engine still in the car?
