Ok I was doing the DX 1.5 DPI to SI 1.6 MPI swap on my CRX and I figured I would just put in a stock 1.6 engine first before I upgrade to something bigger. Well I bought this engine from a guy and dropped it in. Got it running only to find it had a knock!!!! Anyways I traced it to the number one cyclinder, pulled the pan bearing cap and found the bearing was spun. So now I am wondering how much this guy beat the crap out of this engine to get it to spin a bearing??? AND HOW LONG IT WAS DRIVEN WITH THE SPUN BEARING. The crank is worn but still within specs. I have seen alot of Hondas, but never a spun bearing. SO WHAT TO DO NEXT??/ 1. Can I just get by with replacing all of the bearings?? I mean I gotta buy a whole set anyways, might as well change them all. Pulling the crank and having it reconditioned would be about as costly as finding another engine. 2. Should I replace the oil pump??? Would a spun bearing draw cause to replace the oil pump?? 3. Should I just look for a new engine since this one probably has already had the crap beat out of it??? Any info or advice would be appreciated!!! I just install em' I don't usually have to rebuild em'!
