I just bought a 93 civic and it now has a rod nock. I pulled the engineand discovered it has a spun rod bearing. there is little to no damage or scarring. I just bought new acl main and rod bearings, my question is do i need to get new rod and crank or do you think i would be able to get away with using the same parts


I also got new oil and water pump, timing belt and tensioner and all new gaskets

 

I would recommend getting all new rods and crank.

 

Get new rods and crank. Unless you get really lucky you won't be able to use ACL bearings. YOu can try to find a matched crank/rod set that has normal clearances, and also fits your block using ACLs. Otherwise you'll have to order custom matched bearing set from Honda, plastigauge to make sure they have correct clearances.

 

If you spun a rod bearing, chances are the crank is shot too. Only way to tell for sure is to measure it. You could always find a cheap used single cam and put all your new parts on it.
Im sure some of the local speed shops have some laying around...
