ok i got a b18a for free but the thing was that it was run without oil because of a dented oil pan that smashed right up to the pick up. so i took it all apart to find 2 rod bearings all messed up and 2 of the main bearings. the crank is gone already and 2 of the rods are gone. the main bearings never spun but they did get eaten up till the copper ? was showing but it never actually did eat into the block itself.

so i am wanting to build this block but i was worried about maybe like the main caps might be out of round or widened or wrapped because of the heat generated and all that.

what can i do to make sure the block is all good and i wont waste my money building it

 

take it to a machine shop. if anything is slightly warped u could always get it line bored
