JDM B18C Rebuild

Engine had 180psi cold compression. I just rehoned with a flex hone. Do you think the vertical marks are really bad? I also had metal debris on the piston walls. I filed the side of the piston? Think this is okay? Let me know what you guys think. Thanks.

Re: JDM B18C Rebuild

Machine shop, bore and hone to oversized and hope the vertical scoring comes out.

Requires new pistons prior to handing to machine shop so they can bore and hone to the new pistons.

Probably will have to go to max oversized.

Re: JDM B18C Rebuild

Thanks for the advice. I was really hoping I could get away with the scoring. I know I could, but I would probably get low compression numbers and have blow by. Thanks.
