#1 piston and wristpin bushing
You can see but not feel these lines in the bore and on the piston skirt. These are at 0.0035" clearance (if the machine shop did what I asked). Now, the question is, is the clearance too tight, or did the piston rack back-and-forth too much because of the failed wristpin bushing?
