wrist pin variance of 30 grams
I had assumed that my piston wrist pins would be pretty similar and close in weight from one to the next. Nope.
pistons removed, cleaned up and wearing their new rings weighed much closer to one another. All within 2-3 grams.
Not sure why the wrist pins have such a large delta. THere are a few different numbers stamped on them, so maybe the experts will know something more. Pictures are below.
Should i try to drill/grind/machine out up to 29 grams from these or look to replace?
