I'm not sure if I need to start a new topic for my etech project, but I have another question and can't find many answers for it in any search. How can I tell if the wrist pin bushings are bad? This is a high mileage truck, 1.8 million, and I don't have any history on it for the first 1.6 million. The bushings are copper colored. Is that normal, or does it suggest high wear? The manual says you need a special press and broach to change the bushings. Is it possible to change them without these very expensive tools? New rods are much cheaper than the tools, but still $400 a piece.

I always take connecting rods to a good machine shop. Im not sure if you have one local to you, but when putting new bushings in the small end of the rod, they need to be machined and sized to fit for proper tolerance spec to the wrist pin. The wrist pin bushings are bronze and need to be pretty precise.
