I have these wrist pins for a stock 2.0 six cylinder motor. Most of them have a slight etching to them. I'm not sure of the history of the motor so I don't know what might have caused it. I suspect water. Does anyone know what might have caused this? Should I continue to look for replacement wrist pins? Or use these? They can be slightly felt with a fingernail.

Could it be from water/moisture acting as as an electrolyte and the two dissimilar metals acting as an anode and a cathode? (Tool Steel VS Aluminum?)
This kinda makes a battery of sorts. Usually the aluminum turns to shit first as it breaks down faster. The wrist pin damage could be from this galvanic action. Ive seen that before. I just can't remember what the hell the outcome of the research was... JeeZzz i'm getting old... Twystd1 |
