It would appear that it might have something to do with the oil feed also?
I have been working with SCCA GP racer Jim Sloan this spring. He was
commenting that #3 crank journal is always the one that burns when he loses
a motor on the track. He quickly explained the stock oil flow through the
crank, then talked about the modifications he currently makes ( enlarged oil
passage in crank and journal bearing ) and went on to talk about the
possibilities of cross drilling the crank for still better oil feed.
Could any of this lead to burning up a piston?
