[QUOTE="JonV, post: 147513, member: 24509"] what is the most common failure mode for a big end conrod bearing? we just had a brand new crank installed, and only got 4 hours out of it! prior to this we lost the original crank to the same failure, but no upper end damage. in this case it appears the crank migrated to one side (to the right) until it contacted the case. piston skirt is seized and plating damaged at the finger. (to replace or rebore, ah that is the question) could not find any contamination in the intake tract at all. we have not changed anything. did plug readings at mid and top, both excellent. no breaking up during operation at all. 32:1 maxima superM, sunoco ultra 94 (same for 2 years) dont want to lose another! thanks, [/QUOTE]
