looks like a few, all on the same side had issues. the #8 had the hole in it, then 6 and 2 had cracks, that extended outside the bowl but very fine cracks. #8 did the deal in no doubt. this motor smoked white on fire up since i got it, but i thought it was from the fuel distribution block, the way my motor with 60's and the elite pump fired white on startup. i never smelled the smoke from the ipe at startup because i didnt think this was an issue. like i said, im betting this motor was hurt from the get go. tadd said he hammered it pretty good for a while, but never saw any signs of an issue. i highly doubt he would put a motor in my truck that he thought would be an issue. e doesnt like dealing with me when im pissed.
