So...i'm posting this under the clone heading, but it's an issue with the predator as well. i built two new engines at the start of the 2014 racing season. both were built using stock side cover bolts. although the bolt issues have been hashed and trashed on here, this isn't about the bolts, but about the blocks...in particular, the top two side cover bolt holes in the block.
we bult the motors and torqued the side cover bolts to 17ft-lbs. after a good run, we had to pull the engines down for checking and other issues.....but we found that the top bolt holes on the block, in particular (looking straight on at the block from the side cover side), the top bolt hole on the right was cracked in my son's hemi predator block and the exact same hole was broken in my clone (the piece was laying in the bottom of the crank case).
has anyone else had this happen and if so, what did you do?
for me it was a little jb weld on the stud (we swapped the bolts out for studs) and run it down snug and let it cure...no issues....for my son's block, we are going the same route, but having a friend look at it to see if he can weld up that area.
if it was just a clone or jsut a predator, then i could say that it was just one of those things....but two different style and make of blocks having the same issue? and they were built at the same time and all the side cover bolts on both engines were torqued the same.....
any idea's or suggestions?
