Arp Manufacturing
Has anybody ever sent arp any bolts, that flew apart for them to check out? I sent my arp rod bolts, i believe they where not torqed properly. They have had my parts (piston, rod and bolt) a couple months. I hope they send me notice that the bolt was not installed properly, then i am going after the shop. Ken

Perhaps Nuts were torqued, then Rod bearing wore & spun, then rod nut got loaded. Bearing wore more, Nut unloaded and Lost torque. Possible for Nut to spin off and got to pan unscathed.
Happened to me 15years ago. I over-rev'd the 455.  HIS

I've got paper weights like that! Anyway, would have to agree, looks like the bolts held & the cap came apart. What did the big end look like, discolored? Bet that boogered the head. I'm still trying to think-out how/why the piston came apart. Do you have a better pic of the piston/rod, like maybe from the side? What were the circumstances when it came apart, high rpm?

Well i got a verbal from arp, he said the bolt was definately not torqed properly. I ask for a statement in writing, he said he would talk to someone else on that. They probably wont want to slap a hand that feeds them (the machine shop), hopefully they will help me out, maybe i shouldnt have said a shop did it, i did not give no shop names. Ken

If you want it done right, um, how does that go again!?! I learned the hard way, and do all assembly myself. Always check machine work & tolerances. It's not that a shop is particularly good or bad, it's just humans make mistakes, can't (always) fault people for that. Not sure if pointing a finger will help either, but may make it so you can't use them again...

I dont know enough about engines to check out things (I build houses not cars), so i hired a shop that was suppose to know what they are doing and stand behind there work, so they didn do it right or stand behind it, so i have to get experts and possibly a lawyer to get it done right(but not by them, i wouldnt take my motorless wheel barrow to them, which i shouldnt have to do eighter. People do make mistakes, I make mistakes, but make em right. Ken

Thats what i am doing, letting it go and chalking it up as a learning experience. The cost of going after them was getting more than my loss. I will just keep bad mouthing kammer and kammer of huber heights, ohio.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
