Here's my dilemma. Cruising down the expressway one day cruise set on 70 miles per hour. My engine starts skipping built motor custom twins as in my signature. And acted as if it may have popped a piston or I lost an injector oil pressure is perfect truck runs fine just skipped. So I park it after I had it towed home about 20 miles and finally get around to pulling the motor just to refresh it make sure it looks good everything looks perfect. Get to the lower oil pan pull it off huge chunk of Steel in the bottom. I said okay not good pull upper panf the connecting rod at the big end was torqued to the crankshaft. The Piston was just sitting in the hole with the small end of the rod still attached. This didn't happen under power truck may have had 3500 miles on the new engine. It happened with the cruise control set at 70 miles per hour no damage to the crank all the bearings could be reused. The connecting rod did bust 2Pistons but one rod 2 Pistons would half-ass fix it but I'm not doing that it busted the skirt off one of the cylinders which good we've got buffed out but I'm not risking it. sent rods back to Crower cam cams in California been there for 2 weeks without a word what do you guys think my chances are for them paying for this s*** because it ain't no Builder error here. Lol. jk. That was a speech-to-text so disregard any of the poor punctuation I'm driving thanks

Need more info and pics.

You said crank OK so I'm assuming big end bearing did not seize to crank, what about small end (is it stuck on wrist pin)? Even if the small end seized I would think the piston would have been destroyed before the rod broke in 2.

If neither end seized and it broke apart in 2 pieces with minimal collateral damage, I'm would have to say it was a defective rod (probably 1 in 1 million or more).

Interesting what you find.

i wouldnt plan on crower paying for your rebuild. you might get a new set of rods but thats probably as far as i see you getting anything.

I had one come apart and I found another with several stress cracks. Only 2 were straight as well

I can text pics if someone wants to post them

Wow two instances where rods come apart without a particular reason behind it??? Sounds as if there may be a case to force Crower to step up. I realize competition parts rarely come with any guarantee do to the nature of the Beast, but come on a competition part that won't stand up to mundane use???? If I were building what I wanted to be known as a race winning reliable competition part I sure as hell wouldn't want it out there that it wasn't standing up the regular use. I think you should both get together and push the issue, the only sure thing here is if you do nothing nothing will happen. The worse thing that can happen is they tell you to pound sand and that may not be in their best interest.

I'm just gonna push my stock bottom until I can get carillos, it's a shame this stuff cost so much and it seems like most of it is still a gamble. Makes me wanna run an ls powered rig until this sport isn't such a risk.
