rod failed? or did it?

[grumpyvette]

I see rods and rod bolt failures blamed frequently when engines self destruct at high rpms, but its NOT always what it at first might appear to be....are there any detailed pictures of the rods or rod bolts that failed??? in many cases the source of the problem can be seen with a careful detailed exam, if you don,t know the SOURCE of the problem your doomed to repeat the sequence... and keep in mind a good deal of what might appear to be rod/rodbolt failures, are ACTUALLY the result of over reving the valve train,and loss of valve train control, OR detonation, theres no way to compress a bent valve or broken piston ring land without potentially damaging the rods

I've only seen shear enough time to recognize it but many of those conditions were unfamiliar to me. Very interesting reading. Thanks, grumpyvette!

ARP should steal a page from Packard's advertising book... "ARP- Ask a man who uses them!"
