Curious case of the broken rod
I bought a '90 C4 cheap with what I thought was a thrown rod, but it turns out it was broken. The bearing surface is good, the piston is good (minus a chip from said rod), no valve hits, no bent push rods, no signs of water, just twisted and broken.
Any thoughts on what might have caused this? I've seen many broken engines, but this one has me scratching my head. It's a 60K car and other than the rod, the engine is clean with almost no wear.
Anyone got a good used L98 piston and rod? :-)

You could also add that water ingestion from driving thru a somwhat deep puddle coukd do the same thing.

..... Hydro-lock ... Nitrous backfire ... or a heavy dose of starting fluid with the distributor 180 or so out ... if the engine was running when that rod broke , it would have ventilated the block and oil pan .....
