let's here it, who has blown up their stock Ls7's
How many miles were on it? What was the reason it blew if you know? I was told that there are a lot that never mention or post their story.
Just wonder if its a big number.

2007 Z06 with 5,800 miles. Oil starvation fried the bearings in the connecting rods. Prior to that I had two rocker arms fail and the needle bearings were found on the magnetic drain plug.

Blown engine
2007 z06 19,000. Miles dont knoe why it blew but believe thast a valve bent them trough a rod through the side of the block theres a 1 inch hole near the bottom of the block prior to thid they changed the rocker arms in the same cylinder to quiet the ticking sound which sounded like the lifters . I go to court on may 27 for lemon law cause they refused to fix the engine

Yes, I was pulling 1.3 Gs at Moroso in the left hander. For some reason the LS7 suffers oil starvation at high G in L handers
Katech has just finished rebuilding my engine w a racing oil pump, pistons, and other tasty bits with this and my new Lingenfelter sump the oil starvation issues should be over now
Cant wait to get back to the track

2006 w/ 5k miles
1st motor - Oil starvation (long, high G left hander) R6's W/ full suspension.
2nd motor - Thought it was oil starvation again W/ ARE upgrade but ended up being loss of oil due to cam and lifters.
Car only see's track time, its back together now and planning another track day in May.
It better stay together this time!

Mine was an '08, 7K miles, totally stock, oil starvation. Bowling Green replaced the motor under warranty, but would not disclose the results of the engine analysis. This occured in May, 2008. Eight other ZO6's were in BG awaiting replacement motors at the time.

I know of 4 LS7s that have blown here in the area. One was a '06 three were '07s.... all were from a broken valvespring and subsequent dropped valve. Ironically my 100% stock '06 Z broke a valvespring at 14k miles and because I knew about all these other incidents, I shut the car down before the valve dropped!!!! Saved my motor!!!!
I posted it here when it happened....

Sorry, you'd lose. .05% is 5/100ths of 1%, or 12 cars (rounded). The number is higher, trust me on that.
