Samcrac?? 😅😂😅😂

Greg didn't put the Texas Speed cam in there

@@bb5242 I was going to say, whomever tuned that car last is to blame for sure. With the cam, bet they raised the lmiter to like 7500 and it was singing well past its capability when it went boom.

And aside from possibly installing the cam in wrong, Greg didn't miss a gear and/or launch the motor or run the engine out of oil. Also, could have been retuned lean. A myriad of reasons the engine could have failed that had nothing to do with the integrity of the LS7 as it was built from the factory. People kill engines due to abuse more than they randomly fail. Most common failure is low oil level + high RPM. Mods can kill an engine too and tuning. When you modify an engine that has adequate power like a stock LS7 which is plenty on the street, be careful what you wish for. PS. Chris is very talented with wonderful temperament, methodical etc...all the right stuff including young and strong...but I cringe when I see engine work this extensive with nothing covering the fenders for protection. I know, he will run the orbital over the paint when all done but only takes one dropped wrench. Or...maybe the plan is a repaint. Paint doesn't look too bad to my eye but he may have other plans....from the peanut gallery.

@@lukewalker1051 nah. LS7 is simply junk like any other GM product. MOPAR or NO CAR baby!

LS7 exhaust valve seat wasn’t machined concentric to the valve guide thanks to Linamar Corporation who machined the heads for GM. Exhaust valve fatigues and breaks off. Destroys #2 piston and the entire LS7. That’s why I got both of my heads reworked by LPE.

Thanks man!

yep its the exhaust valves that are hollow and have the issue

Yep

It’s not the valve, it’s the valve guide and valve seat that weren’t machined concentric to each other. Linamar Corporation machined the heads for GM and their(GM’s) quality control didn’t catch it or overlooked the problem. Valve heads don’t fall off just because they have a hollow stem. They break off from contact with the piston, over-rev/valve float, or in this instance poorly machined valve seats that fatigue the valve stem.

@@natez0690 100% correct. That's the LS7 valving issue that these are known for. Though, most of the time, they only kiss the piston after the valve works its way to the point of contact. This one looks like it took the valve and decided to play dodge ball with the rods and crank at, or around, 7k rpm. That's a lot of energy transfer if things aren't working smoothly.

Obviously not a stock LS7 with a stage one cam in her.

Depending on the year its was a issue for the ls6. My 04. Is goin strong 130k

Knows What??? How to say Carnage?

Dont get too down. These cars are an insane value for the money. Won't be much that can touch it under under that 60k figure!

Was it all stock when you purchased it? Curious because I bought a 07 a year ago with 36k. Super clean and bone stock. I don’t race or even drive hard but seeing all of these rebuilds have me so nervous. Should I redo the heads? Or if it’s not broke don’t fix it? Btw sorry about your car man

@@shawnwuanOwned one for a bit over a year, get them done

42 k for a 80 thousand mile car,I am in the process of selling my 09 with 42thousand miles for 38k.

@@7318550239 The market for the c6 is starting to go down, your comment is 10 days old his is 2 months and he probly bought it a few months before his comment, around the peak of the market. Still when I was in the market last year low milage c6z was 40 to 45 no way I would pay 42k for one with 80k

Bless her for helping,, My EX would not have even entered the garage...

..are there any years (C6 Z06)that this wasn't a problem? 😮😮

It was definitely turning some rpm’s when it came apart.

Stupid power steering bracket 🤣
