i dont know how that cylinder got messed up like that like if something was in there
:(

wtf!! when did this happen?

Damn!!!

Damn man. I hate to see that!
With the way you do things, Im stoked to see what your going to do next. lol
408?

Your ring gap was too tight and locked in the cylinder on a downwards cycle and ripped the ring land off. Time for forged pistons and and properly gapped rings.

That sux lol.
You know what time it is!!!
Put a new piston in and run it while you build something.

Man that sucks now the million dollar question everyone wants to know is.... what are you gonna build next?

happened yesterday....it was bound to happen this was just a pull out motor ly6 off a 09 2500hd.............whats a good forged rotating assembly ?i was thinking on just replacing piston and head but nah im just going to pull it ..i dont know im thinking 427

427 and twins ftw! Lol

I know ;)

427s are weak. :)

I told you here and in youtube.....that sound was more than a lifter.

Sorry to see ur engine like that.

Hope you can build something soon and be back to the road in no time.

408ci ftw bro...most reliable strocker on the road !

I thought those Titanium retainers were supposed to be bulletproof, I just bought my cam swap stuff and the guy tried and tried to sell me those upgraded titanium retainers but I decided not to. Can't wait to see what you switch to, good luck with the repairs!

thats badass zack, oh well just was just a baby six0 they are a dime a dozen.

Offset rockers FTL.

That sucks... time to build it stronger. Alot of stock ring gaps are .011 to .013 on the top ring. Doesn't take much heat to make it touch

I did the same thing with my 5.3.. Broke a spring and titanium retainer

the carnage continues as i remove passengers side head...

i dont think there was this ring gap fail etc...it was the prong from the spark plug that broke off and mest up everything.check it out.
now what would cause that plug prong to break?too much heat?wrong gap?
im going to fix myself but need to prevent this from happening again.

Carnage from the other broken hole got transferred to that side of the motor through the intake. Had nothing to do with the electrode on the spark plug.. That hole was a innocent bistandard.

damm u think so...another thing that sucks i just inspected the turbo and the exhaust side some blades are roughed up on the edges..damm f/i world is putting me to the test.

Can you take pics of the other three pistons on that side of the motor. I take it you never did any WOT pulls with fresh plugs to check and see how even intake distribution was by reading the plugs? The tops of the pistons will show if any holes are burning rich/leaner than the others.

From the pic above it looks like #2 is burning way hotter than #4 since alot of the carbon is being burned off the piston. I'm really curious how distribution is on this holley intake.

no i didnt do a plug test like that i dont know if Allen and Ray did not sure but heres a pic

if it means anything the plug that goes to that very back cylinder went completely closed one time on me

ya sux when you get something together and then it craps out on you that fast. I went from the 4.8 to the 5.3 then the 5.3 only lasted like 3wks if that.

Damn the bad luck man. But at least you don't give up, keep improving and making it better.

Zach did you clean the #2 piston at all? 4,6,8 all look pretty close to each other. How about a pic from the other side?

no i didnt wipe em down, i just let towels soak up the coolant out the cylinders.
