Back at it again. Not optimistic about the condition of the 6.0 with the piston grenading so as a back up I bought a complete running 5.3 for $400 bones. I can sell the accessories and make that back. Not planning anything crazy, maybe. mild cam. Also thinking about sealing the Fitech and either using the stock intake or switching to a Holley Sniper carb for the old school look.

Started tearing it down & it looks pretty decent, cleaned up the carbon build up from the pistons but the cylinders look good. I’ll scavenge the cam from the 6.0.

Good buy on the 5.3.

interested to see how the parts look when the bottom end is apart, see how bad the piston skirts look etc.

Started tearing into the 6.0. The plot thickens! Don’t know what this cylinder is going to look like but sure it won’t be good.🥺

I guess they saved a few bucks on new valve springs, huh?

It gets worse the further I tear into it. The head is destroyed, deep gouges I the cylinder wall. $$$ down the drain.😡😡🤬

No. It is/was a new build still wrapped on the pallet, but since I wasn’t the original buyer, the warranty was non transferable. I’ll try to get a better pic of the cylinder. In the meantime, here’s the rest os the mess left in the tray.

At least, t was able to salvage th cam, lifters & pushrods. I was hesitant about the oil pump but the screen on the pickup tube kept fragments from getting into it so I reused that as well.

if it were me I would disassemble the oil pump and check for small metallic debris, clean it all up, imcluding the bypass, lube and assemble. cheap insurance.

Do you know the cause of the destruction? Is wasn't just a broken spring was it???

dsraven 10-18-2024 09:39 PM

Re: '50 3600 re-do. Shortening things up!
 
looks like a valve spring broke, then the valve dropped out, then the piston hit the valve, then the pocket book was hit hard.

Wow. Thats something tp think about!

That’s what I suspect, especially that last part!

After several months of lack of interest I decided it was time to bring the thunder! It runs!

I think I’ve narrowed down the cause of my 6.0 failure. I’m thinking there’s a stuck injector that cause it to vapor lock. I noticed the strong odor of fuel & a hint of black smoke coming from the 5.3 & from what I’m hearing, it’s a common problem with FiTech injectors. Thoughts?

The only real way to know is pull them and have them tested
