Yesterday I spent some time tearing down the engine. I methodically bagged and tagged the hardware as I went (just in case, ya know) until I finally got to the first money shot of sorts.
Sorry; I didn't realize that photo was a bit blurry until I uploaded it off my phone. Whatever. I sure do love the size of those intake ports. They definitely dwarf the ports on my old Chrysler 2.2 cylinder heads. :laugh:
Yesterday's goal was to remove the heads, so of course that was accomplished soon after the above photo was taken. (Good grief, those things are
heavy!) Once they were off, I casually glanced at each piston top just to see how things looked. Seven of the pistons were identical to each other, meaning there was nothing out of the ordinary and they looked exactly as expected. But then there was cylinder #2.
One of these things is not like the others...
Hmm, that's an unusually-well-defined spot of shine. If you aren't familiar with OEM Vortec 454 heads, that is the shape of the combustion chamber. So in other words, it appears this cylinder's rod bearing was compromised such that the piston was contacting the cylinder head. It's a good thing I had already decided to rebuild the bottom end.
Anyway, the heads were then dropped off at C&T for cleaning and inspection, as planned.
