Testament of a GREAT Engine...
Testament of a GREAT Engine... The more I work with the Gen III, the more impressed I am with them. Below are some pictures of an LQ4 that I just picked up to rebuild. I got it from a salvage yard and it's got 180K on it. I popped off the heads and here's what I found.
If you're not totally impressed by this, you're crazy. The pictures are bad, but if you look close, you still see the hatching from the factory on the cylinder walls. Unbelievable. If I didn't intend to rebuild it, I could have probably got another 100K out of it.

Yup when we tore the 5.3 out of a buddies truck for his 6.0 build with 212k on it you could still see cross hatch. Then again I'm rebuilding a C12 CAT at work with 1.1mil on it and it still has cross hatching lol.
It's a 6.0L. I've torn down countless engines and I've NEVER seen that little carbon on piston tops in my life. I'm pretty sure it's never had a rebuild - if you saw the outside of it, you'd know what I'm talking about.
I pulled the DS head off and I'm like..."WTF!"
I'm dying to inspect the rod/main/cam bearings to see if they're in similar condition.

I just had a 23k mile LQ4 put into mine... it's an ANIMAL!
Glad to know they last so long, and I've also been curious to see what the dished pistons look like... thanks for the pics!

Nope. No E85. I pulled it from a 2000 Silverado 2500 that had been sandwiched between another truck and a tree. I got it for a song, too. $400 from LKQ in Orlando. The odometer read 181,237 miles (on my receipt) - according to the LKQ guy "Nobody wants high-mileage junk."
Ahem, I beg to differ.

The true test will be when I put the bore gauge to it and see how many thousandths of wear I've got.
I really don't get all hot-and-bothered over looks. Looks really don't mean anything. It's the clearances and taper that make the engine. I just thought it was interesting to see such little carbon after all of those miles.
Anyways, I'll post some bore figures when I get some time this week.
