Removing rod caps would have voided the 90-day warrantee as well.

I'm very confident in this one. I've been through it completely. I even borescoped it ahead of time before teardown. It cranks around easily, has great compression using just the impact wrench, and I found no major problems.

Those cylinders look amazing! These series 1 bottom ends are so tough, you can probably put some serious power on top of that block without touching anything. That engine was a good find.

Ya, I know they cost a bunch but....
What about the rod and crank bearings? Are you going to plasti-gage them to check tolerances?

Cylinder pressure is one thing.......oil pressure is another.
Don't the Series 1 have forged pistons?

I think that the L67 Series I Pistons are hardened/Coated not forged... The Rods may be another story tho

Thats Pretty typical of a 3800 V6.. More than most of the time even with 200k the Bores won't be beat up... If we didn't have so many issues with the L36 Upper intake these engines would be lasting a lot longer..

Just Look at SonomaZR2... 300K+ Miles and still going strong

(other box is in the trunk)

I didn't feel like driving home first to get the green car, then a mile farther to get my trailer, then reversing the whole process after unloading.
