Proud of what I do…. Thank you sir!

Joey,

I took my 2013 Yukon out for a drive this morning wow what an amazing change in the drivability of that vehicle.

Unbelievable … The shift points are amazing, smoother than ever before… and NO active fuel management crap…

if you were here I would kiss you on the lips man.

Thank you so much.

I think the bearings were toast! That is the metal shavings in the bottom of the pan.…. Surprisingly it didn’t damage the crank journal or rod. All specs are good! On to the next part!

Bad day for this bottom end! Rod bearing 4 was trashed. Surprisingly it didn’t damage the crank only some minor pitting was able to polish it out. Waiting on parts to get this thing back together. 2 of the head studs were also loose and not tightened.
