So discovered a couple issues. #5 rod cap bearing after plastigaged showed a chunk of something. I thought it was clean enuf obviously not. I tried getting it outta the bearing shell, no luck. Rod journal has a very slight nick/mark. I can feel it with fingernail run backwards across it. It doesn't "catch" my nail though. I wiped everything before assembly..dunno how I missed it dammit.
Issue #2 side to side clearance on pistons 7 and 8 is 0.0016"
Spec is 0.006" to 0.014"
Pics attached. Mark on journal is beside pencil in pic.
0.0016" feeler gauge in pic too.
Oh new bearing on order. $12 not too bad.
Should I be concerned of the journal "mark"? A light 1000 scuff? Crank has been polished.
On a good note all rods plastigaged within spec.
#1 0.0018
#2 0.0016
#3 0.0013
#4 0.0016
#5 0.0019(being replaced)
#6 0.0020
#7 0.0016
#8 0.0015
Thanks!
