thanks Loren
I think it's do-able - pan is clear to remove, I have most of my tools 
with me
have a drill (but not my hone, sadly)(I actually do own one)

the pistons actually move in the bores
I can wiggle them about 1mm (maybe not that much, but noticeably and 
visibly, side to side, around and around - there's definitely movement, 
but not much if any ridge, so I thought I could get em out easy enough 
- thought it'd be nice to tighten up the bottom to meet the 
tightened-up head on top)
that's why I was thinking do 'em

any ideas on how to improvise a hone, a groove cleaner? no auto parts 

it's definitely goo, not just oil
highly emulsified with air, but dense, almost like a foam rubber

could this still be a grommet?
or is it definitely blow-by?

oil I'm using is 15-40w petro
(but I am intending to switch over to high-oleic Canola, which 
apparently has better lubricity and almost as good durability
since I'm running on veggie already, I can filter it into the fuel tank 
when I'm done!)
(now THAT would be the wrong oil)(but I'm 2/3rds all-veggie already - 
B100 in the diesel tank, WVO in the veggie tank - looking forward to 
veggie in the sump as well)

thanks for all the tips!
