I think it's do-able - pan is clear to remove, I have most of my tools
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!
