Rick,
The grey stuff may be STP additive. STP leaves a grey slime over internal parts,
especialy in nooks and cranys. I don't know if the stuff does any good, but it
sure leaves a mess behind.
I'd have the crank polished and rods checked for straightness. Good opportunity
to have crank and attached parts balanced as an assymbley.
Good Luck,
Jim Davis
