3 hours this am, no recurrence of grey.
and filter, can't get to the oil
pan bolt to drain it that way but did pump some small additional bit of oil out by turning over engine
by hand. Got out close to the specified amount of oil. I ran it into an old gallon milk bottle and could not see anything but oil
....the engine was under load, running about 2,000 rpm
. So not working it hard.
Temp 140/150, oil pressure starts at 50psi and drops to 42psi after heating
I'll be watching and report back if anything new comes up.
