Yes, its appears good, no gas smell or no increase in volume, so I dont think it flooded the crankcase. Speaking of oil, what should be the normal oil pressure for one of these engines in good shape?

That is going to depend on how the engine was setup clearance wise and where the by-pass is set. On a new engine with tight tolerances maybe around 60# or even 80#. On an older engine it can be a lot less, say 10# to 20# near idle, sometimes lower.

Rumbleseat quote:

OIL PRESSURE: Oil pressure spec for early ‘48 and older engines is 30 psi @
30 mph. For late ‘48 and newer engines it was increased to 57 psi. at 40 mph.
Current performance flathead professional engine builders recommend pressure in
the 80 psi range for hopped up street engines.


I believe some say 10# per 10 mph?
