Re: 1940 110 Touring Sedan Irregular Oil Pressure

No telling how "loose" the motor is. I run Rotella 15-40 oil in my 327 motor which helped tremendously with blowby. Also a quart of Lucas Oil stabilizer and a long drive really helped to free up the stuck rings on my long slumbering engine.

The oil pump springs can be shimmed to increase spring pressure and increase oil pressure.

On my engine I'd say hot oil pressure at idle after a long run is around 10psi.
