Recent problem with start up pressure. Gauge will not read any pressure for a few seconds then slowly pick up to around 40 lbs. then shift from 30-40 until motor is warm.. Once the motor is warm there is no issue with pressure. Idle at 40 and rise to 60 when accelerating . ???

 

Are you sure you don't have anything slightly blocking any of your oil ports? I had oiling issues and ended up finding a small ball of RTV pushed up against the barbell in the back of the motor.

 

I'll check but it's something that recently started. At the same time it started getting colder and the speedo also stopped working all together

 

Ok in that case start by checking the grounds on the back of the drivers side head.
