Re: 443 high oil pressure - cause for concern?

Our 526 SIX had the same problem....pegging at 50. We solved it by removing the plate under the oil pump, the screen pops out with a little coaxing.
We removed the spring and ball, cleaned the ball, cleaned the seat and reassembled.
Be careful to note the depth of the adjustment screw when you take it apart.
