Is there a way to screw this up so hot oil pressure is low (25psi). I just don't see any fluctuation in my pressure reading based on rpm's. 25 at idle...25 at 4500rpm. When cold for the first 15 minutes oil pressure is at 50 and then slowly drops to 25. Stays there whether I'm putting slow or on the fwy. I plan on upgrading to a bigger oil pan, but in the mean time is anything else wrong here? Any help will be appreciated, thanks.

Bill is right to run the oil from the engine to the filter first. Oil coiler is just a heat exchanger and does not have an in and out.
You could be pumping your pan dry at an idle and there is not enough oil returning to it. What are the spec's on your engine. Solid or hydraulic cam? CI heads or Aluminum?
