What causes your oil pressure to run high?
If the oil is too viscous or not viscous enough, it might be the wrong oil for your engine. The temperature of the engine also has an effect on oil pressure. Since oil becomes thinner when it heats up, and thicker as it cools down, the oil pressure in the engine may be higher than normal during start-up.
What should the oil pressure be on a Harley Davidson?
The psi is about 28 at that speed after about 30 min on the road. The manual says that the pressure is supposed to be 32 psi with oil temp @ 230 deg. f. @2000 rpm (55 mph). I don’t know what the temp. of the oil is, but there is a time when the pressures will meet those specifications, which is about 20 min. on the road starting from cold.
What should oil pressure be at 70 mph?
70 mph is cruising speed on most roads in Texas. The psi is about 28 at that speed after about 30 min on the road. The manual says that the pressure is supposed to be 32 psi with oil temp @ 230 deg. f. @2000 rpm (55 mph).
What to do when oil pressure drops on a dolt?
Dolt has you covered above. As suggested, polish the plunger and clean the bore so that it (the plunger) slides easily in the port with no binding. While you are in there, pull the plate and check out the pump. Make sure to use new orings when reassembling and ensure the pump is aligned.

Why does my oil pressure drop when I cruise?
A partial blockage in the feed line to the cam case could also cause the erratic oil pressure but two sources listed above are the usual suspects. Oil pressure should read 40-50psi on start up but drop to 8-12 when warmed up and rise to about 32-34psi at cruise and stay there.
