Anyone know what would cause my oil pressure to drop?
Normally runs from 40 to 50, but lately(2 weeks) at Idle it has been dropping to about 20. I do have a small oil leak in the lines for my remote oil filter but have had this for a while.

Thanks.

Well the OEM guages aren't...

the most accurate ones. 20 psi is fine at idle and it should go back up as soon as you accelerate and put the engine under load.
If you oil pressure drops too far the sensor will cut off fuel supply to avoid engine failure.
