So i had an issue after putting in a mechanical oil pressure gauge, my pressure was reading low, well i figured out i have air in the line, is there anyway to get it out without disconnecting line with car on? Or is that the only way to do it? [ 2014-09-01, 05:29 PM: Message edited by: 9cobrasvt8 ]

If by chance you have a mechanical gauge in the passenger compartment that works by having a hose connected to the engine and gauge i would not use that in my car. That can cause serious issues if the hose breaks in the engine compartment and sprays hot oil all over the place. use a gauge that is electric and has a sender on the block for safety. just me
But a mechanical gauge does not have to be bled. [ 2014-09-01, 06:39 PM: Message edited by: Tom Renzo ]

Like Tom said, the air does not matter.
How much pressure is low ?

One of them is wrong. Check it with a known good gauge like a Snap On one. They are 2% accurate and i would find out which gauge is correct. Either way your pressures are a bit low which ever gauge is correct.
