I recently installed an Edelbrock Performer Intake Manifold but this problem was happening before this but not as frequent. The two could be completely unrelated. When I start up the car my oil pressure guage doesn't work at all it just sits there. After driving sometimes it will kick on or after I stop and turn it back on. I think it's just a bad connection in the dash but I want to make sure it's not hurting my motor. I see no signs of oil leaks anywhere and just did an oil change after I put the intake on. No other guages are acting up like temperature so I'm pretty sure it's the connection but I just need clarification. Thanks.
