oil pressure help

[mannyssj13]

Just did my oil pan gasket the other day and ever since then my oil pressure seems to be a little off not really sure on the normal pressure and where it should be. In the picture where the two red lines are the pressure is there when i first start the car as its warming up/ driving normal then after a couple miles or maybe 10 mins it drops down to where it is now and move normal as I drive. Not really sure if that's good or bad and also would my oil return line have anything to do with oil pressure?

maybe oil pressure sensor... or your pump is going....

On cold starts, the oil pressure will be higher, as the oil is thicker. As it warms up, it thins out and pressure decreases.

That being said, it'd be helpful to see how much it actually changes. Do you have access to a oil pressure gauge with numbers that you could quickly hook up?

Does it do this when you start the car with the engine already warmed up? Why do you ask about your return line?

Not really sure if it does after warm start ups last couple times I drove my car it was only to a friends house and ended up staying awhile so my car wasn't warm but ill look out for that and see. Reason i asked about the oil return line is cause i have a rubber line and it has a little bends on the holes and thought maybe that would cause it and don't have oil pressure gauge with numbers.
