So whenever I start my car it’s fine till a little then the oil starts leaking when it’s at full temp. Looks like a oil pan gasket maybe I just replaced it and I’m getting frustrated. In the pictures it doesnt look that oily but it is. Anyone else had this problem?

Check the back of the intake up top... below where the pcv valve is. It'll be very hard to see back there without a scope or a bright light and mirror. The lower intake gasket may be leaking. Does it leak idling... or do you have to drive it for it to leak ?

Have you replaced the screen before the pcv valve ? That screen could be clogged causing pressure to build up in the crankcase.

I have not replaced the screen and it drips a small amount when idling and leaves a nice little trail on the street

That blue neoprene felpro oil pan gasket is the bees knees. I use them on all of my engines. I assume you did dab the corners of the gasket with silicone by the crank ends.

Usually, the rear main seal will only leak while driving. If the pcv is clogged it can cause all types of leaks. The lower intake valley strips have gotten me a few times. They don't tend to leak a trail of oil though.

You may want to run some dye in the oil to pinpoint the leak, a dye kit can be picked up pretty cheap.

Yeah I’m not super sure I just pulled the motor and don’t want to do it again for an oil pan gasket that’s brand new
