Default Oil dipstick pops out while driving

So the last few times I popped my hood to check the oil level, my dipstick is popped up against the hood like something is trying to push it out. If the car is just idleing it dont pop up but seems to be after I been driving for a while or get a heave foot, why is this happening?

I would also suspect the PCV system. Did you modify it or have you checked to make sure it is not plugged ?

PCV system or Too much piston blowby. Could be an indication of broken ringlands/piston.

Clogged PCV system or worn out piston rings.

with the engine running, pop th pcv tube end off of the valve cover and see if you can feel some vacuum. Try at both idle and at 1500-2000 rpm's

Next try taking the oil filler cap off and put your hand over the opening to seal it.. see if you feel vacuum or pressure at both idle and with some throttle.

Ok so I changed out the PCV valve today, still doin it. No suction that I can feel or pressure out of the oil fill cap. Tried a test at idle, and throughout the RPM range all the way to like 5K. Took it for a ride for like 20 min, pulled over and the dipstick was still down. Did a WOT pass shifting at 6500-6800 rpm, pulled over checked again and it was popped up a bit again maybe an inch, still no vaccume or pressure outta the cap or the dipstick tube.
What else can I do to figure this out? Its not bloeing any smoke out of the exhaust or anything
