Sounds like you are building up to much pressure in your crankcase. I would check the compression and perform a leakdown test to see if you have an excessive amount of blowby.

You can check the compression with compression tester gauge which you can typically rent from Autozone.

Compression Tester Gauge | AutoZone.com

The leak down tester is similar in looks but you will need a air compressor. Instead of me typing it all out here is a link that will explain it.

Leak-down tester - Wikipedia, the free encyclopedia

take it to a shop, get the leak down test done. It should tell you if you have bad rings or so. The dipstick shouldn't shoot out regardless of the o ring. The oil ring is basically there to keep crap from getting in...not to keep it from shooting out the guide.

If you know anything about SRs, you'll know that SRs have blow by. LOTS of it. Even with a PERFECT engine making 500+HP.

Is your crankcase ventilation set up properly?

Leak down is more accurate.

PCV to manifold, and I suggest putting a catch between the two. Nissan PCVs are garage and will let oil in and pool in your manifold.

Then off the T on the driver side, rear goes to the black catch can, and the front goes to your intake pipe.

The PCV is for vacuum, but it closes under boost, that's when the intake pipe takes over and uses that to evacuate the pressure.
