rb25 low compression

[TheRBguy]

I have a series 1 rb25, motor is all stock including the boost. Two drift events ago it blew out the dipstick and shot a lot of oil out, i thought it might have just been the o ring on the stick so i put a new one on it. Then this sunday i took it to another event and it did the same thing. A friend of mine said either f*** rings or pcv valve sticking. It seemed to be loosing a significant amount of power as well. So tonight i did a compression test and the highest compression number i saw was 80psi, the lowest was between 55 and 60, but what is weird is they were all similar? We thought maybe the headgasket but it didnt use any coolant and that also wouldnt explain the blow by. Any ideas on something im overlooking or is it just well on its way to being completely blown up. Any ideas are appreciated thanks.

That's low compression and extremely variable between top and bottom values. How does this engine even run?

Take it apart and be prepared to rebuild it.
