I build my v2 shocks exactly exactly like the video saxton posted on YouTube. But no matter what more oil less oil slower bleed faster bleed do it 5 times when I turn the shock upside down I can always feel a pocket of air. Pump it a few times take the top and there will 3-5 large air bubbles. also the shaft sucks back in slightly

This literally driving me crazy. I'm not new to rc but I am to bleeder caps. My race buddy has b44.1 and has the same problem.

I watched saxton video 20 times and I still have air in the shock. I used green slime on the o rings, tried new shock caps, maybe someone can advise or make a point I'm missing
