Importance of PCV and what happens without it.

Yeah I still see some condensation with the pvc on mine now but not as much as before and never as bad as the goo in that pic , mine has always been wet like it doesn't mix with the synthetic oil to form that goo you see here , I'll withhold comment regarding what may or may not have been done by the person that installed the motor and tuned it originally before it was brought back to you to deal with .
