New rebuild has odd vapors?

Thinking intake manifold gasket........aftermarket performer intake might not sit flush with new gaskets or might need to be re torx.?
So....I did find that the intake needed to be re-torqued. Still have whitish exhaust on driver side.
Cap good, rotor changed.
Vented cap put on drivers side valve cover. No change to exhaust.
Pressure tested radiator at 16 psi. Very small leak on passenger side exhaust bolt. Tightened all bolts. Exhaust seemed the same, but it was cold and dark.
Press. dropped to 15 psi after 15 mins. Held 16 for 10mins?
Will post video tomorrow of exhaust again.
Still need to drain some oil to check for any coolant and also leave cap off to see if any bubbles in radiator.
