sup h-t

i just finished building a fully build b16a idk if i did something wrong but the motor cranks and it runs but after a while the motor has been running it starts leaking oil thru the head gasket little by little idk if i tight the bolts to much that i squeezed the gasket to much but it blowings white smoke thru the exhaust like if the gasket was blown all the seals are new so its not a cam seal or vtec seal a little help would be nice.....

here are a couple of mods the motor has done

block

balanced crank
type r oil pump
eagle rods
wiseco high compression pistons 12:5:1
sleeved

head
port and polished
omni valves
omni retainers
omni spring set
arp head stuts
cosmetic high compression head gasket
three angle valve job
buddy club cam gears
buddy club cam stage3
blox manifold
rc 310 cc
golden eagle fuel rail


and more i cant remember

but i would like your guys opinion before i tare the motor apart
here are a couple of pics of the swap i need this thing running
