Hi ive just put my newly built engine into my car its a b18c i have just had pit in it:-

CP pistons(9.01)
manley rods
supertech valve springs
arp head bolts
str blockguard

ive connected everything up and when i tick the engine(without plugs) im getting air blowing outwards from the TB side, when i open the TB fuel is blowing out??
when i put plugs in smokee is blowing out of the Throttle body.
The car is only reading 50 50 50 50 all round for compression(probably cause its blowing out of the throttle side) is it the valve springs?
Im really confused note i had supertech valve springs put in too, what could it be??
timing is correct i had a check :(
 
That really sounds like bad valve timing to me. Crank your motor over to top dead center and check that your cam gears are where they should be. Other then that... are you sure your intake valves are seating properly?
