Alright, so i have a 91 ef with a b18a1, not sure of the mileage but, i want to know what is making it smoke in smokes when i let of the throttle and get back on it, and then when i put it all the way to the floor is makes a ticking sound and blows black smoke like a diesel lol. i figured it could be a valve and rings, not to sure though i plan on building another b18a1 but i want it to be strong i have a medium range budget and i want it to be able to withstand boosst if i decide to turbo it.......
