I recently built my b18 i have 2000 miles on it so far running 8lbs of boost. i have a loud engine drive train, i adjusted the valves to spec as per honda manual. and i pulled the pan off to check the rods. no up down movment but a moderate about of side to side " flywheel to crank pully" movement .019 to be exact. Is this a big deal???? i plan to run 18lbs soon dont want to blow it up. thanks

all work was done correctly as per honda manual. and im a ASE certified mechanic. at a jeep garage, but jeeps, arent hondas lol.
