B18 Ticking noise cant figure out what it is

[sennasempre02]

Bought a da integra, engine built when previous owner owned it, having a slight tick at idle and seems to go away with vtec and returns when it's out of it, has forged rods pistons, cams, and supertech valves springs and LMA, I would assume LMA but engine build has around 800 miles on it, runs great and pulls hard no issues just has that tick, previous owner is telling me it's because of the built valvetrain, and someone else has said it is injector tick. Just lookijg for some insight going to link a video
UPDATE check valve lash and everything was in spec, and LMAs seemed okay so still not sure what it is
