Sounds like you may a valve lash adjuster that wont bleed down, so it may be holding the valve slightly open.have you run the engine? I know that these will tick and sometimes need excessive run time to bleed and adjust themselves properly check the followers to see if any one on that cylinder is tight even at no lift on the cam
