i've checked pushrods, rocker arms (which have play, all of them). have yet to pull intake. only was noticeable on deceleration especially in 3rd and 4th gear and idle. no ses, oil pressure change, or noticable power loss. any ideas? in regards to the rocker arm play, all have the same amount to, with side to side and up and down movement. more than most the roller rockers i've used.

 

We need info on the car, mods, etc.
