Opinion On Adjusting Rockers Cold Or Hot

[Dandeluxe]

WENT FOR A 300 MILE CRUISE A COUPLE OF WEEKS AGO AND MY TRUCK STARTED MISSING. SO WHEN I GOT IT HOME I NOTICED A STRANGE NOISE UNDER THE VALVE COVER NO. 4 CYLINDER HAD A BENT PUSHROD AND THE ROCKER HAD SLID OFF THE SPRING. I CANT REMEMBER HOW I USED TO DO IT?WHEN I PUT MY NEW PUSHROD IN WHAT IS BEST? SET THE NEW PUSHROD COLD OR HOT AND RUNNING. NOTE IT IS A 350 SMALLBLOCK. IM TOLD COLD. TO BUMP IT AROUND UNTIL THE 2 VALVES ARE CLOSED AND THEN SNUG DOWN THE ROCKER AND FEEL THE PUSHROD WITH MY TWO FINGERS AND LET IT SPIN SLIGHTLY THEN 1 FULL TURN WITH THE RATCHET. HOW WOULD YOU DO IT. I KNOW RUNNING AND HOT IS A BIG MESS. THANKS, DAN
