There is oil dribbling from all the other rockers as it should it just that one,and only one is gushing.
There is an internal groove (slot) in the rocker arm bushing. This slot is supposed to be oriented (clocked) so that the groove connects the oil feed hole in the shaft ONLY to the bottom of the rocker & to the pushrod feed hole. It should NOT intersect the top rocker hole.
If the bushing has been incorrectly installed or has turned itself in the rocker arm, the oil feed slot will connect to the hole in the top of the rocker & oil will spurt out. I would carefully inspect the slot in the #4 bushing to see if it intersects the top rocker arm hole.
There have been cases where the top rocker holes have been purposely plugged to compensate for wrong or improperly installed bushings.
It's not too hard to remove the rocker assembly. Loosen the hold down nuts gradually & sequentially so that they all support the spring load as the shaft is released.
As Bob said:
When reassembling, pre-align, make very sure that the oil feed banjo bolt is threaded into the stand far enough to center the feed hole in the rocker shaft BEFORE retightening the hold down bolts. Banjo removed for now. If the stand hole & the rocker shaft hole are the least bit misaligned, the banjo bolt will strip the stand threads before it is all of the way home.
If you decide to remove any pushrods, turn, twist, jiggle them first to break any hydraulic suction. If a cam follower sticks to the end of the push rod, it will be raised out of it's hole & you will need to remove a side cover to get the follower back in it's hole.
Good luck,
