just recently did hci on my 89 gt and the rockers seem to be makin a lil more noise then normal, so i was gonna re adjust em just to make sure everything is all good. ive seen many how tos on stangnet but many of em are so diff. so i was wondering which way was the best for me to do? when i originally did them on installation i made sure that the valve was closed and did the turn nut until pushrod has risistance procedure, and then locked em dwn with allen head, all rockers seemed kinda loose but when i primed the oil pump everything tightened right up to where it seemed good, still had some preload in it. is this wrong , i didnt follow the firing order or anything, why is the firing order important in this procedure? car ran fine so it couldnt of been to wrong lol. hopefully u guys can point me in the rite direction. they r 1.6 ford racing roller rockers stud mount on tftw heads. thanks for the hel[p guys!

you did it right but missed a very important step. If you indeed did turn the pushrods until slight resistance, then locked the locking alle screw, you messed up. Your supposed to turn the pushrod until slight resistance with fingers, then MAKE 1/2 TURN more with wrench, and THEN lock the lock nut. As u stated u missed the most important procedure. Thats why they are all loose dude.

I agree with ShortThrow. That's exactly how I did mine, you do need that extra 1/2 turn with the wrench, then lock it down.

you have to do the half turn past, but another step that i like to do is to pre-prime the lifter by squirting some oil in the hole before i put is in the valley

I was always told to just do half a turn than if they are noisy then you can always go back and remove valve covers and give them another little crank each. U never want to over tighten. Its always better to walk forward

you follow the firing order so you can adjust the vavles in order and get the lifter on the base of the cam(following firing order just makes it faster to do)if you don't follow firing order you just have to do a little more work by turning motor over more
