have threads left exposed or "slop/play" in the rockers or it can strip out your bolt and you WILL drop a valve - bye bye engine! Buy books on Ford engine building - do not rely on someone on youtube who did not even build the engine to teach you (no offense poster). The reason he can successfully adjust his 1/4 to 1/2 turn to get it to seat on the pedestal base "no slop/paly" is because "someone else" built the engine and installed the PROPER SIZE PUSHRODS to achieve PROPER PRELOAD.
If the pushrod still has play in it, you need a different size pushrod. If the pushrod is tight, you need to properly mark the pushrod, remove it again and measure the distance it was down on the lifter - that is the preload. If it is within factory spec - you are fine, if not - you need a different size pushrod. Again, pedestal systems MUST have the nut tightened 20 foot pounds onto the pedestal - it has to hold/withstand the force of the cam pushing on it - it can NOT...
These are pedestal mount rocker systems - there is NO adjustment to be made. This is nothing like a stud system that uses guideplates where you adjust until the pushrod just stops (zero lash). Zero lash and preload on a pedestal mount system is accomplished with the proper pushrod length. The pushrod length adjusts the preload. You finger tighten the nut until it contacts the shoulder of the rocker fulcrum - then you use a torque wrench to tighten to 20 foot pounds.
great video!!!! really used full!!! a ??? can u adjust the rockers by!! cylinders as in passenger side first ! 1-2-3-4 then driver 5-6-7-8 !! my motor still out!! plus i need to find out whats my push rod lenght gona be know!!!??
im having problems with my 92 mustang and thats what i think i need to do but not sure cause it makes a rattle noise when i step on the gas and has no power. if the valves where lose would that b the problem can u msg me back asap cause i dont know what the problem so can u hlp me u probably get this alot .
@RCSMAXX That sounds like you might need to do an adjustment, its not a difficult really, just time consuming. I'd say go for it and see if it helps. It wont hurt
if my valves where loose would it make a rattle noise when i step on the gas and loss of power cause thats what i think i need to do with my 92 mustang so can u msg me back asap thx
Thats not what everyone on the forums said. I've had no problems on what I did. The reason I back of the set screw 3/16ths of a turn is when I give the adjuster nut a 1/4-1/2 turn its all tight and TQ'ed to spec. This is the way I was taught and told by many. Maybe its recommended on other motors to tighten the set screw after the adj nut. I'm not sure.
I just wasn't understanding the other time but she runs good no abnormal rocker noise. Revs QUICK! I pulled it up to 6200 rpm but the mic on the cam cracked and you couldn't hear it. Its good now how its adjusted.
I'm not sure on the cam. Got shortblock from buddy, couldn't find cam card but its a motorsports cam, b303, e303 or f303 So I don't know. I think iit might be E or F

EOIC method works flawless everytime. Good job man! It'd be better if you had an LS under the hood though :)

may be a dumb question but how can u tell which side is exaust and intake??
representer12 2 years ago
go to 7:19 in the video, there is a picture that answers your question.
You didn't watch the whole thing did you?
Look at the headers, look what valve is in line with the tubes...that'll be the exhaust and the other valve, obviously, will be the intake.
freeloader700 2 years ago
your supposed to do the 1/4 to 1/2 inch turn of preload BEFORE you tighten the set screw.
I will send you a video of the proper way.

It would seem there is no clear cut way.
But im glad you finally got it figured out.
Im going to personally tighten the set screw afterword, so Ill let you know how it goes for me.
