How much preload do I add? I have poly locks too, how tight do i make them? Basically tighten them to finger tight and add preload for these specific rockers right?

 

Thats not all my man. Go to Shoeboxes site. He has a lot of info on this. I did mine the ol fashion way. Had a friend turn the crank until I could adjust each one. I turn mine an extra 1/4 turn. Make sure you make the poly lock snug then turn the nut a 1/4. It'll make sure its tight.

 

On shoeboxs web site for rockers with poly locks (roller rockers) it says :::::"Since the poly lock is not a prevailing torque fastener like the nut used with the stock rocker and ball arrangement, it spins freely on the rocker stud. This gives you an advantage to finding zero lash. With the allen lock backed off, spin down the nut until it just stops. This is very close, if not right on zero lash in most cases. Check your pushrod for proper movement and play with it to get a feeling just how snug or loose the nut should be to obtain zero lash. Once you do that, you can just use the nut to reach zero lash and not have to worry about messing with the troublesome pushrod. This will speed up your valve adjustment.

Another aide is to make a mark on the top of the nut so that you can easily see how far you have turned the nut. I always found it a little difficult to obtain the exact amount of rotation on the nuts under the cowl, because of there being less room to swing a ratchet or other tool handle. I used a little dab of white paint on the top and was easily able to tell when I made a half turn or whatever was needed. I could also just use a wrench to tighten the nuts, then throw the allen key on it and snug the set screw down.

Some like to run the allen set screw down and then tighten it and the nut together. Whichever method works and stays tight for you should be fine. With all the variables in making adjustments to hydraulic lifters like the number of turns for preload, methods of finding zero lash and trying to see what you are doing under the cowl, slight errors are common. Just try to be as consistent as possible and use the method that works best for you. " doesnt say anything about anything else.. Im wondering how much more to tighten them to get the preload and be ok... Im figuring finger tight and then about half a turn and check push rods for play and go from there... Im painting a thin line on the bolts to see how much i have turned each one.. including the ones with valves open so i wont have to turn over the engine...
