Remove valve covers, remove stock rocker arms... install new studs with
locktite (red). Loosely install new rockers on studs (install guide
plates and pushrods if applicable). Remove all plugs. Rotate engine
via alt pulley to TDC cyl #1 (marked on harmonic balancer). Tighten
rocker on cyl #1 until pushrods have zero lash (no up/down, but with
finger friction if you twist the pushrod). Lock down rocker (do both
intake/exhaust), rotate engine 90 degrees (there's another small mark),
go to next cyl in firing order, adjust rockers/lock down, rotate engine
another 90 degrees (another small mark)...adjust next cyl in firing
order.. etc.. continue for all 6 cyl. You'll need to dimple your
stock vavle covers to clear studs, hammer and punch can do it.
Install covers.. Turn over engine to pump up rockers.. listen for
tappets... wait... do it again.. continue 4-5 times, for about 5 seconds
each... Noise should go away... Remove covers, check rockers for
binding, loosening... If anything is loose, start over from beginning
(sucks, but is the best way). If everything looks good, reinstall
plugs... Fire it up... if tappet occurs, run not more than 10
seconds... wait 5 minutes, re start... Noise should be very light...
IF REAL LOUD, STOP!! CHECK EVERYTHING AGAIN.
A small amount of tappet sound is 'ok'... drive under 3000 rpm for first
50 miles... Enjoy!
Sam
