dfhn you have to get the piston to TDC you do this by removing the spark plugs and sticking a small screwdriver in the spark plug hole then turn the engine manualy you will feel it come to the top then on that cylender you thighten those 2 rocker arms hand tight then once their hand thight you go 1/2 turn with a rachet the guy that told me this owns a machine shop and has been building engines for over 20 years
50 lb/ft lubricated with oil. Check out the link I posted.
http://torquespecs.xoompages.com/gmfs70-88chv8.htm the rocker studs are 7/16-14, same as the head bolts. should be torqued to about 65 ft.lbs.
on a '95 300 straight 6 with rocker arm bolts, not studs with nuts, the torque spec is between 17 and 23 foot lbs. if it has studs with nuts it is older and the specs are different so you will need to research that more.
There is no torque sequence just torque rocker arm studs to the proper torque
No you can get screw in studs mainly for high performance engines.
They are pressed in.
Your best bet is to buy the manual. There are multiple ways of adjusting rockers and it depends on the vehicle. Your loose rocker arm may also be an indication of a bent push rod, bent valve, or worn out cam. there are 2 types of rocker arm studs pressed in and threaded in. if it is pressed i suggest buying the same size threaded stud, tapping the hole and using 2 stacked nuts screw it into the hole in the head. if its threaded just remove the old one and thread in the new one, be sure to check torque value for this application answer if a rocker arm is broken, u need to remove rocker cover the rocker arms are all on one tube bolted to the head remove the nuts that secure this tube slide as many rocker arms as need to get to broken rocker arm, off the tube replace with new rocker arm replace others that u needed to remove. sit tube with rocker arms back in place making sure that u align all rocker arms to the proper place tighten securing nuts to proper torque over tightening will break the studs then adjust rockers to specs if engine has hydraulic lifters you will not have to adjust replace rocker covers using new gaskets if the rocker ram is loose, adjust to specs if engine has hydraulic ligters, torque to specs job is done
Some do some do not. Look at the stud, if it has a nut built into the stud bottom, then it is a screw-in
With the valve fully closed and the lifter fully at the down position, tighten the adjusting nut until there is no up and down travel in the push rod. Then tighten the adjusting nut 1/4 turn. This is only if you have hydraulic lifters. Tighten the rocker studs to 50 ft/lb of torque. These are the bolts holding the rocker assembly in place.
