rocker arm adjustment
rocker arm adjustment i have a lt4 conversion in my car its got the 1.6 roller rockers. does anyone know what i should adjust my rockers to cause i think one is to tight causing a pop through the intake so im gona re adjust them
ss imposter perhaps thats your method but as far as i know thats incorrect. Once you hit zero lash, whish basically means having no up/down play on your push rods, you want to make no more than 3, 1/4 turns, or a full 3/4 turn. Its important to get the 3/4 turn but do not exceed it. After this, check your pushrods and make sure there is no up/down play. If there is start over. Also, its important to note that if you can move them a little bit left and right, thats ok. If your doing the lt4 conversion and have the self aligning rockers than you should be ok with what i just explained.
also, If you want to set the lash by bringing each cylinder to TDC, watch the valves and the pointer on the balancer and follow the Firing order:
1-8-4-3
6-5-7-2
Adjust both intake and exhaust of the cylinder that is at TDC. You will have to make 2 revolutions of the crank, stopping at 1/4 (90º) turn intervals for each cylinder.

I also set the lash when the lifter is riding on the 'base circle' of the cam and not on the ramp itself.
