Engine Mechanical problem
1969 Chevy Truck V8 Two Wheel Drive Manual
i am in the middle of adjusting my valves for the first time since rebuild. The first time I set the no.1 it was at btc instead on tdc and I bent the push rods on no.1. Yeah I know (idiot). Well after I replaced the rods and set the lash I tighten 3\4 turn and the rocker arms are loose. Side to side and I can even lift them off the valve. So i'm thinking I might have crushed a lifter after turn the crank 90 degrees and started to mess with no. 8 but stopped and I turn the crank back to tdc, checked the no.1 with a screw driver and readjusted the no.1 and found I bent the push rods. Now like I said do think I might have crushed a lifter or bent the magnum roller tipped rocker arms?
Its gonna be messy/remove the valve cover that you want do first-
Be spinning the push rod while you tighten it-when the rod cannot turn-STOP, do all the rest for both bank. Now start the engine-the valves will be clattering tighten it down little by little till it stops clattering then turn it 3/4 turn-do all the rest
Or you can follow the firing order put the pistons on compression stroke TDC-adjust like above and start it then readjust the valves
Some V8's 350 such as pontiac, valve adjustment is done by torquing it down to specs-
