Hello
My engine was rebuild around 9,000 miles ago. Recently hear the thicking on the push rods so I'm trying to recalibrate them.
I did the procedure of loosing the nut until make the noise, then tighten until the thick is gone and turned it 3/4, everything looks and sound correctly but when I drive my truck and push the throttel a little deeper, there are bangs coming from the TBI, so I guess the intake valves are not closing enough when the compression is working and that is caused because the rocker arms nuts are loose.
So what you think, I've done some research and some guys recomend only 1/8 of preload and others even a 1 complet turn.
The engine is a 350 TBI with flat pistons and a Lunati 10120101.
Should I loose or thight the rocker arms nuts?
Thanks
