OK, so I found TDC
and I am adjusting valves.
The method I am using is ,,,
At TDC, adjusting E-1, 3, 4, 8 & I-1, 2, 5, 7.
Then one turn to mark and adjusting E-2, 5, 6, 7 & I-3, 4, 6, 8.
I inspected all the rocker arms, balls, and nuts. I also ran all the pushrods around on a nice piece of glass to check for bends. All straight.
BUT there is weird problem on #7 Exhaust!!!!!!!!!!!!
When I check for ZERO backlash on #7 Exhaust, I can push the pushrod down about 0.140 before it stops. It has enough spring pressure to push me back up.
This feels like the spring inside of a lifter allowing me to fully seat the pushrod and then its strong enough to push the pushrod back up.
In other words, I could have zero backlash at one area, but then push the pushrod down 0.140 and obtain a zero backlash at that setting.
I can push my pushrod down, pretty easy, about .140 and it springs back up.
IS THIS NORMAL? I didn't have that happen on any other valve, just exhaust #7.
Another thing, it started to have a distinct PING or KNOCK on one cylinder. That's why I started with the valve adjustment first. Do I need to remove intake and start going thru the engine. It was a great running engine until last week. We started it and it started missing. Thanks yall.
