Once I got everything apart per the fantastic videos, I found that Cylinder 7, which was giving the crazy dashboard errors in the AFM video and running rough since #7 had continuous misfires has an intake vale that never fully closes. I tried to capture in pics that it is always slightly compressed. Much lower than cylinder 1 which is also and afm cylinder.
I pulled the spark plug, shined a light and then used my phone to cover and look down the intake chamber and sure enough I could see crescent-shaped light appear as I moved my flashlight around (with no rocker arm attached per the pics)
Is this also a common problem?
Suggestions on what to do next? (By the way, I live in Austin Area if there are any shops you'd recommend)
I'm assuming I need to pull the head and have the valve replaced along with valve guide, etc. Or am I mis-diagnosing something?
Thank you for all your assistance so far.
By the way, I did by the kit, could bounce the rod a bit, but I suspect it meant nothing since my rod seems to rise as high as the other rods.
