Lots of good information here- thank you.
I tested the plug wires and two of them were about 1.5k ohms per inch. I will replace the wire set. I have one on order now.
Immediately after all my testing, I did a hot valve lash adjustment and a dynamic compression test for the heck of it- 120-130 psi on all cylinders, there weren’t any bent pushrods, so I am hoping this means it is unlikely that I have a sticking valve.
Went to drive the truck, and my idle drops to near stall when I depress the brake (I have vacuum booster under the floor). Time for a new booster, I think.
I’ll post again when the new wires arrive on Monday.
Oh, and yes, I modified my front bearing cap to be able to remove the timing cover from the outside…..hopefully it won’t come to that!
