I will do another compression check tomorrow morning - per the Toyota King, Prince, Guru, Master Mechanic, Toyota God, and other Royal titles.
There is a mechanical somewhere. It was running fine after adjusting the valve lash. Took it for a ride. Tach'd it up a about 3 times to 5,000 RPM. Parked it. Started it up about 6 hours later.... #1 cylinder was not firing? I believe the failure occurred when I was running through gears, I suspect I did NOT notice any misfire when I drove slowly back into the subdivision where I live. It could not have failed sitting for 6 hours. I suspect valves, valve seats. The rings were bad from the beginning of my rebuild. I don't see how the throttle response was so good if the camshaft was seriously defective.... but... I'm not an engine builder.
I don't have a speedy sleeve.
By the way, I have spoken to the man who supplied engnbldr's cams. I will call him tomorrow and have another chat. He's been doing/gringing cams for over 20 years, he's a really nice guy and sounds like really knows his poop! I plan to put my truck on jack stands for the time being. I will pull the camshaft (engnbldr 261C) and see if the cam grinder/supplier will look at it and mic it and tell me what he thinks.
