The spring brings the valve back up, and there is no play in the rocker. You can see this bank in action here:

℗ unfortunately, you can't see the #1 exhaust valve that well (video shot last week, before I felt the binding). No tapping noise in cylinder 1.

I am now considering that the binding I felt may have only been the spring compressor possible rubbing against a fuel line. (Doh?!)


Regarding injectors:

All injectors are new, with new seals, new seats, and new O-rings.

All spark plugs, plug wires, cap, and rotor are new.

The O2 sensor is new and it has also been strapped to the chassis for a better electrical ground.

Also new are the WUR, the air filter, and the fuel filter.



It has been missing is in cylinder one only. The compression for cylinder one is good. And I am now at a loss to figure out why the plug is sooty, and the cylinder still misfires.
