Intake valve fail, causes a miss at near all RPMs. Black shit coating the intake valve. I'm guessing it died or it's out of spec.

Check the clearances BEFORE you pull the head. Calculate what shims you need with the head mounted...If you check with teh head loose I dunno if it will change as the head is torqued..but it may. And it's just good practice. Shopes that set them (heads) up professionally will use torque plates.Model192 wrote:no idea yet, i broke the plug off in on that cylinder too, so out it all comes
