There seems to be some debate about the position of the cam lobe when taking the measurement, whether better pointed directly away from the valve shim, or with the engine at TDC (not shown), as per the factory service manual. I think the position shown here makes more sense as that's where the clearance is at its maximum.
What cams are you running there, are they after market. The duration and lift look a bit wilder than my xjr 1300. I am thinking of fitting a pair of fj1100 cams
You mention rotating the engine counter-clockwise but from the camera's angle you are rotating it clockwise. So which reference point of view should be used to determine CW vs. CCW? Thanks. And why shouldn't you use an open end wrench on the intake cam? Just curious.
I’m really puzzled. Why isn’t piston bending those intake valves as you’re rotating crank? Because the tool is holding the valve open how is it possible to turn crank and not cause binding?
Would only change a shim when the play is not enough. If it is a little wider doesn`t matter... He said he would change from a 278 to a 280, that is a difference of 0,02 mm, a human hair is 0,07 mm .
