If I tightned them to much you'd know right away and back adjustments off a quarter turn. I still do this and was wondering if any one else still practices this. Beside being messy with the oil spraying the engine, I never had any problems doing it this way, but again I'm talking about older engines with hydraulic cams.
I gave it up - too messy, too hot, not necessary. I bring a cylinder to TDC, adjust I and E, rotate it 90 degrees and do the next one. Cinch it up until zero lash, then a quarter to a half turn.
