Inserted a drill bit after removing the bolt in the centre of pump,s head , the place where u inset the dial gauge.
Then rotated the engine by hand using a long bar n socket on the crank pulley bolt. Observed the in out motion of the drill bit while holding it there, a two man job. Got the Tdc as per rave, ( first set of cam lobes) n got the max outward movement on the drill bit. That's how i got the max cam lift.
BTW, got a new issue now. My new battery is dead n after starting thd car jumpers from another truck, found the alternator provides only 12.8v at 2000RPM, no load. But I stil don't get the charge light to indicate which functions as it should. Now to find an alternator. Anyone have a matching part no from Denso? Densos are plenty here with jap used parts.
Could this alt problem create the observed data above, specialy the modulation data?

Maybe just the regulator and brushes, worth a try rather than an alternator.
