We prefer another method, explained in this sticky:
https://www.d24t.com/showthread.php?t=1684

Rather rotate the loosened rear camshaft pulley relative to the camshaft and tdc. First rotate the IP outward, not to set timing but to make future rearmost glowplug and/or injector access easier. As Redarrow suggested, loosen slightly the injector hardlines at the IP so they don't get strained when rotating the IP. Retighten them (spec is 25 Nm, 18 ft-lbs, not as tight as most think!) after locking down the IP in its new position.

Then you will set the timing by slightly rotating the (loosened) rear camshaft pulley until your desired reading (.95mm?) shows on the dial, then lock down the pulley bolt while holding the pulley in position, somewhat tricky, may take several attempts.

You will want:

Dial indicator

Dial indicator extension piece

Cam pulley wrench

Dogleg cam pulley bolt wrench (tight access at firewall in a 240)

Injector hardline wrench is nice to have-- some of those nuts are a challenge

NOTE: IP pulley lock pin is not needed.

Usually fuel wants to drip out of there, no worries unless you blow some dirt in or introduce dirt on the end of the dial indicator plunger piece.

Flared end may have gotten deformed from previous over tightening. See warning above. Happily, you can order new replacement from brickwerx.com.

That arrow is more like a wide triangle, not likely like it could bend along the direction of flywheel rotation. Is it bent in toward the flywheel?

We seem to like .95mm, why don't you start there and see how that works?
