[DML] Re: Timing Gear Cover Leaking...Backfiring?

["content22207" <brobertson@xxxxxxxxxxxx>]

PRV has a nifty way of locating TDC cylinder 1:

Are 2 plugs on top of the engine. One farthest from the "front"
(closest to the flywheel) is used to locate #1 TDC. Rotate the engine
to within 20 degrees of TDC via the timing scale. Remove that plug and
insert a foot long 5/16" (8mm) drill bit through the hole. Bit will
rest on #3 or #6 counterweight -- can't remember which -- into which
an 8mm indexing hole was drilled at Douvrin. Rotate the the engine
until the bit drops into the indexing hole. Engine is now at absolute
TDC #1. Be sure to adjust your timing scale accordingly.

This is a factory procedure BTW.
