Just to update: been over 1k miles since the head re-torque and the timing cover seal. The small mist under Cyl #1 was indeed just left-over residue. I wiped it off, and ABSOLUTELY NO SIGN OF A LEAK HAS RE-APPEARED. Engine is absolutely 100% dry and clean.

Of course, I didn't have much time to bask in the glory, as the frigid weather brought out a seeping tranny on the front seal and B-2 piston.
But, a quick R&R and new tranny seals all around put a stop to that also.

And of course, again I swore that at my age this is the very last time I'll do a big repair like that - sure!

Old Pearl is tight and dry all over again - time to cruise the Bingo Parlor parking lot and count the thumbs-up!

Cheers,
Old Wrench
