Wow, what a bummer! The only bright note about going back to
repair your problem is that at least you know where EVERY bolt is,
and even what wrenches to grab...small consolation though.
The only reason I am writing is (besides offering my condolences)
is to say that I have seen such a crank/oil sealing system before, on
my '70 VW camper engine. The front end of the crankshaft is covered
by the fan belt pulley, which goes into the engine block. The only
way the oil is sealed here is by a spiral groove on the outside dia-
meter of the pulley's shaft, and a close fit with the hole in the eng-
ine block where it goes in.
As strange as it sounds, it worked perfectly. From what I under-
stand, this system is on all VW's from DAY 1 'til the water-cooled
boxers and inlines came out.
