[Supras] oil leak path question

[berniek at technicaldevelop.com]

I don't know if it leaks yet, since the engine is not in the car yet.  I 
just posted a question about a 3" diameter O-ring I can't identify, 
since the JDM engine has been apart for 18 months.  It looks too big to 
seal the front main bearing diameter of the crankshaft to the timing 
sprocket.

After installing the sprocket, I used silicone sealer to form a bead at 
the front of the sprocket with more forced into the keyway.  I'll add a 
bit more when installing the crankshaft pulley.  It is also possible 
that the metal to metal seal formed by the pulley bolt flange and the 
pulley is tight enough to prevent oil seepage.  As always, comments 
would be appreciated.
