[Supras] oil leak path question

[berniek at technicaldevelop.com]

Hi List:

    In putting the JDM engine together, there seems to be a potential 
oil leak path between the crankshaft and timing sprocket.  While the 
press fit between the sprocket and the crank nose may only seep oil at a 
very slow rate, the keyway in the sprocket and in the crankshaft pulley 
appears to provide a nice path for oil to flow out.  The timing cover 
oil seal rides on the hub of the sprocket, so it won't leak oil there.  
Any ideas?

    Thanks.
