[DeTomaso] ZF Drip

[John Taphorn]

Mike

After the ZF is drained, remove the offending bolts and clean the bolts and 
holes with brake cleaner.  Then coat the bolt threads with YamaBond 4 ( 
available at your Yamaha dealer) and retorque.  This is your best chance at 
sealing the leak.

As an FYI, Quella does not use the gasket in question and only uses YamaBond 
in that application.  I have followed that advice on many rebuilds and no 
leaks at the bottom plate todate.

Good Luck
