I recently bought an 85 Westy with 150K orig miles.  The engine runs very
strong but it has started to leak antifreeze on the driveway from one head.
I am very reluctant to add stop-leak additives.

Unfortunately, I don't know the history on the van because I bought it from a
clue-less used car dealer.   How long should I drive the van before I get the
heads done, rebuild, or replace this engine?

Thanks for any help.
