You could. There are plenty of people that would just add some Bars Leaks or
that Surbaru stuff and keep going for a few more months to years. Me, I
have the kind of luck where the heads would blow in P-Town, MA on a late
Sunday afternoon in 98 degree heat. A thunderstorm would roll in shortly
thereafter while waiting for AAA.
Actually, my heads are doing the exact same thing right now so I'm looking
at a rebuild at the moment.

So, does this mean I should ignore the leaks? I'm not accustomed to
ignoring failures on a vehicle, but if this is truly "normal," then I can
sure use the money elsewhere. But maybe this is just one more reason for me
to rethink whether the van is worth more to me than the money I could get
from one of the vanagon nuts around (there seem to be a good number of
them).
Thanks, David McNeely
