Hi to those mechanically inclined,

My brother has a 1986 Ford Bronco II (V-6) with a quarter million miles
on it.  He reports to me that he has some water in the oil (nope - don't
know how much).  He asked me if I thought this could be a head gasket.
My first thought is that it could, but after cogitating for a bit, I'm
thinking that there isn't a water/oil interface at the head.  Am I
correct in this?  What other possibilities are there.  It still runs
strong - no noticeable performance issues.

I realize the Bronco II has a poor reputation, but he's had pretty good
luck with his, and would like to keep it rolling.

Thanks in advance,

Karl Wolz
