Hello,

My van has developed a leak on the heads at the point where the nut to
tighten the heads down near where the spark plugs are. Also I think the
rings are gone and need to replaced, not to mention the rear main seal on
the crankshaft is leaking too. Just wondering on some advice on this
repair, is it worth doing on your own  to save the money? What kind of
special tools will you need? Any recommended places to get either new or
well rebuilt heads from? Also it would be nice to hear from people who
have performed this repair on their own before.

TIA,

Joe
