[AJD] 35 D Runs Again!, but CRACK?

[Gary Epps]

Greg,

I'm keeping these emails in my D file so if I  need some help with an
unrepairable head I will contact you.  I'm thinking the problem may be in
torquing the head bolts.  I will try a new torque wrench when I can bet back
to it.

> In my experience and after fielding many many phone calls, I have found
that the D head is notorious for cracking. I would highly suspect a crack in
the valve seat area. A crack into the push rod tube area in the block ill
also vent large amounts of water quickly. All things considered, I would
hope for a cracked head as those are usually repairable and you don't ahve
to tear the entire engine down. If it is the head and you can't find anyone
to repair it or if it's been diagnosed as unrepairable then contact me and I
can give you a guy's name who specializes in repairing the unrepairable,
might be worth a shot.
