my 318 may or may not be a valid comparison but it also takes 8-10 minutes
to give me heat in the morning. I actually get about 5 miles further down
the road in the Dakota before I get heat than I do with the 7.3L non-turbo
International diesel in my Ford.

as long as we're talking about "what we've heard" I've read in at least two
places that almost all of our heads are likely cracked between the valve
seats. One article was on magnafluxing and the other on repairing cracked
castings by various methods. That one had some interesting stuff but I
don't remember any of the terminology so it might be difficult to find. It
was posted to DiRT a couple weeks to a month ago.

My original Dakota was a '93 3.9. I rebuilt the engine and one head was
cracked between the valve seats. The machineist sais it was very commom in
the 3.9.
