RE: [DML] white smoke - cracked head?

Stephen - I'm doing the same  job myself, started last night.
I used a cooling system pressure test unit borrowed from auto zone - in
addition to white smoke I found that pressure begins building in the
cooling system in less than a minute on mine.
Look at the write up at DMC news - go to and click on the
technical info link for Cylinder Head R&R.  It reads a little daunting
the first time thru, but its a good description so far and I expect few
The tech manual has much of the same information, read and understand
them both and you are well on your way.  Email me off list if you want
to compare notes.

Subject: [DML] white smoke - cracked head?

Hello everyone, here is a little background and a
multi-part question.
We bought our Delorean earlier this year, non-running,
and have been getting it ready to start, freshing up
the cooling system, fuel system, ignition system,
fixing broken wires, and so forth (I had the gas tank
cleaning question last month). There is some evidence
that it had gotten hot, rear fascia has some heat
damage, as well as heat damage on some wires by the
exhaust. We finally started it this past weekend, and
it runs great, except for one issue. 
When we first start the cold engine everything is just
fine. As it starts heading up it starts belching
white smoke, quite a bit of it. I think what's
happening is that there is a crack in one or both
heads, as the car heats up the head expands and the
crack opens up, water gets into the combustion
chamber, voila, white smoke. Does that sound
reasonable? Could it be something else I hadn't
though of? Maybe a compression test would help
verify, but maybe not since the crack is small when
the engine is cold?
I have a good place to work, tools, the job doesn't
look horrible, and I'm pretty good in the garage so
I'm comfortable doing this job myself. Any tricks or
advice? Can you get aluminum heads repaired easily
and reliable or should I look for replacements? Can I
get heads off an Eagle Premier or other prv equipped
car (I think there is one in a local pull-a-part)? If
not where can I get Delorean heads?
Thank you in advance for your help.
Steven Clark
