Richard,
I hesitate to write in here, since I am so new to the DeLorean, but 
I'll contribute what little I know.

Another possibility to consider. The engine is set up with cylinder 
liners, and a path to get antifreeze into the oil pan is via the seat 
between the liner and the block (upper crankcase). In my engine with 
54,000 miles, I had some serious corrosion on the #3 and #6 cylinder 
liner seats - down to less than a tenth of an inch for the paper 
gasket to do it's job once installed. I decided, with the advice on 
my machine shop, to install the cylinder liners with the appropriate 
RTV (I'll let you know how this turns out), instad of replacing the 
block.

>From what I can find, failure of the cylinder liner at the seat isn't 
real common on this engine, but I had a water cooled vanogan with the 
same cylinder liner set up, and an exhaust leak around the head 
gasket or via a crack on the base of any cylinder liner caused all 
kinds of problems with overpressurization in the hollow portion of 
the block (where the antifreeze is), including casuing the water 
bottle to explode. It will take the path of least resistance.

An easy test for this is available. You can get an additive to add to 
the antifreeze and if exhaust gasses are present, the antifreeze 
changes color. 

Since the engine is all aluminum, I'd tread real lightly. Sounds like 
you may need to disect anyway. Any good machine shop can check the 
true of the engine and suggest a course of action. 




For what it's worth,
