My wife's 89 V 12 lost a radiator hose on the freeway and heated the motor
pretty good.
I had to remove about 0.030" from each head to get them flat and replace
some valve seats that loosened due to the heat.  Also found quite a bit of
corrosion on block and head surfaces which I filled with JB weld.  This
happened at about 50,000- car runs strong now with the new 3 angle valve job
and shaved heads.  Did all the work myself, but the gaskets, valves, seats
and all new radiator hoses and metal water pipes set me back about 700.00

Overheating of the V12 often results in extensive engine damage. The valve
seats can come loose and this can destroy valves, pistons, heads, and
cylinder sleeves. I have an overheated engine in that condition. The rings
can loose their tension from overheating as well. I would consider an
overheated V12 as in need of engine replacement or complete rebuild, though
the damage could be much less. There is no real way to know until the heads
are removed.

Suggest you not be tempted by this 14 year old car's relatively low
purchase price. That's usually a fool's bargain when it comes to luxury
cars - SEEMS like a bargain but will be the MOST expensive car you could
buy. We all WANT to believe the repairs will be minimal and so avoid
recognizing the true cost of such a "fixer." This repair is open ended,
labor intensive and uses parts with limited distribution; all guaranty a
high repair cost. And, as its owner, you'll have NO CHOICE but to pay.
That's why it's For Sale!

Don't buy someone's troubles. Rather, if it MUST be a V-12, look for an
"expensive" car that's so because it really IS in top condition and can
pass a mechanic's pre-purchase inspection. Yes, you'll feel like too
much was paid BUT that car, given proper maintenance, won't fail you.
This approach recognizes the true cost of luxury car ownership.

Buy a bargain "fixer" after you've owned some Jaguars and know your way
around the repair shops and parts sources. You'll then be able to assess
a car's repair needs and the approximate cost of such work. A new owner
lacks such insights.

Hello All,

Thanks for the advice and everything.
I think I owe it to myself, and newsgroup contributors, to go and take a
look at least. I'll be happy to put up some pictures when I have them,

Regards,
Stan
