The only way I know of is to ask the seller to have the engine cold when you
arrive, and check the water level. Then take it for a good run to get
everything to normal temp, return to base, let it cool down and check if it
has lost any. Significant water loss, residual pressure in the system,
overheating on the test drive are all bad signs. The only way to know for
sure is to take the head off and look, but water level is a good indication.

Bear in mind that even if it's a bad'un, there are solutions - new short
engines aren't ridiculous money, and someone (ACR?) does top-hat liners that
cure it - PROVIDED that you get the car for a price that factors this in.
If not, keep looking - there are plenty about, and going for daft money in
some cases. Also, remember that although people bang on about this problem,
it's still not common. I bought my P38 at 43K miles and sold at 87K, and it
never overheated (even towing a caravan across France in a heatwave) and
never used a drop of water.

If you get a good'un, it's a brilliant car. Did the RRC not turn out as
well as you had hoped?

I'll second that, especially the bit about being cold initially. You can
also whip the plugs out and look for one that appears considerably cleaner
than the rest, much the same thing as lifting the heads and seeing one
piston that appears "washed" clean with very little carbon. You could always
borrow some sort of endoscope thingy and look into the combustion chambers
for signs of washing...??

Remember though that the system will be pressurised even if the engine is
perfectly good.

Also available from Lund Engines down in Devon, and most likely any other
decent engineering shop almost anywhere else in the country, as the liners
are available readily. Be warned though, an exchange top-hat linered bare
block only will set you back ฃ800+. If you find anyone doing them cheaper,
please let me know!

Maybe the suggestion was to let the seller know that was likely to happen if the
specified fault was found!

especially, in fact. It's designed to be pressurised.

it's when it pressurises to the extent of blowing coolant out that you have
troubles...
