Don't worry Chris,
The engine hasn't been fried ever, unless
you count the first time the coolant overheated and blew out the expansion tank
top. Since then we've just tried to bleed the system properly, but to no
avail. Believe me, since it's first coolant
blowout, I've been careful not to overheat, even while just quickly
turning the engine to check the coolant was running through fine. The engine
runs fine, with a very clean engine sound. I'm still unsure about those
wisps of what looked like exhaust gas around the left hand side of the engine
though. It may just have been evaporating water on the engine from a recent
clean that day, still not sure though, was hard to tell. There's nothing
at all wrong with the car, except for the overheating coolant system, whichI
am sure is down to bleeding the system properly, and keeping it that way, and
making sure that the fans kick in when they should do. I'd had long waits in hot Devon traffic
jams, with no over heating at all, then on one trip it over heated(after
driving for only 15 mins or so). Since then been
difficult to bleed the system properly. Martin and I will get it sorted I'm
sure, if not, I'll let the diesel centre have a go, but that really is a
last resort, as cash is not flowing right now.
We
will try the following:
Fit
bleeder kit.
Enable
Fans Full time
Run
Coolant System fix through system, to stop up any leaks for now.
Check
before the above, if exhaust gases are escaping, and where from
Look
over the car in general.
We'll submit a report of how things
go, but I'm sure I'll be up and running by the end of Wednesday
night. Wish us luck!!
Stephen.

Martin, to a visit, and the bleeder kit if possible... .
I will check all the electrics and fit the self bleed
kit (which I DID leave at home in Kent - DOH!). As to diagnosing the overheat
problem, I will ring Jason tomorrow and ask his advice. I'd also like to see
this exhaust leak myself (apparently it's not accompanied by a
"beetling" sound).
Rich's gaskets were so bad that the coolant leaked out
from the heads, (though it was established the gaskets had never been allowed
to "bed in")

A good
mechanic should be able to tell if its the manifold / ex sys or head blowing.
I've never seen a head blowing "Externally", normally they mix upoil
and water...water and oil..misfire..but then again I've never fried an engine....several
times! It really sounds like a job for Mark or the Diesel Centre....I
don't like the sound of it at all!I can only repeat what I said months ago,Fix
the temperature gauge, check otter switch, check the fan fuses and heat sink
thingy..this is all basic stuff.Chris P

(mostly for everyone else, Steve and I spoke this
lunchtime)
The self bleed kit is a barbed T-piece, a lengthof
hose, several jubilee clips and a fitting which has the same thread as the
bleed screw on the water pump, and a barb. Basically you replace the bleed
screw with this barbed fitting, and route it via the hose to the coolant bottle
return hose, and T into it with the T-piece. Effectively the water pump is
continually bleeding itself.
Chris, once again I know the kit's really really
simple, but finding the fittings is the bit I haven't had time/can't be
bothered to do. Andy asked me to get him one even though it's priced up at 10
times its actual value (but $20 hardly breaks the bank, eh? :-)
I ain't no expert! I know me 'lectrics and I'll check
the cooling fans are working (sounds like they're not) and rig them so they
work with the ignition. The combination of the self bleed kit and the fans
running constant should do for now, but from what Steve said about escaping
exhaust on the left bank that's NOT the manifolds means I'm starting to think
"head gaskets" - anyone else concurr? If it's been allowed to
overheat several times, the heads will warp blowing exhaust into the coolant,
causing air-lock and overheaing = vicious circle. AM I WAY OFF HERE??
I am no expert, but this makes sense to me. How on the
DeLorean engine do you know if the head gaskets are blowing? On the BX you look
for bubbles in the return line to the coolant bottle. On the DeLorean (without
the self-bleed kit) they all get stuck in the water pump, right?

When could you
come down this week, I would really appreciate a visit? Could you come
Thursday? Would be the best day? I would advise to come prepared with
electrical bits and bobs, as I think we'll need them. I would be really happy
if you could let me order another bleeder kit for Andy, and I use his for now,
given that my deadline for the car running is very close now. I would be really
happy for you to look over the car in general, to see if your professional eye
picks up anything I missed. Anything you think you would need to fix likely
problems, bring it, as I have nothing up at the house L I would love to think I could have her up and running sweetly by
the end of your visit J Hope you can make it, with bleeder kit etc, regards
Stephen.
