I'm having a problem. Every time I post to the list here, I don't receive
the next digest. Consider this a test, and please forgive me if it
appears that I don't respond to follow up posts. I'm not seeing them.
Anyway, Dennis Wilson was the first person to get a totally correct answer
to me (directly) on the headscratcher question. Jerry, Phil, and Roger also
got close, but too late. Here it is:
>Well how about this: Water has a specific heat capasity of about 4.2joules,
>or something like that, now antifreeze has a different SHC (Lower I think),
>(nop, change my mind, higher i think) so it would not absorb heat as well
>in the head so the comb chamber would get hotter than with lower concs of
>antifreeze but the temp gauge would still read 180 because the cooling
system
>is doin its job but the volume of coolant in the head with 70% antifreeze
>cannot conduct enough heat away for the time is spends there.
Also, Dennis, I'll check tommorrow to see if I can find the Spit motor listed
in a machine shop guide I have. It ought to give all of the data on the
cam and cam bearing sizes.

I was going to say not here at home, but a quick scan of my book shelf
turned up an old AutoPress MGB manual (63-73, it's old!). On page 115 it
pictures an exploded right brake, and on 116 it shows the assembled left
brake, both as I described them. (whew :)

As explained above, no I didn't see it, unforch.

Yeah, I meant the Renault powered cars. They are much more subseptable to
small air pockets in the cooling because of the classic French engineering
of putting the water pump at the top of the cooling jacket rather than the
bottom. I've never figured out why they did that, and *kept on* designing that
way even after the flaw was obvious.

That particular car was really my father's. He got it in 74, and drove it
daily for a while. Then he started tinkering, and fixing, and re-engineering,
and prettifying, and ... The car got so "perfect" that he wouldn't drive it
much. So, he sold it and got a 41B (old F2 version). This we auto-x'd, until
he started fixing it up. That got too pretty, so was sold, also, and replaced
with a S1 Elite. When it was pretty enough, it got sold, and he bought a
super seven twincam. This car is currently perfect.... and for sale. There's
a pattern here somewhere, I just know it. BTW, anyone have a lead on a medium
condition turbo Esprit? (the non-fed Essex edition that keeps popping up in
the northeast has already been considered and rejected, because of being
non-fed)

Really, with the cars discussed here most, grease *everything* often!!

>brakes. Right?
I'm going out on a limb here, but I believe that the brakes on the Europa
are bigger. Either Herald or Vitesse. All of the British drum brakes I've
seen go together this way. My experence only goes back to the MGA and BN6
era. I don't work on cars older than me. :>
>"Over-opinionated"? By whose standards? This list can't work without lots of

Well, I pass all out going mail through a halon filled nomex filter. That
gets rid of most of the *hot* flames, anyway. Athough... some say I should
trash that and just use a spell checker like other people.
