The next generation are eschewing bleed air driven pressurisation
and going to seperate supercharger systems. A lot of older
turboprops used this system as well as a small number of jets.
The 787 will have this system. *

The B-707 had both Bleed Air and Turbochargers. We used the
Turbochargers most of the time. An engine bleed line spun a
turbine which then turned a fresh outside air compressor.

Yeah, that was the jet exception I had noted. You were lucky you
didn't have to breath the compresser section air in that thing!
The JT8 was OK AFAIK There would have been some fumes, but the
RB-211 is a complete piece of junk. The Brits never could build an
oil tight engine....

Thats why you never change the oil in a british engine, *you just
change the filter every 6000 miles, with the leak and replace of
the oil, oil changes are just a waste of time.

True, and they actually don't change the oils in RB 211s either! That
is part of the problem. As jet oil ages it gets thinner and leaks
more easily, and it also gets smellier.

Is there a link other than a common country between the engine makers
and Austin Healey cars? The AH I had positioned the distributor
exactly where water would splash when I drove through a puddle. There
was no need to put a top on that car, if it was raining it wouldn't go
anywhere anyhow. But it would leak! It was the car I owned that was
both the most trouble and the most fun to drive.



They're worth a lot of money now!
I got a rubber boot to go over the distributor on most of the brit cars
I owned. It did help a lot. Just had to replace the cap on my VW for the
same reason. Must be twenty years since moisture stopped a car of mine..
