what sort of cruise control do you have, and why is the consumption better
with the cruise control?

I don't know if it's a regional variance but my 240 (1983) has a 60L
tank. The car was built in Sweden and sold in the pacific northwest US
somewhere (Washington State I believe).

Bit of a contrast to the '88 I just bought for AU$200.  :-)

Very straight body but faded paint, an engine that allegedly uses lots of
oil (but didn't on the drive home) and a bit of trim damage in the
interior.  A very nice straight body, though.  Looks to be totally rust
free but I'll find out for sure when I pull it apart...

Should be a good new home for the 350 chev, etc. that are currently in my
'80 264GLE.  :-)

It's in the oil filter. Helps keep residual oil in the filter to stop the
engine running dry for the initial second or two.
Flame trap is a small plastic part with holes in it for the crankcase
vapours to pass through. The idea being that if there is a fire ball in the
crankcase venting system it will break the fire front up and extinguish the
fire there by stopping a blown seal or two and a fire. It is a "dirty" part
and when it gets blocked you get high sump pressure which can cause a number
of issues. Including blowing the rear engine seals. It's a cheap part and
can normally be kept clean with a small amount of maintenance. I bought
several years ago and have only used two of them. IF it get's really dirty
or messed up replace it. Also replace at the first sigh the plastic is
ageing. It IS a bastard to get to it as it's right under the manifold. Once
you get the hang of it you will be fine. There are a few good Volvo web
forums which you should look at for more detailed information.
http://brickboard.com/ is one BUT there are a few very arrogant and idiotic
people. If you run across one don't be turned off of them. Not everyone who
claims to know something does. FYI I'm not talking about anyone who posts in
here :) You should also consider buying a decent manual if you wish to
maintain your own car.
