First off, a quick thanks to everyone who helped with my grinding
driveline problem. I ended up oiling and greasing the bejeezus out of
everything involved and am waiting to see how it helps -- while ordering
extra bearings, scoping out a local shop that can *properly* remove the
hub if need be, pricing a new axel or hub and upgrading my AAA membership.
Haven't got up the courage to do a long test drive yet, but on short runs
the grinding is back to a I-might-be-imagining-it level again. I'll
post an update the final resolution once I'm pretty sure I know it :)
Next task: getting pass smog control. Six thousand miles ago, under the
DPO, emissions were well within acceptable levels (I have the WA smog
cert.). Now, they are *very* bad with high HC's and CO ten to a hundred
times what they were. Of course, with 20 mpg I was expecting exactly that
(I'm a combustion major and knew all that energy going in had to go out
somewhere, and it certainly wasn't the wheels!) and am embarking on a carb
rebuild at the moment, expecting to find an oval hole where there should
be a round one (the needle hole -- "the jet"?). Has anyone ever tried
kludging a fix to that? Displaying my utter lack of carb knowledge, is it
possible to have the hole bored oversize and use a larger needle? (been
following the recent carb thread -- very nice I must say).
My next question has a visual aid, what is the thing shown at
http://weber.u.washington.edu/~tyre/pics/arrowed.jpg (picture is courtesy
of Sam Gentry, and is what I wish my spit looked like -- I have a bolt
blanking off a hose where said thing is). If you don't want to check out
a picture, the best I can describe it is the thing plugged into the top of
the intake manifold that isn't the anti-runon valve vacuum line-- the
manifold connection is almost symetrical to the anti-runon connection,
molded into the runner that splits and goes to the two cylinders closest
to the firewall. Am I correct in thinking that it is (should be) the Air
Injection System diverter and relief valve?
My car has just a blocked off bit of hose coming out of the intake at that
point. As a 1980 Federal emissions vehicle, should I even *have*an AIS
manifold? I don't see any holes in the engine block for such a thing to
plug in (block# 312240). My air pump simply dumps into the exhaust
manifold a few inches above the connection to the cat. The "Repair
Operation Manual" for the Spitfire 1500 in section 17.25.17 suggests this
is right, that later models don't have the whole (no longer easily or
cheaply available) air injection to each port manifold and incorporate the
diverter valve into the air pump, yet I have this blocked off hose without
a use sticking out of my intake manifold, and a picture of a 1980 spit
that appears to have something there... Any help on what bit(s) I'm
missing? Or am I OK, with a later model Spit that didn't muck about with
all this CA sh'tuff.
And, as a rhetorical question, how the heck can I fail smog for missing
emissions equipment when they can't tell me specifically WHAT I'M MISSING?
Maybe if I simply cleaned up that sloppy looking plugged hose they'd never
notice...
Thanks for any help (and/or sympathy :)!
