The car's taken a second or so to shutdown ever since I got it about
nine months ago (wow the time flies).
While running heav's suggestion of the miracle oil in a tank of diesel,
the shutoff completely failed to function. It didn't shut off the first
day, then that night it got pretty cold and shut down after a couple of
seconds, and it hasn't shut down by itself since.
So today I finally got to looking at it. First order of business was to
hook the ol' MityVac up to the shutoff valve. Let's just say I should
have used an older hose 'cause the shiny new one is now full of oil.
Obviously, this puppy has gone bad. My questions, then, are thus:
It appears that I need this part, and gaskets are available separately,
which add another $1.50 to the price so I might as well...
However, this guy is right nearby in the schematics, but I'm not
following what it's for. It says "from engine no. 93508", but as of yet
I've been unsuccessful at locating the engine serial number. I know
where it's supposed to be, and I see a string of numbers that contain
'617', but the numbers are otherwise non-sensical to me. Anyhow, this
guy's almost $200 and I'm really hoping that it's not a critical piece
of the puzzle.
Finally- when I do this fix, how critical will it be for me to replace
the vacuum line to the key? I'd really like to avoid opening my dash
up, especially considering the manuals talk about pulling the cluster
rather than accessing it from below. I guess it wouldn't be the end of
the world though since I need to replace my idle speed cable at some
point anyway. Oh, and until I get the parts and get it fixed, should I
just run with the vacuum line disconnected so I don't continue to suck
oil into it?
I'll wrap with the following fuel update: over the past 1700 miles I've
put only 13 gallons of petroleum-based fuel into the car. Most of the
rest of the fuel has been "virgin" soybean oil, but as of last week I've
got my filter and pump and set of 55 gallon drums setup all in order and
have been pumping used veggie oil from a couple of local restaurant
friers. The car runs super smooth on this stuff, which is unsurprising
because of the lubricity of vegetable oil (and the fact that even 5%
biodiesel can return pump diesel to the same lubricity that it had with
all of that gnarly sulfur).
thanks, as always. You guys are great.
