Well ... I got the EM studs reinstalled on the ur last night. The major
problem was getting to the lower stud on #2 (it's tough to get anything in
there that doesn't interfere with the turbo). Over the weekend I found
that SK tools makes what they call a "Roto Ratchet" The ratchet's handle
pivots about the center of the ratchet mechanism. It is very similar to
having a ratchet mechanism built into a universal joint adapter. I man-
aged to get a deep 6-point socket connected to the ratchet in there to
tighten the nut. The ratchet also has a 72 tooth head, giving 5 degree
The SK part number for the Roto Ratchet is 43875.
BTW ... I too saw the big throttle valve bypass valve buried under the
FI & intake plumbing on the QTC. It looks to me as though it is meant
to be some type of decel bypass ... the valve is controlled by manifold
vacuum. It is shown on the vacuum plumbing diagram on the hood, but the
connection to the IM was left out of the diagram. I also noticed that
there is another, electrically operated, bypass valve which is apparently
to increase the idle speed when the A/C is on.
I got the engine running last night ... no more exhaust leak @ the EM!
Now all that I need is to adjust the valves, get the car smogged and I
should be back on the road by this weekend! <Vbg>
