Thanks for the informative reply. Let me make sure I understand this
correctly; there are 2 standard intake valves on the intake manifold side of
the head and the aux. intake valve on the exhaust manifold side. Does this
mean there is an intake passage going across the head??

The Long Story:

Since I haven't found a need (yet) to pull the head off, I'm amaze and
puzzled by this complexity.

This whole car is new to me and only has 67,000 original miles, been garaged
all it's 20 yr. Really well maintained.

I was told it had a timing belt failure and possible valve damage. I bought
it with this assumption but soon found that the timing belt was fine and the
cam timing was exactly where it should be. I did cold compression tests and
found #3 was only 90# while the other three were 170-185#. I replace the
(missing) plugs and it started right up but rev'ed high (3500) for about a
minute. Finally idled down and ran smooth after warm up.

Initial road test were so-so. I did warm compression tests and found all
four cylinders were between 170-185#.

More extensive road test presented problems when the throttle was opened
more than half (before AT kick down). There was significant loss of power
and popping back through the carburetor. Part of this problem was traced to
broken vacuum hose (#28)coming off the throttle venturi. Repair of this
resolved the popping back and initially the car ran great on a 30+ mile road
trip. On return, while coming up a hill, as I depressed the throttle, the
engine lost power, like it was running out of gas. Briefly I could pull the
hill in second but when ever it shifted into 3rd gear, there was no power
again.

I still have a problem with it rev'ing high when first started and until it
is warmed up. Also runs ruff until warmed up.

Sorry this has been so long. Just though I would slip the whole story in
here.

Thanks,

Steve
