The biggest puzzle was the MAP sensor code, 13 or 37 or some such, if I recall correctly, that the car kept throwing. It turned out that there is a good reason for vacuum take off barbs to NOT be on the floor of the intake manifold; a slight amount of oil from the turbo would condense on the floor and drain down into the MAP vacuum line and make its way to the MAP sensor and foul it. The fix was, what else? - JB weld. I drilled out the inside of the 3/8" NPT vacuum barb to accept a piece of thin wall steel tubing (a piece of a golf club shaft), the open end of which then stood 1" above the floor of the intake manifold. With that stand pipe any oil on the floor of the manifold went into the engine instead of into the MAP sensor.
I would appreciate any recollections you might have concerning the car's build or history.
For instance, there was a piece of square tubing that was welded to the front motor mount and it ran back to and was bolted to the K frame, which tied the two together. I was forced to cut it off when I had to do something since it was welded, not bolted, to the front mount. Do you know what the theory or purpose of that was?
