Jwfirebird, Thank you for the reminder about seals. I did replace the TB seal that had the all importnat seals for the coolant passages through the TB, but I didn't replace the MAP or injector o-rings. The MAP sensor on top of the PCV seems to have a good seal since the sensor requires some force to twist into place...but the kit does have a few O-rings left over so I will definitely look through them again and replace the MAP o-ring. For the injectors, I never disconnected the pressurized side...just lifted the entire assembly of 6 injectors still attached to the rails. But the kit also had the o-rings for the jectors so I'll replace those as well.
When I put in the LIM gasket, I used the black RTV that came with the kit for the left and right side flat gaskets(RTV'd top and bottom of those flat gaskets). Since there was still RTV left, I used a thin layer on the UIM gaskets especially around coolant passages. I even used the RTV to lubricate the 2 steel Dorman 47065HP elbows as well.
I had the Dorman 615-180 UIM for the job, but the mating surfaces to the LIM and TB were not smooth...had a lot of joint/seams from the mold from which it was made. Did Dorman go down in quality or did I just get a bad piece? Anyway, I re-used my old UIM since it seemed to have been already replaced by the previous owner...the stove pipe passage was in pretty good shape (not burned/disintegrated).
One question, after shutting off the engine, if I pull off a vacuum line (such as the one for the fuel pressure regulator), should I hear a hiss as it relieves the remaining vacuum? I'm not getting a hiss.
