alright folks, I've opened up the new gaskets, as well as removed the old, and there'* some interesting notes...
pic whorage will ensue later tonight. but for a first crack, there is now a separate throttle body gasket, separate from the upper intake (which of course sucks, cause i'm not replacing the upper intake, so it no longer works with the gasket).
but that means, there'* a new upper intake on the way. right now SPO shows 2 in the entire country available for purchase, which was attributed to over-demand from dealers, but having looked at this new gasket for the throttle body, it seems like its meant to work in conjunction with a revised upper. not too different mind you, because the actualy gasket still matches in all the same ports. as it would, cause otherwise you'd have to replace the lower...
in any event, the question now is whether or not the throttle body gasket will pull out of the upper intake, or if it'* in there for good. i have my intakes sitting on the garage floor of theJMFC, and I'm not quite willing to pull the existing gasket out of the intake manifold, cause i'm not convinced it should really come out
in any event, pics will come soon. jr's3800, my upper intake is actually AC Rochester, along with the fuel rail. the manufacture date of the upper is 10/12/95.
the other thing - when i worked on someone else'* 3800 vin K from 99, i don't seem to remember the upper actually having a metal piece in it around the EGR - i could just be remembering wrong, but its deff. there on my engine, and I can guarantee that this thing has never been pulled apart before.
full pics, tech info on upper and lower replacement/rr will be coming shortly/w.in the next week or so -
