So easy, even a caveman can do it.

I found your write up on SC removal but no luck finding the intake removal.
I assume the torque specification'* would be in there.


ill go through the list one more time

ahhhh, I did a search on intake removal I see LIM would of been the better option thanks!

well the write up from Danthurs is detailed enough to make me feel comfortable to dig in on my own. ill let you all know how it goes in 4-6 weeks, when my cast comes off I will begin to tear it apart

could always come down here if you wish, I wont charge you to much.

at this point I cant even afford the gasket set and miscellaneous items, should get my W2'* within the next couple of weeks. I would absolutely like to take you up on that offer.

who better than a certified bonneville nut

you can drive down by me and i wont charge you a cent

Usually when I see a leaking upper plenum, I prefer to change the intake itself out. I figure the gasket is about 75.00 itself, and the whole deal from carquest is about 127.00 or so and it comes with a new gasket. It also comes with the EGR tube modification to prevent them from melting threw and flooding and hydrolocking the engine up.
Just my .02 cents. It sounds like you have a external leak from what you are saying although you could possibly have both. It could be leaking externally and also leaking into the engine. But usually when its leaking internally there is a mis at idle and most of the time they just go without much of a warning. I would also carefully examine the area around the egr tube when you pull it off and look closely for any pitting around the 2 coolant ports. This will cause problems for you, if it is pitted, make sure vehicle is in in a heated area and use a cold weld or jb weld on it and fill in the pits and then later on after its cured sand it off with a really fine sand paper and then make sure to do the egr tube mod and reassemble. I know there are some cheap new upper plenums on ebay, but i never bought one so I don't know the quality or if i would trust it

This is on a SSEi, no plenum.
