If you don't find the leak then check your intake manifold for cracks.

ya its still has a vacuum leak somewhere. but gettting better. I took it apart( for the damn 3rd time) and i i had left some of the old gasket on. i figured its got be that unevenness, but damn that **** is so hard to get off. I pic at it for hours and get like 1/100 of it off. Also i heard that i need to keep the Crankcase Breather, when removing the solenoids and rack, wtf is that? Is it the black piece that plugs into the wiring harness and has 2 big vacuum lines on it? And there are no cracks on intake. Im starting to get very frustrated :( bout to snap.

I think i figured it out. Man u guys are really gonna laugh at me. I forgot to put one of the nuts back on that tightens the TB to the dyanmic chamber. It was underneath so i didn't see it. I also didn't torque down the bolt and nuts on the upper to lower intake manifolds, this time which squeezed out alot of the RTV gasket maker. I gonna let it really seal since its ******* cold up here. Then torque it down once the RTV turns into the gasket. I also did a little mod. There was a radiator hose that ran to the BAC, then to the TB, and off to the block. Instead i ran it directly to the block to clean **** up and make it simple.

It's probably better to just run the hose from the block directly to the water pump. That will; let you remove the BAC valve as well.



When you remove the coolant going to the TB make sure that the fast idle cam is either removed or disabled. Otherwise your idle is going to stay at 1500-2000 RPM.

Yeah i ran it directly to the block. i also finished the TB mod.

Which removes coolant flow to the TB; removes the secondary butterflys in the TB and the rod; and links the coolant hose directly under the upper intake manifold straight to the block. And it also removes almost everything on the TB

All i need now is some JB Weld to patch up the holes from the secondary butterfly rod.

I also removed the BAC. What all do i need to do, just unplug, remove & plug the holes? Is there any draw backs/gains?

Man my under my hood is lookin bare. Only thing left is to get rid of is the OMP & MAF, when i get haltech ofcourse :sigh: .

You could always just tap the holes and plug them up with NPT plugs instead of using JB weld. Yes, just make a blockoff plate for the BAC valve. It will make everything look alot cleaner.

thxs. what does the BAC do anyway? and how did coolant flow control the fast idle cam?



Heres a link to the TB MOD:

K2RD

Do i need to keep this piece? I see in comes in contact w/ the TB cam thingy. The fast idle cam and spring were underneath it.

The BAC valve controls the idle. There's some wax inside the TB. When it gets hot and melts the fast idle cam is disabled.

If you're going to remove the butterflies then remove it.
