FYI : to remove old gasket, the easiest way is to get an air gun, with a wire brush attachment, and it will come right off...takes less then 5 minutes...

if you remove the BAC how is idle controlled? i installed the haltech and ran the coolant line straight to the block as well... my car is idling around 1300 RPMS...is it because of the fast idle cam? my car has always idled high for some reason...never idled below 1k RPMs....

I usually use a razor blade, or even a hammer and chisel. That works well, and is slow enough so that you don't get pieces of the old gasket flying into the intake manifolds.



My idle was always fine without the BAC valve. Your high idle may be due to the fast idle cam. Is it removed or disabled? You may also want to try adjusting the TB with the adjustment screw.

use an air blower and blow it all out until i read this post i knew nothing of the fast idle cam...so i assume that it is still enabled...

or you can also plug the holes with something as well... i used shop towels, and i used a shop vac to get all of the little pieces out before removing the towels...

If you're going to get junk in there it's better to remove the manifolds completely.

blah....like to take the long routes eh? hehe....j/k yeah it's always good to get it done completly right and not mess up... but i like shortcuts and I haven't replaced the gasket everytime that I have pulled the manifold off either...that would be over 10 gaskets already ??? I've only replaced it once...it hasn't needed a new one any of the other times I've pulled it off... that manifold has been on and off of my car so many times it's unreal...

Whenever I take shortcuts I always get burned. I don't replace the gasket every time I remove the manifold either. It can be re-used quite a bit, as long as it still looks ok.

There is a smoke generating machine that will pressurize anything and if there is a leak (vac,coolant,oil and exhaust ) it will show up. all depends how hooked up. I have a machine call Vacutech at my shop and I know Snap on sell something close to it. I have fround more vac. leak with this than i can count, and it is very safe.

My car was Running* it ran like **** though. Then i did the TB MOD, got rid of the charcoal canister, got rid of the BAC and removed all the old gasket. Now it will not run at all. Runs for lkike 3 sec then dies. what the **** is wrong with my car? i used a torque wrench on the bolts so its not them, capped all the lines on the Charcoal canister and used JB weld to plug the holes for the TB MOD and the BAC removal. There are no cracks on intake and there is a new gasket. WTF? :madgo: :madgo: I have checked recheck and tried ever fuckiong thing sprayin **** does'nt work. And yes it is vacuum leak. It makes the vac leak sound. PLZ HELP

I once had a hose that would come loose every time I put the manifold back on. That was frustrating.
