Re: 5.0 Reply #1 – October 19, 2004, 08:12:06 PM i think it has something to do with letting the air cicrulate between the heads or getting them air from the air pump, whatever it was it looked at me the wrong way so i cut it off and welded it shut . along with removeing every other emmissions POS off the car after removeing all the junk i dont use, emmissions, ac, ect... theirs tons more room and i shaved off like 50+ lbs off the front.

Re: 5.0 Reply #4 – October 19, 2004, 11:29:38 PM huh...thanks guys. your car ran fine after blockin it off aye :rolleyes: i was just curious. its the only thing broken on the car and the motor is coming out in favor of a HO anyway. just about every sport i see has one of these broken or repaired. the last 3 mustangs i looked at had leaking headers. talk about annoying. why is that anyway...garbage...lol Quote Selected
Re: 5.0 Reply #5 – October 20, 2004, 09:30:58 AM It's a one-way valve that lets air from the smog pump into the heads via the pipe that runs across the back, and blocks any exhaust pulses from coming back out and ruining the smog pump or control valves. Quote Selected
Re: 5.0 Reply #6 – October 21, 2004, 09:02:37 AM Emissions junk. I cleaned all of mine out as well as getting rid of a bunch of excessive vaccuum lines over there. It's insanely empty on that side. Now if I can make the other side look nearly as empty, it'll be great.I unbolted the whole system (1 bolt on each head) cut all the excessive pipe off, welded the holes where I cut the pipes, and only bolted the small plates back on over the holes in the heads. If you go that route, make sure you cover the hole completely or your car will sound like a truck It'd probably be easier to line up if you left the cross bar in back. Quote Selected

No welding required. :D Quote Selected
Re: 5.0 Reply #12 – October 23, 2004, 02:47:57 AM Just a note from experience - I first ran my HO conversion with all emissions intact (except cats)then, in pursuit of power removed it all, then due to new smog testing I reinstalled it all (again - no cats, I just told the inspector my bassani X was a single cat performance pipe and he bought it!). I drag raced this car all three times and found no difference in et's bigger than .05 sec and the car runs better with smog stuff.Better mileage too. Not that I'm a tree hugger or anything - just telling it as i see it. Quote Selected
Re: 5.0 Reply #13 – October 23, 2004, 03:17:21 AM Easiest way to eliminate that mess, remove it all, plug the holes in the heads with old spark plugs (break the porselin off and screw them in, you might have to remove some carbon, but they will thread right in) Then pinch the pipe shut, as close to the exhaust as you can. Then all you got to do is remove the rest of the , either get an elimiator for the air pump or use it as an idler. makes getting to them pasenger side plugs so much easier! Quote Selected
