Yes, the BCS foam is missing, no problem.
Yes, that'* a fiber gasket chunk laying there, but if you look carefulley at the Tstat housing, it looks like it was recently replaced. That may be debris left from the old gasket.

What concerns me is the vacuum connector on the far right, just to the right of the Tstat bleeder screw.

Yes the T-stat and all the rad hoses were replaced when I got the car, so that is probably where that gasket chunk is from. As for the vaccuum line, where is it attached on your guys cars? Anyway, after school I will look at the diagram and take some more pictures.

Thanks

Just follow the diagram...it'* super simple. I think that one heads over the TB to the evap purge sol on the bracket for the alternator.

Here is the best pic I could find at the moment of my '97. EDIT: 96 must be different than '97. I just went out to check and my evap canister hard line runs near the BCA and is attached by a tab to the head by the valve cover. I don't have a line laying where yours is. But, that definitely looks like the hard line for the evap can.

I found out where that vac. line goes. No where. If I follow it a little further it just ends, and the hardline it is attached to goes to the evap canister. It'* just there and does nothing.

I guess it is back to disconnecting the actuator and seeing if my boost returns.

Holy mother did I find my boost woes. I disconnect the vaccuum between the BCA and the BCS and plugged it. I went for a wot run and said oh **** has my head snapped back and the boost guage pegged right before the yellow part. I take it this is what was supposed to happen?

Why can't I just drive around like this with it disconncted? :P

You still need to hook that line from the evap canister to the TB where it belongs.

You did the BCS bypass and got your boost back. Your BCS is likely bad. I have one at home to check something, and I'll get back to you in this topic later tonight IF YOU PM ME A REMINDER. This is info I need to get into my SC page anyway.

Sounds good...I'll shoot you a PM in a few hours.

As for the vaccuum line, it actually goes no where. The bottom of it doesnt't come close to the evap canister, it just ends in the middle of no where. And there is no spot on the TB for it to hook up to. The hard line it is attached to goes from the evap canister to the evap switch at the rear of the engine, and thats all connected fine. This piece isn't even on the diagram. The hard line from the evap canister to the switch isn't fastened down at all which leads be to beleive the line was replaced from some other car and thats just an unused piece. I will take some pictures when my bro brings me my camera back.

Oh, and just a silly question, what is wrong with just disconnecting the BCS and plugging it and driving it? I got all my boost and nothing out of the ordinary was happening. I'm not going to do this, but I was just curious.

Also, I've been calling around for a BCS. I can get morad to send me one for $58 US (used). Theres a place locally offering me one for $75 CDN, and it is refundable if it doesn't work. What is a reasonable price?

A BCS last I checked was only about $30.

Running with it bypassed prevents the PCM from pulling boost when in needs too. Fuel mileage may suffer, but the real danger is if you run lean and the PCM can't dump boost via the solonoid. Very dangerous with nitrous, turbo, or supercharger applications.

BOOM.
