After 300+ photos I still failed to capture where these go on my 88GT. I have two photos below. Can you mate 1&2 and A&B?

Here is the firewall


Here are a couple of ports on the firewall side of the engine I think they go to.


Double bonus question- "?Where does this go?" The fresh air pipe along the back wall has a large and small diameter pipe. Where does the small one lead to on the passenger side?

1&b ------ 2 you're supposed to have a metal tube there that goes to the Throttle body on side of the big rubber hose that goes to the air filter
A has to be plugged was part of the recall was were the 2 is now

The vacuum pipe leading to the bottom of the throttle body is a single pipe between the lower manifold and the TB. The rubber hose between the air cleaner and the TB has no inlet on the side. So it appears this never got the recall performed?

What about the double bonus question??

Thanks, Robert!

For the "Double Bonus" if that line is going to a nipple on the air cleaner can, then it's a "fresh air" source for the EGR solenoid.

Yep, b goes to 1, that's the vacuum for the power brake booster. This appears to be a car that the PVC recall wasn't done on, so a goes to 2. On recall cars the rubber hose on B was removed and a cap put on the steel tube, then a new steel tube was installed that ran from 2 over to a new rubber snorkel connecting the air filter housing with the throttle body.

If by "back wall" you mean the forward firewall, then the small diameter tube labeled "Where does this go?" in your picture connects to the forward end of the EGR solenoid with a length of rubber tubing. It is a fresh (but not clean) source of air for the EGR solenoid.

james has those backwards.
1 to B
and 2 to A

I believe B goes all the way up front to the brake booster or something.

OK got it.

Pipe 2 goes to hose A- This supplies fesh air in to the valve cover. The car did not get the recall done. Is this one of those senseless recalls and do nothing or should I be looking for the recall parts?

Pipe 1 goes to hose B- Hose B leads to the firewall. What is it supplying vacuum to?


Double bonus question- One end to the base of the aircleaner. The other goes to EGR solenoid. I understand.

Thanks for all the replies guys

bump

Hose B should be supplying vacuum to your brake booster.

JazzMan is correct....

Is the recall on the fresh air to the valve cover something I need to get done? Or is it another one of those recalls that were a mistake?

None of the recalls were mistakes, though some were more effective than others. The main purpose for the PVC hose routing recall was to deal with problems of oil vapors condensing inside the tubing and running downhill to accumulate in the air filter housing. The new routing puts the tubing at the high point such that most condensing oil runs back down into the valve cover.

Doing the vent tube recall will help keep the inside of the air cleaner oil free. There are only a couple parts needed to do it. I'll look and see if I have any of them left.

I found the part. It is a replacement snorkle and a tube that goes from the snorkle to the valve cover. $20 shipped if you want it.

And by the way, that is one darned good looking engine.

Hey Aaron,

Thanks for the compliment. I am so glad I had you powder coat the intake and valve cover. You did a great job on them.

I would like to take you up on your offer on the parts. I have sent the $20 via paypal.

The parts are in the mail.

Thanks Electrathon!

Electrathon, I got the parts. Thanks! I am unsure how to mount the tube between the snorkle and the valve cover. It has a mounting bracket welded to the tube, but I can see where it should be mounted on the car .

Any hints?

I think,this is what your looking for...
It's held on, by one bolt, on the engine block side.

Ignore the rubber hose,I used to cover the tube.It realley has no purpose.

That's exactly it! Thanks for the pic. I understand.
