Okay removing the smog pump today of the 96 5.0.. I'm just putting a smaller belt on but I've read around and once you remove the pump and the charcoal filter by the battery what are the holes people talk about plugging, can someone give me a step by step walk through on removing it

 

The charcoal filter has nothing to do with the smog pump/AIR system. That is for the fuel tank vapors. The holes you are referring to are in the back of each cylinder head. There is an external cross-over tube that connects them together with a check valve on top of it.

This assembly looks something like this:


Once you remove the cross-over tube/check valve you need to plug them with something like this:

The plugs are simply a 5/8" bolt 3/4" long.

In the pic above the shiney tube that goes to both heads. You can see the blok a the end with the bolt on the left side of the pic. Well if you remove the bolt on Both sides under the little block is the hole that the 5/8" bolt fits into.

I believe it's 5/8" might be 3/4" tho... Either way 2 bolts are cheap lol

 

Any problems if I don't plug
The holes?

 

Bad exhaust leak if don't block em off.

 

What he said^
The exhaust would be directed directly at the fire wall causing it to got very warm possibly causing issues and it would be loud.

 

Am I forgetting something? Okay if your faceing the engine and on the passenger side the actual smog pump is the part of the belt route correct? And off the back of it is the metal tube with the black bulb and it's goes towards the back of the motor.. And behind the battery is the charcoal filter then behind that is either the soup can deal or the black plastic vacuum box.. Am I right with what the stuff is?

 

Charcoal filter is mounted down on the frame rail next to the battery. LEAVE it there. Why exactly are you removing the smog equipment off your truck?

 

The black can behind the battery that had a tube running off the smog pump is gone, and the vacuum box behind that that had two vacuum hoses connected to is gone and the vacuum hoses are plugged


And my cats are gutted, so the pump isn't really serving a purpose, plus I'm getting ready to rebuod the motor

 

Seems to me it's a good idea to keep the vacuum can (soup can) its like having a tank for an air compressor...gives a constant vacuum

 

Well the vacuum is on there now... But the charcoal filter is gone

 

So now you get to smell the vapors from the fuel tanks............

 

You can plug the hole on the manifold or you can get fancy with one of these. I ordered the wrong size so I have one in my tool box. They come with very good gaskets, metal center with fabric on each side.
