Smog system, should i run it or de-gut and plug??

[SS427]

At least 90% of the cars I restore have non working smog pumps on them. It has nothing to do with robbing horsepower but has everything to do with heat and moisture in the asperator tubes which will discolor and rust them out. On some cars I machine non smog manifolds to accept the asperator tubes but do not drill them completely through so there is no need to plug them.

I was basically going to say the same thing as Rick has this morning, but I got side tracked with outside work.

Thank you guys for your opinions on the smog pump and tips on the silicone.

Now how do i go about taking the guts out of the smog pump?
I remember finding a link to some web site years ago on how to do it but have since lost it or can not find it on google.
Anyone have photo illustrations or a link they can dig up.
Before i do anything i would really like to read up on it or view photos before i attempt this work as it is my first time taking this smog pump apart. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Tonight i gutted out the smog pump.
Followed the directions in the link and all went well.
There were 2 wings with 2 gears on each wing.
Two veins on each side that looks like magnet sticks and one shim on each side.
See photo of what came out.

To plug the manifold holes i will be using the factory extension tubes and cut them shorter and placing a stainless steel roofing nail on the top to plug the hole.
My buddy did it this way for his 69 Z28 so i copied him.
Tomorrow i will finish it all up and ad some high heat silicone to the top of the nail for a great seal [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
More photos to come.

Donnie,

Remind me to never buy a car from you [img]<<GRAEMLIN_URL>>/no.gif[/img]

Good move with modifying the smog system... It makes for less headaches especially by gutting the pump and most of all if your going to actually drive the car... The roof nail idea is clever.. A friend of mine machines little metal plugs that fall into the smog holes on the manifold and are machined with the exact bevel as the bottom of the smog hole so the plug seats right down into the hole then you screw the tube onto the manifolds...

JMO of course...

Hmm? Where did that come from Chris?

LOL It was a mid 80's van that had a new 350 4 bolt motor, all the accessories were ditched. (no vintage parts)
