83 GL Exhaust Spacers (Part of the ASV system)

[noahkort]

The spacers between the Y pipe and engine (which i believe are part of the ASV system) have warped prevented a good seal. I've read much about disabling the ASV system if the engine has a weber carb which it does. I do not know if it was converted or if it was factory. From what i understand some later 83s and early 84s had a carter/weber installed in the factory.

 

So i'm having them removed and intend to have them milled flat again, at a machine shop. can't find new ones anywhere.

 

I've read about disabling the ASV system with a quarter.

 

My questions are:

 

Can I disable the ASV system if the weber carb was a factory install or is that something you guys just do if you are doing the conversion yourself?

 

If I disable the ASV system can i leave those spacers out entirely and connect the Y pipe directly to the engine?

 

Regardless, should I disable the ASV regardless as a preemptive strike against it blowing up?

 

Thanks for taking the time to read, be well.

ASV system has nothing to do with the carb, its a stand alone system.  it doesnt hurt or help anything other than letting a little air into your exhaust for emissions.  If you have to emission your car put it back the way you found it.  

 

If you already have them out and plan on machining them (and you dont care about emission or inspection), id have someone weld up the holes and then reinstall the spacers.  Or maybe tap it for threads and plug it with a bolt.  that way your exhaust is still stock and doesnt have clearance issues, and you can remove all of the rest of the ASV system.  the quarter trick just fills the hose that comes out of the spacer, you can do way better than that if your pulling the whole thing out.

 

if they are warped you may want to watch your heat and check your temp gauge.  its always possible for a part to fail, but I doubt that warping is part of the natural life cycle of those, I bet they had to get hotter than you should let them.

I think what the OP was referring to is that a lot of people get rid of the ASV system when they do a weber swap, as is does share the stock air filter on all cars but 1980 when the asv had its own filter. It's part of the "emissions mess" that many do away with.

 

Also noahkort you might be confusing the weber-carter one barrel which came stock on some subies with the 32/36 weber which is the aftermarket one that people use to upgrade (this was never a factory carb).

 

That said the first reply has good info. If your car has the asv system you probably need it to pass emissions if you have inspections where you live. There are a few ways to cap it off if you don't want it, I use rubber bar stool feet to cover the tube on mine and put on a homemade filter when I run it through emissions. or use the quarter trick and one guy here pinches of the tube down by the spacers if i recall correct

 

You can get rid of those spacers if you don't need the system at all, but you will probably need to use shorter studs to mount your exhaust back up.

in a stock height situation, the exhaust won't clear the crossmember without the spacers.

i have left them in, cut the steel pipe that connects those to the rest of the system

remove all the other stuff, use the nuts from the end of the tube and a round piece of metal to block the hole in the spacer

i used the "donut holes" from our punch machine.

Interesting I didn't know that about the clearence issue. 1980 and maybe 1981 ea81 models did not have those spacers, they must have had a different bend to the y pipes on those cars that allowed them to clear the crossmember

Aye that has got to be exactly how it happened, we were stumped. I did have an issue on an 1800 mile round trip with some overheating. Tinkered with it between exits and was running hot a lot that trip, I'd repair one hose and blow another. I think i pulled over and fixed the car 3 or 4 times.  I had a pro look at it, we had decided to remove them and have them machined but when looked under it he discovered it was only warped on the Y pipe side and still were sealed nicely to the exhaust manifold. He was able to grind them down on the car and saved me the headache of carting the part around the state. Thanks again for everyone's input.
