mfa_mad_pig Posted April 9, 2014 Share Posted April 9, 2014 So I just did a Weber swap on my 84 EA81 wagon and I removed all the smog stuff. On the passenger side right behind the motor next to the transmission is this little cannister that had a hose going to the air filter. My question is what is this and can I remove it?

chompy Posted April 9, 2014 Share Posted April 9, 2014 The canister at the firewall? Does it look like a tiny can on it's side with an inlet/outlet? If so that's part of the vacuum system for your heater. You can plug that line directly into one of the manifold vac ports. Link to comment Share on other sites More sharing options...

No.....he's talking about the ASV and Anti-Afterburn system that was in those old Carbies..... To the OP......you can get rid of that plastic canister........If you want to plug the tubes off the exhaust that feed it.........unscrew the large nut on the pipe......shove a Quarter (the coin) in the opening and screw the pipe back in.........blocked off. You can remove those tubes and their base entirely if you want.....but then you gotta screw with swapping exhaust studs......and possibly extending the y-pipe or using EA82 one.

chompy Posted April 9, 2014 Share Posted April 9, 2014 Oh ya, I see what he was talking about now... Curious as to why he would have to swap exhaust studs after removing the tubing? I removed the metal tube and the rest of the asv and didn't have to mess with the studs in any way. Not to hijack a thread... Link to comment Share on other sites More sharing options...

On EA81 cars the tube that feeds the reed valves is mounted to a Block that sandwiches between the head and the y-pipe. The blocks bolt to 2 studs.....the nthe y pipe flange is rotated 90 and bolted to the block on the other 2 studs.. If you remove those blocks.....you have to move the studs to the other holes.....and use a EA82 y pipe cause the EA81 won't reach the head now. EA82 is not the same just remove tubes....block the ports ont he head. Link to comment Share on other sites More sharing options...

There was no need to remove the head or any studs... Link to comment Share on other sites More sharing options...

There was no need to remove the head or any studs... Not removing head. Removing the spacer block that the ASV pipes emerge from. It unbolts from the head.....but then to reinstall the exhaust.....the EXHAUST (not heads) studs need to be moved to the other set of holes The canister at the firewall? Does it look like a tiny can on it's side with an inlet/outlet? If so that's part of the vacuum system for your heater. You can plug that line directly into one of the manifold vac ports. If this is in your engine bay near the firewall you have an EA82 model car. What year? Link to comment Share on other sites More sharing options...

jonas Posted April 9, 2014 Share Posted April 9, 2014 Here's some pics. Hope they help. '84 GL wagon. http--,,--// http--,,--// Looks like, after removing the blocks/spacers, it should bolt right up. But, what things look like, and what actually needs to be done, are not always the same. Link to comment Share on other sites More sharing options...

chompy Posted April 9, 2014 Share Posted April 9, 2014 (edited) So with mine I just removed the asv tubing and blocked it with a quarter, leaving that in. Is there an advantage to removing the spacer/block? The upper end of the asv where the vac connects to was the section that simply unbolted off. Sorry again to the OP if this is no help to them...

Duh......That's what I said here..... To the OP......you can get rid of that plastic canister........If you want to plug the tubes off the exhaust that feed it.........unscrew the large nut on the pipe......shove a Quarter (the coin) in the opening and screw the pipe back in.........blocked off. Perhaps you didn't understand that. I was not saying any studs had to be removed for that part. Is there an advantage to removing the spacer/block? Not really....that's why I went on to say this. You can remove those tubes and their base entirely if you want.....but then you gotta screw with swapping exhaust studs......and possibly extending the y-pipe or using EA82 one. indicating the troubles associated......and why it's a PITA unless you are removing the exhaust for other reasons.

mfa_mad_pig Posted April 11, 2014 Author Share Posted April 11, 2014 Hey thanks for all the replies! Jono you are correct, that's exactly what I'm talking about. What is it and can I take it off? Link to comment Share on other sites More sharing options...
jono Posted April 11, 2014 Share Posted April 11, 2014 Um, if you do, plug up any holes it leaves behind in head and inlet manifold. When I first got my 84 Brumby, it had an import engine and this can hanging off one end and disconnected at the other with a bit of wood jambing up the hole - was enough to fool the rego inspectors. Sem to recall a spark plug may fit the holes where it comes out ? Inside may have been just a roll of steel mesh ? Link to comment Share on other sites More sharing options...
