260Z exhaust manifold question

[felnik]

I've got this 260Z thats been sitting for quite a while. check out my last post for details. I'm in the process of accessing whether or not to get into it. Logic says no but the nut in me says go for it. Anyway, the car has triple Webers and I see this iron pipe coming up from under the manifold running parellel to the valve cover with little pipes coming up from the exhaust manifold. First of all what is this thing, is it emissions related? Its rusted pretty bad and would most likely leak like crazy if the car was running I can imagine flames blasting out fo the thing. what to do, what to do. any thoughts??

if there are tiny pipes coming up from the exhaust manifold area as I understand correctly , then yes those are emissions, they wouldn't shoot flames out but just sound like a bad exhaust leak , there are probably numerous threads on removing the emissions depends on where you live and the rules for older cars will dictate weither you can , getting a replacement exhaust manifold is very hard and if I were you i would replace it with a header <if you can> , if you look at my gallery the motor shown is a l24 but with the 260 n36 intake so it shows it without any emissions, if you have the flat top carbs you might have issues . good luck

Try this web site http://zhome.com/ if you haven't yet, alot of good info from alot of good sources I've emailed an article writers on IZCC about restoration guestions for the 260 we are restoring. May take them a few days to repond but they will get back to you you might want to get some good photos of your carbs There are books out about weber carbs, I have seen them on amazon and at VictoriaBritish.com. Hope this helps.

Would it be possible to cap off those tubes til I see if I can get the car started. its been sitting for 20 years in a barn. generally the car is in great shape but I want to get the engine started first before i spend alot of money just yet.

thanx

depends on where the leak was I was gonna try and use vice grips and clamp it down and fold it back but my leak was at the base of some of the tubes

Why not just get the engine started, THEN worry about those air injection tubes. Until you get the engine started you don't know if there is a problem unless you can see obvious holes in one or more of the tubes.

I'm sure there is a problem each end of the long tube is rusted through where the little ones join. IN any case I'm in the process of figuring out what I want to do with this car. I'm interested in starting to restore the thing but the list of things is beginning to grow.
