Posted July 5, 200420 yr comment_87530 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??jf Link to comment https://www.classiczcars.com/forums/topic/12487-260z-exhaust-manifold-question/ Share on other sites More sharing options...
July 5, 200420 yr comment_87531 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 Link to comment https://www.classiczcars.com/forums/topic/12487-260z-exhaust-manifold-question/#findComment-87531 Share on other sites More sharing options...

July 6, 200420 yr comment_87651 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 Link to comment https://www.classiczcars.com/forums/topic/12487-260z-exhaust-manifold-question/#findComment-87651 Share on other sites More sharing options...

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.

July 7, 200420 yr Author comment_87745 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.
