Header leak

[rcb280z]

Anyone that has followed my "EFI relay unplugged" know that I just recently solved (with the forums help) most of my fuel injection issue. I now have an exhaust leak at the header. I hope it is just a bolt that has come loose from the head. Anyway, I hear it only after it has sat overnight! Hmmm...sounds like that could be my cold start problem! It takes about 2 minutes for the leak to seal and that's about how long it takes for the cold idle to work properly. Next item on the list....check exhaust/intake bolts.

Check the sprung washers as well.

Hey Rob,

Our friend Mike @ Sunwest Z suggests using 2 exhaust manifold gaskets when using headers.

Your right about that and usually I do. However this time I didn't have another one and had to get this thing together so I could smog and register it in CA. I knew I was taking a chance. I hope it's just a loose nut on one of the studs. It's not bad. Just don't want it to get worse. Good to hear from you Dan!
