1930 V8 Manifold problem

[Cooke]

I posted this under the General discussion, no luck, any ideas are appreciated.

I just installed a new manifold and cast iron y pipe to my 1930 V8. I have a slight leak at the manifold-y pipe junction. Its just a very tight slip fit with no way (that I know of) to tighten it. Any suggestions??

Martin, If it is a slight leak you can pull it apart and put high temp RTV on the joining parts and put it back and let the RTV set up. Do you still have the original inner pipe joining the pieces together? If so the RTV should work. If you are not using the original inner pipe you can use an exhaust pipe expander along with a nearest size piece of exhaust pipe expanded out to a tight fit along with the RTV. Good Luck Harry
