My gf bought the ebay turbo manifold for her MSP, since her stock cast mani cracked after having been previously rewelded once before. I am having an issue with installation, everything has fit nicely up to the point of actual placement on the head. What exactly should be done about the EGR tube leading into the side of the manifold. It appears that the nut should be threaded onto the new manifold but the the threading from the tube is attached the nut. Does the nut separate from the threading? Is it possible they may have just rusted together and can be broken loose? Sorry if this is a simple question. I am Speed6 guy so I just simply blocked off/removed my egr system all together. Thanks for the help!
