Hey,
I'm closing in on the 4.0 head swap and I am ready to put my intake manifold on it. I am using the stock intake manifold from an 87 258.
I may be showing my inexperience, but there is a tube running from the intake manifold to the exhaust manifold. I was wondering what it was, and if I still needed it. There is no place on my cherokee exhaust manifold (which im putting on my 4.0 head) to bolt this tube. Plugging it with a bolt was my first instinct (probably not a good one) so I thought I would ask first.
Thanks,
Joe

Do I need the egr valve with this swap. If I do how do I make it work with the exhaust manifold. Drill and weld a bung? Also do I need the 02 sensor? Emissions isnt an issue in the county I live in.
