    95 5.0, has the stock exhaust manifolds. Previous owner deleted the egr and plugged the hole in the passenger side exhaust manifold with ****ing aluminum foil. I want to put a plug in it so it doesn't leak. Does anyone know what size plug that hole is? I think a brass gas line cap would work I just need to know the correct plug and thread size. Thank you.

    I took my header into the hardware store and was able to find something to work but can't remember what it was now.

    I'm definitely not taking off the manifold to take it into the hardware store. I saw a post somewhere that said 5/8s but I don't know if they were talking about a 5.0 or 4.6 motor. If nobody knows for sure I'll just buy a few that look close and hopefully get one that works

    4.6l uses a 5/8 brass cap to plug the egr port. Its not perfect thread but its soft enough and close enough that when you tighten it down it makes its own threads and seals up. Im not sure about the 5.0l. Do you need a plug or a cap?

    I don't know, I just need something to plug the hole up so it's not just aluminum foil stuffed in there leaking exhaust gasses everywhere. Seems like a brass plug would do the job. Whoever had this car before me did a bunch of dumb half ass shit to it.

    I'm planning on getting long tube headers in the near future so this just has to be a temporary fix. It doesn't need to be perfect just better than foil.

    I don't remember - do the manifolds have a male or female threaded boss? I'm assuming female since you're saying "plug."

    Or you could weld it shut like I did on mine.

    I completely forgot that's what I ended up doing on my old set.

    Find a used tube in a junk yard and cut the pipe, remove the nut, put a penny in it and screw in on the manifold!
