EGR Pipe Cap on Manifold

[ladddn]

I know this has somewhat been discussed on here, but nothing I have read have had the answer I need, everything focuses on reprogramming and intake plugging.

My question is, outside of welding the hole up, does any know what thread and size the tube coming from the manifold is, or where one can buy a cap?

I recently built a 383 stroker and installed Gibson GP102 headers and my factory tube will not full tighten so I suspect this weekend when I fire it up for the first time it will be a nasty exh leak.

I know I will need to reprogram the PCM to turn off the CEL and I know I will need to plug the intake if I remove the egr valve itself. Just to be clear, my question is regarding the pipe on the header/manifold.

And bending the pipe over etc will not work because the seal is loose.

I am also trying not to have to pull the header, as I just installed it, nor do I want to weld on brand new headers. So a "in the truck" fix is ideal.

Thanks for any suggestions and help.

man i never remember the sizes of those holes. perhaps the egr can com off completely to take to a hardware store to match the size.in fact is there high temp pipe dope that may seal a potential leak maybe. have you consulted with header make about it being an issue with header or is it for sure a line issue? i would rather try bumping the header a bit to get it sealed then go thru all that mess of modding and reprogramming myself.

If I can not find a pipe cap at the hardware store plans are to simply place a pieve of steel like a washer on the inside to create a seal and weld up the center top where the pipe went through... creating my own cap.

Gibson does not provide a cap because they are Carb compliant...
