kev Posted August 18, 2015 Report Share Posted August 18, 2015 What is the general opinion on what to do with the erg port in the head when going mpi? Are most people just using the normal intake manifold gasket and blocking the hole by the intake flange? I thought I remember a post from years back showing the hole in the head tapped and a threaded plug installed. I'm assuming this was on the intake side of the head.

importwarrior Posted August 18, 2015 Report Share Posted August 18, 2015 the EGR port on mine was blocked off with the mookeeh block off plate on the magna MPI manifold. http://www.ebay.com/itm/STARION-EGR-BLOCK-OFF-PLATE-CONQUEST-/380228308053?vxp=mtr&hash=item58875f8c55 Link to comment Share on other sites More sharing options...
kev Posted August 18, 2015 Author Report Share Posted August 18, 2015 My magna manifold doesn't have egr provisions. The flange simply covers the hole on the head. I'm just concerned about the exhaust killing the intake gasket over time. Plugging the passageway may be the right way to go but it comes out of the head in an angle making tapping the hole more difficult. I have fears that I'm going to screw up the head. I guess I should have thought, or remembered, about this before having the head ported, etc. Link to comment Share on other sites More sharing options...
scott87star Posted August 18, 2015 Report Share Posted August 18, 2015 One of the old PQ posts shows him driving a small Dorman plug into the port on the intake side of the head. Link to comment Share on other sites More sharing options...
BuGG Posted August 18, 2015 Report Share Posted August 18, 2015 (edited) One of the old PQ posts shows him driving a small Dorman plug into the port on the intake side of the head. This. He put two 1/2 freeze plugs with high temp silicone behind it and also showed it getting drilled and tapped.

Potamus Posted August 18, 2015 Report Share Posted August 18, 2015 I drilled and taped the hole in the head on the intake side and installed an allen screw in plug. Link to comment Share on other sites More sharing options...
kev Posted August 18, 2015 Author Report Share Posted August 18, 2015 Did you drill and tap perpendicular with the flange or did you follow the port angle? Kevin Link to comment Share on other sites More sharing options...

kev Posted August 19, 2015 Author Report Share Posted August 19, 2015 Thanks guys! I found the old PQ post...pics are gone but it is self explanatory. It addressed my concern. I think I will counterbore it at 1/2" like he said and then drill 7/16" for a 1/4" NPT plug. Phil, How the heck did you access that hole on the exhaust side?

Funky Phil Posted August 19, 2015 Report Share Posted August 19, 2015 (edited) very carefully hahaha. I found a plug that was barely too big, put sealant on it, and wound it in there tight. Edited August 19, 2015 by Funky Phil Link to comment Share on other sites More sharing options...
kev Posted September 14, 2015 Author Report Share Posted September 14, 2015 Closing the loop on this thread. Here is what I did: Couldn't locate a 1/2" NPT plug efficiently, so I used a 1/2-20 threaded plug. I drilled the port with the proper size tap thread for 1/2-20UNF following the port angle. Cleaned everything really good. Then I used high temp RTV and installed the plug...with a little 'umph' once it reached the last tapped thread to help hold it in there. I threaded it a little farther than I should have. I wanted the plug a little closer to the intake flange but oh well. http://www.hotrodders.com/gallery/data/4394/medium/DSC026511.JPG http://www.hotrodders.com/gallery/data/4394/medium/DSC02649.JPG kev Link to comment Share on other sites More sharing options...
