smog pump delete

[clang5oh]

what did you guys do with the tube that comes out from the back of the heads.

throw in the scrap bin. Plug two holes in back of heads. These holes are standard thread can't remember the exact size i think 7/16. Not pipe thread------a common misconception

just flip the pipe and block the holes off.

I used 2 bolt too .. I think 7/16 is about right

but ford do sale them I dont remember the part number if you do a search you'll probably found it ...

just flip the pipe and block the holes off.

That works too but, weight is weight not to mention it clears up the engine bay and makes the top bellhousing bolts easier to get to from the top if you are pulling the trans for some reason.

Yes ford does have the plugs. I don't know the part #.

i got the plugs form a machine shop.. lik 5 bucks a pop though ouch

The plugs from ford are $15-$18 dollars each. Price varies from dealer to dealer for some reason. You can use a bolt and washer (5/8 x1" I believe) to plug the hole if you want to remove the pipe altogether, or the easy option if you just want the pump itself gone is to use a short (like 2") pipe coupling and a pipe plug to just close up the end of the pipe above the header.

If you are going to delete the smog pump then you will need a threaded insert known as a thermactor plug. They screw into the back and front of your heads. Put silicone on the threads to prevent any exhaust leak when installing them. The thermactor plugs you will use for the front (same as back) will go to make the head holes smaller so the accessories can bolt up like your power steering stud and one of your bigger alternator bolts that go through you alternator bracket. The back thermactor plugs you will use just block off and delete the smog equipment’s previous hookups. You can get them at a Ford Dealership - part # F4ZZ-6E086-A or you can buy some from Summitracing - part # TFS-51400265 and they run anywhere from $3 to $12 dollars from what I have seen. Summit has them cheaper for around $4 bucks I think. I got mine for free (local hook-up)

I like the deleted pipe back there but it will work if you flip it (was originally done on mine)...it only weighs a couple pounds but the extra clear(ance) that it gave was worth more than the weight of it to me.

I cut the ends off the pipe and just bolted those back on, but back to front. It makes sense when you can see it. One side has a hole and the other is flat. Turn it round so the flat part covers the hole in the head.
