Just a thought, I really don't want to take my manifold off to drill and tap it. sooo can it be put on the EGR delete up pipe? Or will it not be effective?

you dont have to take it off.. i tapped mine on the bottom of it from under my truck and it works just fine

no need to take it off just put grease on the drill bit and grease on the tap as well that will get most of it then take a magnet and fish in the hole until it comes out clean!

Hahah no, I dont want to do it that way.

haha i would do it the way i said.. the readings seem to be fine from putting it there

I did it that way, except instead of the grease on the drill trick (which I didn't think would work all that well, since the bit heats up and melts the grease), I (drumroll please) had someone start the truck before I broke through with the bit. The exhaust pressure will blow all the shavings out and they won't go through the turbo. After I broke through, shut it down.
Start the tap, and just before you are all the way through, do it again. Don't be "that guy" that tries this without protecting yourself.....

Drilling the manifold while installed is fine. There's been thousands of people do it that way, and I have never heard of an issue caused from it.

This is how I, and many others, did it.

Yea just do what NYC 350 said to do. That is basically what I did and I have had no problems for the 20K miles so far since I did it.

I did mine exactly like the picture. I did NOT have the engine running and I did NOT grease the drill bit or the tap. It's my understanding that the flutes in both are designed to clean the bit and the tap while it's working and plus you will have gravity working on your side. It's a very simple job and plenty of room to drill and tap the driver's side manifold. I also used my shop vac to suck out anything else that might have been left in the manifold after I drilled and tapped it.

Now you've heard success stories from mulitple different ways to do this. Take your pick.

Did it on my 7.3 the same way, no problems.
