EGR Port Cleaning

[JohnD1079]

ok, Before you guys tell me to search, or link me the 2 DIYs + a bunch of reading on it, I have a couple questions.

My Intake Manifold Dosent Have the exact circles that I see most of you guys have. (It round at the top not flat). So i just drill in the middle of the hole? Does it just crack around the the plug or what? I read that you could shave those "welds" off and you will see an outline or brass plugs, is this true?

Where exactly are the plugs? Just on top? and you drill them out, or what? I want to put in those allen type bolts in as plugs, so i can remove and clean easier later with no drilling or anything like that. Like what are they called(so i can ask for them at lowes, home depot etc...)

Also WTF is a punch? I search "punch tool" on google, and i have never seen any tools that came up

What Sealant is used? and where? On the threads of the plug or on top? You mean like JB Weld type sealant or a anti-seeze type sealant? You dont JB weld up the top of the plug do you?

This is for a H22 intake manny. I think for the a1/4/6 there is the flat part with the visible circle. But for the H seres the isnt. How exactly do you

Knock the plugs out of the hole. what i found easiest instead of drilling them out and using a slide hammer was just knocking them all the way into the hole with hammer and punch.

Im just soo unbelievably but yet i want to do this the right and smart way.

This is what i am talking about with the outline of the plugs not visible. (Mine essentially looks like that, someone elses pic)

A punch is just a metal rod with a tip at the in, you use it with a hammer so that you make a little dip in the metal and then break out drill so you have a good place to start.

And people buy a "tool" like that? Cant you just use a nail?

Anything on the cleaning?

[jhondayaaj]

I don't think you can do it on that manifold.

[JohnD1079]

You mean you cannot weld up the top, or you cannot do a EGR Port cleaning on them.

This is what mine essentially looks like.

It looks kinda like someone cleaned the ports out one day and just laid on some jb-weld or something like that on top of the hole but i think u can still drill it out and clean out the ports, just not sure whats a good way to seal them up.

Sure you can drill and tap those holes......here's my H23 IM:

Start with 1/4" Bit in as close to the center as you possibly can......slowly step up to 29/64"

Then go buy a 1/2" NPT tap, tap the holes carefully (it is a little tough to get it started with the uneven faces...

Purchase these plugs and you're set:

And since both the manifold and plug are aluminum, they should have roughly the same expansion rate, so a little blue thread lock and you're set

As mentioned drill it, tap it, and replace it with a bolt.

H manifolds always look like that. I think they came that way from the factory. But you can still do it, like that guy ^

A punch is a spring loaded hole marker. Dont use a hammer, you'll hurt yourself...

You use it to mark a spot in metal to begin drilling. Basically, youll press it down until the spring inside pops. At that point, it will feel asif the spring broke, but it actually releases its pressure, causing you to slam into the top of the metal rod protruding from the punch, which in turn creates a tiny dip in the metal you were pushing on.

Its a great tool, highly recommended. However, If you only need it for this, just use the hammer and nail I suppose.

If you but thread locker, how do you get them out next time?

threadlock comes in various strengths, denoted by the color. some only provide a little bit of stick to hold the bolt in, while the harder ones make it hard to remove... get the medium, it seals and holds it, but is removable/reusable.

i <3 the glues and sealers rack at autozone. lot of cool variations on stuff like this, i like to pick out random ones to try out lmao

Blue thread lock is medium strength

That's a *centre punch*....not a punch.
