3tc EGR question

Post by superdevil »

Hey guys, long time lurker, first time poster. I just picked up a 5 finger intake or my 3tc. I've already deleted the EGR valve and I just deleted the other valve under the intake(the valve the smog tubes run too). My question is since I have a egr head do I need to plug the egr port on the intake side? The port right behind the dizzy, I can take a pic if anyone needs further explanation.

Block off the EGR with one of these then your all good, no need to do anything else. I bought 3 of em, really worth the price.

That port is just a bypass from the EGR to the intake nothing else if you plug your egr from the #1 exhaust port with a set screw you can run a non egr T-stat housing and forget about the rest, you also can cut/trim an EGR t-stat housing to look like a Non EGR t-stat housing, i done many they look much better!

So really I should just pull the header off and remove the smog tubes all together? Then if I want cut the EGR t-stat housing?

No, you have to plug the smog ports, they go directly to the exhaust port. From #1 there is another hole to the EGR you must plug to run the EGR delete water neck housing.

Ok I think I see what you mean. When I pull the housing off the port on the far right?

BRD sells the smog plugs but he only carries one size and insist that they are all the same. I know for sure there are 3 different sizes of smog port plugs. I have never found any of these size plugs in my local hardware stores. If you dont have a welder, you can cut the tubes long, flatten with a hammer and roll up like a empty toothpaste tube. If you have a welder you can fill the holes and put them back in.

I took some pics so you can see how the head passages are for the EGR. I put white tie wraps to show how they run. I also took a pic of the early head so you can see the difference, they have threaded ports but are not drilled through like later heads.

Water neck housing above head.

#2 through #4. sometimes #1 is not drilled all the way through and doesnt need a plug.

Early heads not drilled trough, no plugs needed.

No problem, just for overkill, couple more pics.

Smog plugs, one welded and one rolled.
