Is this the right area to weld on the intake for EGR blockage?

[Black Knight]

I finally got the intake off and am 99% sure I know what to do then I second guessed myself and figured I would ask before I screw up my intake. I've read threads on how to block the EGR passage by putting a ball bearing in there but I didn't want to do that. Besides if I weld up the intake where it meets the head instead of sticking a bearing in it where the upper and lower meet wouldn't that be better anyway? Exhaust gas would be just that much farther out of the intake manifold?

Here is the passage we want to block on top of the lower intake manifold

Here is the bottom side of the manifold where the exhaust would come through at

A closer pic of the same hole, its actually a rectangular slot on the right side of the dark area

Now this I don't understand, it appears to be a spot where exhaust hits the manifold but there is no passage for it to go anywhere. Like it should have a hole to go up but doesn't.

This is the spot on the pass. side of the motor where the EGR is fed from the head.

And on the opposite side the same hole but again it goes nowhere on the manifold

So basically will I be OK if I weld up that retangular slot in the manifold?

Weld up the square hole youre pointing to and youll be good.

Your thinking is correct in that blocking the exh gasses further away from the manifold is better and if you feel like putting forth the effort to block the passages off in the heads its an even better deal. The closer to the exh port in the head you actually construct the blockage the less heat gets put into the intake manifold but if you have to block it at the intake rather than inside the head then blocking it where the intake meets the head (square hole youre pointing to) is about as good as you can get.

You got any ideas on a way to block it off in the head? I think if I end up getting that involved with it I would be better off just switching to vortech's ( I think they were the one's that didn't have a EGR passage at all ) You know that slot in the intake will be easy to weld because of size, but what to do on the heads? They do give you those metal plates with the intake gasket setups sometimes I wonder if I could put those on top of the hole?

Yes the metal plates are fine or you can make some of your own out of shim stock etc.

I got creative (IMO ) and cut out some block off plates from 16 gauge 304SS that fit the exh passage and then poured some molten mild steel into the exh passage behind the block off plates to hold them in place. Prolly a LOT more effort than it was worth but it made my pants happy.

Using the block offs that come in intake gasket kits would prolly work too...I didnt think of it at the time even though Ive got a dozen or so of them laying around :roll: .

:rotf: The way you worded that just made me laugh so hard, all I picture you doing is taking your heads to big steel mill (like in T2) and trying to stand under one of the buckets as you poor some molten mild steel in there. :rotf: Your freaking crazy, but I like the way you think :tup:

A redneck with a set of torches and a pile of scrap steel is a dangerous thing.....or a wonderful thing depending on how you look at it :lol:

You'd be hard pressed to weld in your head. I'd block off the intake manifold. JB Weld will hold up to the temperatures seen in your intake as long as you use coolant.

switch to vortecs and forget about it.
