i have asked about this before and have not recieved a real answer.what is the best way to cut out the perforations for the egr valve on a intake manifold gasket? i can't be the only person to use the option of keeping the egr valve functionable.also what is the best intake gasket to use if you are keeping egr.1987 chevy 5.7L/350,in a caprice with carb.thanks,joe.

Hmmmmm, most egr's that I have seen don't come near the intake manifold. Plug into valve cover then go to carb via vacuum line. What am I missing?

[hemi joe]

egr valve is directly on intake manifold for a chevy,maybe your thinking of a foriegn car???????????//

I think the Rookin daddy is thinking about a pcv valve in the valve covers, my egr is on the passenger side of the carb. in the intake.

You talking about the crossover? Regardless, if you need to cut an intake gasket, a manual (as in hit w/a hammer) hollow hole punch will do a good job.

Back the gasket w/a block of wood for support, scribe the lines you need to follow and have at it.

If you have wood working tools, a small wood chisel can also be used to cut out the hole and might be easier than a hole punch- depending on the shape you need. Back the gasket w/wood, same as above.

Good luck.

i just don't get it,if this is a factory replacement why is the cutout not there.maybe i'am missing something???if i want to buy a replacement gasket why are the cutouts not already there.every chevy made has to have the same gaskets for that year and on.egr is a factory part.sorry i don't understand why you would have to make a gasket work....

You are correct. I think you are getting the wrong gaskets.

i can't believe i'am the only person to have this problem. i'am not talking about the heat crossover.i'am talking about the cutout for egr.the performation is in the gasket for cutout but there is steel in the gasket ,why don't they sell a gasket pre-cut for egr.

Ahh, long day. I was thinking of PCV. DOH!!!!

Old millwrights trick to cut the gasket is to use a ball peen hammer, using the ball end peen the gasket against the sharp edge of the manifold opening and slowly work your way around to cut it out. Takes some practice but it works like a charm, especially on metal reinforced gaskets. Give it a try, make sure you peening the edge of the opening and hold the gasket in place securely while doing it. Some bolts through the gasket to locate and some big washers to clamp it tight works well.

One last try at this.

The EGR gets the gasses from the heat crossover. Not from anywhere else. The holes you see in the intake manifold flange are supposed to be blocked off by the gasket- that is why your gaskets do not have those holes in them, and why you will never find a gasket that does have those holes open. The heads do not have any holes for the intake holes to connect to- DO NOT open the holes up on the intake gasket!!!

Just assemble the gasket the way you would normally and ignore the holes in the intake flange.

The heat crossover has to be open through the gasket for the EGR to operate correctly- do not block the crossover holes in the intake gasket!

thanks colbalt,i think i got it now sorry for the confusion.
