I just acquired an ls1 intake for my 5.3. When I cleaned it, I noticed that when I look down the TB opening I can see light coming through the three holes in the bottom of the intake. I'm assuming that shouldn't happen as the intake should be sealed from the outside. It looks like I could easily plug the holes. Can someone tell me what these holes are for and confirm they should not be open to the atmosphere. Thanks

Yeah, these are the holes that are molded into the intake. They are on the bottom side. I have looked at other intakes online and they all have the same three holes. They are the opening to long vertical tubes but a have a small gap between the base and the vertical tube. Seems they should not have the gap otherwise air will enter without going through the MAF sensor. Definitely not NOS.

Here is a pic of the holes I am talking about. Mine is like the intake on the left.

those holes are part of the columns that are in the intake.............there should be no open "holes" in the bottom of the intake that can create vacuum leaks

Thats what I thought. It looks as if the columns separated from the bottom. The gaps are very small so I think I can easily seal them up with some epoxy or resin. Thanks for the info.

Good thing you found that now or it would have driven you nuts later on down the road.

Yeah, I'd have been searching for the vacuum leaks forever!

BTW, 3M makes some great plastic bond epoxy stuff. It comes in a double tube syringe type deal and you need to mix it. It works great, you should try it.

Thanks for the info. I'll give it a shot.
