I have an SLP / LS6 intake that has a big hole in the back, and the spigot is loose. Since SLP stopped selling these I'd like to repair it and put it on my car. Has anybody ever tried repairing a manifold before. I wonder why SLP stopped selling these

Plastic weld and JBweld to fill in the tiny cracks

How did the hole get there? Improper handling or nitrous backfire?

Mine was sightly loose too, so I pulled the nipple out and put some Ultra Black permatex around it. Or I left it in I cant remember.

I bought it on Ebay. It was delivered damaged. Seller didn't pad the back very well and the box looked like it was dropped on it's end. And no he didn't insure it as he said he would. I learned a valuable lesson about insured packages.

JB Weld. Try a search for repair ls6 intake and there should be a few threads.
Here is on of the better ones:

I had almost the same damage on an LS6 intake and I used 4 coats of JB Weld to patch the hole.

Here is the damage prior to repair

It's nylon 66. If it were me, I'd go get a black spatula from Wal-Mart
and a spade tip soldering iron and go to town on it (plastic welding,
shade tree style). Black plastic spatulas being the same material
minus the filler.

Can some tell me how to get the spigot / fitting off the back of the manifold so that I can reach in behind the hole to make a block.

I'd like to try the welding method but I'm told that spatulas have a Teflon coating on them and it won't adhere. I also can't find nylon 66 welding rods. I went as far as looking for someone that welds plastic, no luck around here

There's no coating as far as I can tell. Certainly if there
was, they'd be proud to tell you and charge extra.

LOL. You make a good point. I'll check it out. Next is to find nylon 66 weld rods

There are three tabs at about 2:00, 6:00 and 10:00 on the back of the fitting. If you manage somehow manage to depress a couple of these, it should come out. A lot of talk about doing this, but I don't think anybody has been able to remove it without damage. Mine intake was damaged enough that the original fitting could be removed. I lost it over the years that it sat on a shelf and had to replace it with one from my old ls1 intake. I ended up having to cut the old intake to get the fitting out.

Having that fitting out made the repair much easier. It allowed me put a backing in place before the first coat of JB weld and filled back even with the inside edges.

BTW: When I was explaining this intake to an old school guy (he was dumbfounded when I mentioned a plastic intake) at work he mentioned that he had used cable ties and a soldering iron in the past to make plastic repairs. I just went with the JB Weld method as I had a large gap to fill as well as the cracks.

Aviation type epoxy. Dries rock hard and wont crack. JB weld will eventually pull away from the nylon. The aviation epoxy will melt itself into the nylon for a chemically induced primer effect.

i woulda thought any decent sized body shop would have those plastic welding rods,doesnt anyone do the bumper reair/welding anymore?used to be a guy outside of town here that had sign saying plastic bumper welding,thats all he did...

Thanks for all the advise everybody
I couldn't find anybody around here that did plastic welcing so I stopped feeling sorry for myself, got off my butt and and repaired the manifold. I got a piece of the same material and welded a patch over the holes, using a soldering iron, and then applied JB weld. It's not West Coast Customs quality, but it'll do
