Inatake repair
Hi Guys,
I just received my LS6 intake that I purchased from a member on here. It was shipped UPS and packaging was a little iffy. Anyways when I opened it everything looks great except I noticed a plastic nipple laying in the box. It is the Nipple for the PCV vacuum hose that is right behind the throttle body on the passenger side of the intake. How do I repair this? The nipple fits right back in there perfectly but what is the best method to keep it there and prevent any leaks or it breaking off again? Heres my ideas:
-Use a plastic epoxy (like the dual tube one at wal-mart) and goober it up good... maybe jb weld? Suggestions?
or
-Clean the excess broken material out of the hole and install a threaded brass nipple in there? My thoughts about this though is there is only about 1/8-3/32 worth of plastic for the nipple to actually thread into and then another concern was if the brass threads protrude into the intake somewhat and it interfering with some of the intake air flow (im going for max power here) and another concern was getting the threads to seal and no leaks inbetween the threads which could be fixed with a rtv sealant id imagine.
Thought or anyone have a success story??

That was my second idea as you can see above. But my only downfalls that I see with that could be that it does not have much plastic to thread into and second if some of the threads protrude into the flow of the mouth of the intake of the intake will it disrupt airflow and maybe mess with my power gains??

Yeah...I'd do a new threaded insert and seal it with silicon or epoxy. If your concered about appearence. I'd sand the intake, then insert/epoxy...sand gently around the fixed area...then paint new (duplicolor). It never happened.

I am going the brass route. Only found the right combo in a pipe thread so I just have to get a pipe tap to tap the hole. I will post results when I finish.

Its finished, Got a 3/8" pipe thread barbed fitting. Tapped the hole, put some black RTV sealant on the threads thick and threaded it in as far as I could by hand and put the wrench on it and turned it another half of a turn. It protrudes into the intake throat by a fingernail width (about 1 thread) so I feel that it wont interfere with any air flow or such... unless someone disagrees then I will back it out and re seal but it felt good and tight and leak free going that tight. Everyone think that it will be leak free with the steps that I took?

60grit...100 grit...220 grit...400....800..2000 grit sand paper in that order.. I probably overdid it, but I've never painted anything before so I wanted to make sure it was super smooth. Essentially you could go 60,220,600,1000, and be done with it.
2 light coats of duplicolor primer...3 or 5 coats of the paint (whenever your happy with color) and about 5-7 coats of clearcoat. Cost about 35$ and took about 2 days because of drying time of the paint..super easy and turned out better than expected..looks like it was done professionally
