I was watching the Horsepower TV Marathon today on Spike TV, and they put a performance manifold on I believe it was a chevelle. Anyway, they used gasket sealant on the new manifold, and even went so far as to recommend ALWAYS putting the gasket sealant when putting on ANY aftermarket manifold. So, for anyone worried about the quality of the Kinetix plenum strictly due to worrying about having to use sealant, DONT BE. I've attached an image of the exact sealant they used, which happens to be the same kind I used...

PS... I'm LOVING my plenum, the growl is terrific. Just today I started my car up while two hotties were walking by. They stared for a good 15 seconds as they walked away...

 

doh, forgot the picture...

 

RTV is not impervious to gasoline. I would recommend something else to seal an area that may come into contact with fuel.

Just a thought.

 

Are the fuel injectors not below even the bottom manifold?

PS; I would probably have used this had I got the crawford piece as well, just to make sure.

 

Fuel can get into the upper plenum. Plus some people run a nitrous wet shot which shoots fuel right in there. It does not matter what plenum you use. As for using it with ours, we send a new gasket with it. You can double up if you want to (or need to), use the new one only, or save it for later. Our official recommendation would be if the Crawford plenum does not seat due to severe warpage or shipping, send it back and it will be taken care of . . . do not use RTV to seal the plenum. I think lsdunique will agree the goal is to get it to seal without then mess, hassle, and provisional solution of RTV. If it is not sealing I think he is taking them back, that’s what I have heard from some of the people with them.

Good luck.

 

Yes, he didn't give it a second thought and sent me another one ASAP, great service and not issues so far with the second one.

 

Like the imposter, I was shipped another plenum. V2 to be exact. Works like a charm, but I did strip the threads on the long bolt near the throttle body. Popped them out of place. I need to try a bigger bolt I guess. It doesn't leak without it in place so I'll just go with it for now. Maybe use a little sealant. Damn I hate aluminum.

 

I stripped that bolt too. Go buy a 75mm M6 bolt and all will be well. I suggest using 1 or 2 washers since the plenum in that area makes it hard to torque it down to to contact with the wrench.

 

If you run out of options you may be able to Helicoil the hole. Not sure how available a metric Helicoil kit is, but it could be worth a shot if nothing else works.

-D'oh!

 

Try breaking a throttle body bolt that will make your day all cheery, my idiot ex friend did on version 1 , special order part too and it''s a leak till the 2 dollar bolt comes in.

 

I don't think Kinetix version 2 need the rtv, since you can tighten it down a lot more than version 1. But I was using rtv when I installed version 1, and after taking the plenum off, the rtv did not stick to the bottom paper gasket. Nothing to scrap off, very clean...

 

Yeah, don't use the Permatex Black. Get the Ultra-copper instead. It's better suited for the Plenum application. It's what I used anyway .

Hmmmmmmm

 

Hmmmmmmm is right! That's really weird. Why would Ultra-Copper be "the best" thing for pertty much everything on an american Made car, yet not be good for anything on an import??

That's bizarre!! BIZARRE I SAY!

Well, I used Ultra-Copper and I'm damned proud of it! I'd use it again if I had to! Yeah! I regret nothing... nothing at all! (at least it says it's good for import car's intake manifolds) Hehehe!
