Plenum Help!!!
I'm trying to install a polished plenum but the two vacuum tubes were bent. The L shaped one I tried to pull back but when I did it broke the tube at the bend. The smaller one, I don't even want to touch.
So what's the best possible way to fix this? It was suggested that I remove the tubes from my old plenum but I don't think that's even possible. Do you all think I can use JB WELD on it or will it be too hot under there? It says it can withstand up to 500 degress? I hope I can fix this because I paid a little more than usual since I had to get it shipped to Hawaii. PLEASE HELP!!!




Often times those fittings are not intended to be removed/reinstalled. However if you can get the ones off your OEM ones without breaking them you can try reinstalling those on the new plenum using something like JB Weld or other adhesive.
Personally I wouldnt try "repairing" the broken ones. If anything just try to put the OEM ones in.

You could use one of our Copper Iso Thermal upgrades in place of the tubes on your plenum.
It will also allow your plenum assembly to run a lot cooler while still keeping your TB heated.

So this will install to the vacuum hoses in place of the vacuum tubes??? Please explain.

Btw, i already have those upgrades.
thoes arent vacuum hoses in the picture, they are coolant flow tubes. The copper iso thermal is a bypass for thoes tubes.
And the good news is if you already have the upgrade, you don't have any problem... You won't be hooking up thoes broken tubes anyways. And they won't be leaking any vacuum because they don't pass into the plenum vacuum area.
Problem solved.

SWEET!! So the hoses that are hooked up to these tubes are basically obsolete?

Oh.... You don't have the Copper Iso Thermal....
What you have in the picture above is the regular Iso Thermal. Thats very different.
Now you need to get the "Copper" Iso Thermal upgrade.
Back to square one.

Alright, if I get the Copper Iso Thermal upgrade this will by pass the broken tubes on the plenum then?
I guess this is my only option at this point, please advise.

+1 on those being coolant valves/tubes.

**BUYERS OF POLISHED PLENUMS BEWARE, MAKE SURE THAT WHEN ORDERING THESE PLENUMS FROM ANYONE, VERIFY THAT THESE TUBES ARE NOT BENT IN ANY WAY.**
I had to learn it the hard way.

I'm trying to get it worked out with the seller right now. It wasn't the shipping because the box that it came in was fitted just enough for the plenum to go in with the bent tubes. After I bent the large tube back the way it's suppose to, I can't get it back in the box. Plus the way it was wraped leads me to believe it was already bent when it was placed in the box. Can't return because I'm in HI so I would loose a whole lot more money. I just hope that this person will do what's right.
