JB Weld to re-attach Vacuum Hose to Intake Manifold?

[FordGuy1990]

I was replacing an old PCV hose on my 2000 Taurus 3.0L 24V DOHC, and when i was trying to take off the spring clamp, the pliers slipped off and slammed into a plastic nipple connecting a vacuum line to the bottom of the intake manifold. I was wondering if I could use JB Weld to re attach this hose back to the Intake Manifold.
I took the car into the local Ford dealership and they quoted me at $824 to replace the upper intake manifold to fix this and I cannot afford that right now. Any help would be greatly appreciated!

Yes, you could use JB weld, but it's going to be a liability. If you glue it, you have to make sure it doesn't leak at all when you're done. You also have to worry about it breaking again when you reattach the hose. If it breaks off later you're going to have a big vacuum leak and the engine is going to run bad.

If it were me, I would just go to a junkyard and pull an intake manifold off another 2000 DOHC. You can replace the intake gaskets while you're at it. If you want to do a good glue job you should take the intake manifold off anyway, so why not just replace it?

Okay, I appreciate that! I never thought about a junkyard! And just to be clear, before I do this, the upper intake manifold is all connected (one big plastic piece) and connects to the throttle body, correct?
Also, the small rubber hose that connects to the plastic nipple on the bottom of the intake manifold (closest to throttle body) will also need changed since the other half of the broken nipple is stuck in there. Do you by chance, know the size of that hose?

The hose should have 1/4, 5/16, 3/8 marked on the line with white writing if you look close. The other way would be to use a tape measure to estimate the diameter. I have no clue which hose you are referring to but most are the sizes I listed. Good luck. It is an easy swap if you get a manual and become familiar with the parts and order of removal and replacement.

If the hose is still flexible and pliant (in other words, not dried out and cracked) there's an easy way to salvage it. Squeeze the end with the broken plastic nipple with a pair of pliers. Not ViseGrips, not ChannelLocks, just hand pliers. The plastic broken in the hose usually is so brittle, it will crack into smaller pieces at which time you can blow it out, or simply rap the hose against your workbench and the broken pieces will fall right out. Repeat if necessary until the hose is clear of debris. If the broken piece doesn't cooperate, a pair of tweezers or needle-nose pliers works too after crushing it with the pliers.

Another option with your current manifold. Remove it, drill the broken nipple / hole to a little larger size, tap it for a brass NPT thread to barb fitting available at any hardware store, and screw in the brass fitting. Adapt the hose to the barb fitting. You can put JB Weld on the threads for extra strength. Of course, replace the gaskets. Even if they dont leak now, they eventually will assuming they are original.

Thanks for all the feedback, guys. I think I'm just gonna go ahead and order the manifold and 6 gaskets and replace it all myself. No need to pay close to $400 for labor for such an easy job. Since the car still runs (it's a little shaky) and I can do the short trips I need with it, there's no need to try and rig it. Thanks again, everyone!
