Standard Procedure - Intake Manifold Vacuum Port Repair
WARNING: This page is about a different variant/trim than selected.
The composite intake manifold vacuum ports can be repaired. Although, if the manifold plenum chamber is damaged or cracked, the manifold must be replaced.
To repair a broken or damaged vacuum nipple (port) on the composite intake manifold, perform the following procedure:
| PARTS REQUIRED | TOOLS REQUIRED |
|---|---|
| Brass Nipple - 3/8" O.D. x 1/4" pipe thread (Speed Control Port) | Pipe Tap - 1/4" - 18 NPT |
| Brass Nipple - 1/2" O.D. x 1/4" pipe thread (Brake Booster Port) | Drill Bit - 7/16" |
| File/Sand Paper |
NOTE:
While performing this procedure, avoid getting the manifold material residue into the plenum chamber.
- File or sand the remaining port back until a flat surface is obtained (plane normal to nipple (port) axis).
- Drill out the nipple port (2) base using a 7/16" drill bit.
- Using a 1/4"-18 NPT pipe tap (1), cut internal threads. Use caution to start tap in a axis same as original nipple.
- Apply Mopar® Thread Sealant to threads of repair nipple(s).
- Install repair nipple(s). Do not over torque repair nipple(s).
