You can, but you’ll need to use caution.

In fact, you may use duct tape to repair small rips or leaks in your car’s exhaust manifold.

When you have an exhaust leak, you’ll want to make sure you do it right and get the best possible results. Here are some tips you should keep in mind:

Your work area should be cleaned. You’ll have a beautiful, flat surface for your patch if you do this. You don’t want any more debris causing issues later since you’ll probably be using duct tape (or foil tape).

  • Find the hole or crack you want to fix using soapy water. You may have to use a flashlight to view it, but you don’t want your duct-taping project to develop into a guessing game where you tape over everything you see!
  • Tools you’ll need include sandpaper and used rags which you don’t mind discarding.
  • To soften the area you’re fixing and make your work easier, you should apply heat to it. You can do this with a blow dryer or other tool, but you must take extra caution to avoid burning yourself!
  • You’ll need to reapply heat once the hole or leak has been fixed to make sure the area is completely sealed. Only a blow dryer should be used for this.
  • You may now tape duct tape around your exhaust pipes. To achieve the greatest results, wrap it tightly. You might even want to use two pieces of tape for increased security.
  • If you were able to locate the hole in the first place, you should also inspect your exhaust manifold for leaks after you’ve completed this. To ensure that there are no more issues, you should perform this with the car in gear and running.
