Recently, a rumble in the engine alerted me to the fact that my exhaust needed attention. Sitting in my workshop, I was wondering whether I could salvage some cash and repair the exhaust pipe myself. I did some enquiry, and this is what I came up with.

While all-encompassing damage to your exhaust arrangement means a trip to the garage, information technology's adequately piece of cake to bargain with small leaks yourself. Here are 4 DIY methods on how to repair the frazzle pipage.

But condom kickoff: before y'all start, make sure your car is raised up safely, that the exhaust arrangement has cooled down, and that you're wearing the appropriate safety gear.

Mutual methods to repair an exhaust pipe:

Repairing exhaust holes with a welding machine

This method is the i I'd recommend, because it is a reliable and safe repair. Of course, welding an exhaust pipe requires some expertise with welding equipment.

In many cases it is easier and cheaper to cut off a part of the exhaust pipage and accept a new part fixed instead of replacing the complete exhaust system. For smaller holes you could try to weld a patch.

Very likely, y'all will need to detach the frazzle from the motorcar in society to weld it.

Concerning equipment, you lot will need:

A slice of frazzle tubing
A pipe cutter or hacksaw
A grinder
C-clamps
A welder
Safety vesture

Safety get-go: Be sure to clothing your eye goggles and welding gloves while using welding equipment and be aware of any flammable materials in the area.

The first stride is the most important one, every bit the exhaust tubing needs to be cut neatly and accurately. Measure and mark carefully before cut with the pipe cutter or hacksaw. Work slowly and carefully as the cut needs to exist as straight as you can make it then everything volition finally fit seamlessly together.

Clench the exhaust tubing together using the C-clamps. Brand sure they are exactly how you want them earlier you begin welding.

Go around the circumference of the tubing, applying iii or four spot welds. This prevents the tubing from warping and losing its shape.

At present, apply the welder to make full in the gaps, continuing over the spot welds you accept already made. Make certain you have a 100% weld right around the tubing to prevent farther leaks from developing.

Requite yourself a pat on the back. You should be proud of fixing the exhaust yourself and saving yourself some bucks. Be aware, though, that home fixes are non permanent, only buying y'all time and may not be enough to get your vehicle through its next safe inspection.

This method is only suitable for small holes. Large holes need a patch.

Y'all will need:

a steel brush
fine sandpaper
acetone (or blast varnish remover)
expoxy
exhaust record

Scrub the area effectually the hole thoroughly with the steel brush to remove dirt and rust.

Then get over the surface area again with the fine sandpaper. Sanding it removes the last pieces of clay while roughening the surface. Moreover, it makes it easier for the frazzle tape to stick.

Wipe the whole surface area down with the acetone for a final clean.

Carefully wrap the exhaust tape effectually the pipe using at to the lowest degree two layers and continuing for a few inches either side of the leak. Different brands of tape may require dissimilar application techniques, so be sure to read the instructions carefully. Sometimes, the pipe needs to exist slightly warm to ensure a good seal while other frazzle tapes need to exist dampened before awarding.

Finally, prepare the epoxy according to the packet's instructions and spread evenly over the expanse of the leak.

Allow the repair to dry out and set thoroughly before driving the vehicle.

The empty beer can method

empty beer can

This is a method I've found many DIY people applying, too I do non have experience with information technology and I'd rather not recommend information technology.

Who doesn't have an empty beer can lying around? If you don't, drink up then gather together:

a file
fine sandpaper
acetone (or nail varnish remover)
epoxy
a razor blade or arts and crafts knife, and
a couple of hose clamps

File off any rust and so utilise sandpaper to roughen up the pipe's surface for virtually an inch around the hole. Wipe the whole area clean with the acetone.

Then, utilise the razor blade or arts and crafts pocketknife to cut ii patches from the beer can. 1 should be slightly bigger than the pigsty in the exhaust pipe and the 2d i should be bigger than this but not so large that information technology wraps right effectually the pipe.

Next, prepare the epoxy according to the instructions and spread it around the edges of the small patch. Don't apply too much or it might baste through the pigsty into the exhaust pipe.

Employ the patch and concur in identify until it begins to gear up.

Put a thin and even layer of epoxy over the first patch. Apply the larger patch and concur in identify past securing it with the hose clamps.

Using two patches provides a more than secure seal, ensuring your exhaust pipe won't leak.

Replace the exhaust pipe

Ok, not quite a real method.

But if you accept a real old exhaust organisation with large holes and many holes, information technology can be a hazzle to fix it.

If you cannot weld the spot or if there are too many spots, yous should consider replacing the damaged parts completely.
