HOW TO REPAIR AN EXHAUST PIPE WITH A TIN CAN

A new exhaust pipe for a car can be very costly. A quick and effective method for patching a hole in an exhaust pipe is using a tin can. Exhaust pipe wraps can be ripped apart by exhaust pressure. By wrapping a tin can around the hole in an exhaust pipe, it creates a seal that lasts without the cost of labor and new parts.

Properly Jacking Up Your Vehicle

Ensure your vehicle jack and jack stands are in proper working order and have the capability of lifting your vehicle prior to jacking up vehicle.

Find the jack point on your vehicle

If you cannot locate the jack point, use the frame of the vehicle or a solid component of the sub-frame.

Use jack to lift the vehicle high enough to be able to work underneath

Be cautious. Vehicle may shift if jack is on wheels and ground is not level

Place jack stands underneath vehicle at the frame or solid parts of the sub-frame.

Release pressure from the jack and place most of the vehicle weight onto the jack stands.

Once weight is placed on the jack stands, start to pump the jack until it begins to raise the vehicle again. Do this to have 3 points of contact on the vehicle to make it as stable as possible.

Remove handle from jack if possible and set off to the side.

 

Preparing Materials and Exhaust Pipe

Obtain a tin can. The best tin can to use is a soup cans about 4 inches in diameter.

Use tin snips or heavy duty scissors to cut the can up the side and to cut the bottom off the can

Be very careful cutting the can, the edges are extremely sharp. Wear thick gloves.

Set cut can off to the side where it won’t be in the way.

Use wire brush to brush off any debris that will hinder the can’s seal against exhaust pipe.

Safety glasses are recommended for this step due being under the exhaust pipe you are cleaning.

Wrapping the Can Around the Exhaust Pipe

Form can to the shape of the exhaust pipe over the hole, and where the two edges will overlap.

Unscrew completely 5 #28 hose clamps.

Place all 5 of the clamps equally over the can.

Begin to screw the clamp on one of the ends until the clamp can no longer move.

Begin to screw the next clamp until the clamp can no longer move. Continue this until all clamps cannot move.

Return to the first clamp and tighten until the clamp cannot be tightened anymore. Continue this step for the remainder of the clamps.

When clamps are completely tightened, the screw may skip and loosen depending on the diameter of the exhaust pipe. If this occurs tighten clamp again to a point it will not skip and loosen again.

Start the vehicle to ensure the exhaust leak has been fixed.

If the exhaust leak is still present, recheck the clamps to ensure all are tight and ensure the can is completely covering the hole in the exhaust pipe.

 

Lowering The Vehicle

Raise the car jack to where the vehicle is lifted off the jack stands.

Remove the jack stands from under the vehicle.

Slowly lower the vehicle back onto the tires.

Remove the car jack from under the vehicle.
