The old clunker's exhaust was blowing a bit, so I sealed it.
Then it fell off. It had rusted right through between the catalytic converter and the silencer.
"You know what you're going to have to do, don't you?", said Kitewife.
"No, write an Instructable!"
[Some of my more recent projects are now here.]
Step 1: Materials and tools.
This is a fairly simple job (it only took me half an hour), but you do need some specialist materials:
- Wheel ramps or axle stands. Do NOT attempt any jobs underneath a car supported just by a jack. People die like that.
- Eye protection (unless you enjoy rust, dirt and toxic chemicals being dropped in your eyes...?)
- Metal snips.
- Jubilee clips.
- Screwdriver (flat-head, to match the jubilee clips).
- Assorted pliers, spanners and thumpy things.
- Exhaust repair paste (available from any car spares store).
- An empty tin can.
You should also wear appropriate clothing - spare a thought for whoever does the laundry in your home, and be aware that you could quite easily get un-removable gloop on your clothes. An old hat might help as well.
Step 2: Find your problem.
If your exhaust isn't snapped through, but is still blowing, then you will be able to hear it - your car will sound as if the engine gained an extra couple of litres.
If you can't see the hole, just move your hand along beside the exhaust until you feel the breeze of escaping fumes - feel along both sides, above (if you can) and below, but be careful, the exhaust pipe gets a lot hotter than you'd think.
