speakermakers Posted October 15, 2005 Share Posted October 15, 2005 All right after checking a few other threads on the p0420 topic I have decided that I need to eliminate the possibility of a exhaust leak first and then spend money on parts second. So here is the big question. How do you find any and all exhaust leaks? What’s the trick of the pros that works every time? My car is loud, clunky, ticks and rattles like a tractor. This makes listening for a leak imposable. I have tried numerous times. The idea of going to a mechanic scares me. Poor, desperate, and paranoid, please help!

Setright Posted October 15, 2005 Share Posted October 15, 2005 You need the car up on a lift so you can get under it safely. Then have someone else press a cloth over the end of the exhaust pipe to block the flow. This will cause leaks to REALLY start to whistle/roar.

nipper Posted October 15, 2005 Share Posted October 15, 2005 On the bright side, there arent many places for it to leak. Rust will be obvious. Gasket leaks there should be discolloring. If its loud start looking at the cylinder head ports. Wear saftey glasses ..rust is nasty in your eyes. nipper Quote Link to comment Share on other sites More sharing options...
