How to Spot an Exhaust Leak Early
Exhaust leaks whisper before they roar. A Cranbourne West specialist explains the early signs you can catch.
The early signs
A leak announces itself as: ticking from the engine bay on cold start that fades as metal expands (manifold or joint), a subtle deepening of the exhaust note, black sooty streaks at pipe joints (carbon blowing past), a faint exhaust smell with the windows down at idle — or fumes inside, which ends the DIY portion immediately.
Underneath, rust flakes at seams and a muffler weeping at its crimp are the visual version.
What to do with a suspicion
Fume smells in the cabin mean windows down and straight to inspection — carbon monoxide is odourless and rides along with what you can smell. For everything else, early is cheap: a joint gasket or a clamp today versus a section next month.
On the hoist we find leaks in minutes — soot trails point like arrows.
