Can vacuum leak damage engine?

At its worst, long-term driving with a vacuum leak, elevated temperatures generated by running a lean air-fuel ratio could result in engine damage. Lean mixtures can detonate, damaging pistons and bearings. Higher than normal exhaust temperatures can also lead to catalytic converter meltdown.

Is a vacuum leak expensive to fix?

A vacuum leak will often result in rough or slow acceleration because the engine will get the wrong air/fuel ratio when uncalculated air is entering or leaving the engine. A vacuum leak normally results in a lean mixture, and a lean mixture often results in slow acceleration.

Does a vacuum leak affect gas mileage?

A vacuum leak may not always negatively impact fuel economy. If the engine's original air/fuel ratio was set a bit rich (too much fuel), then a vacuum leak can actually help to increase horsepower and fuel economy by restoring the air/fuel balance to its ideal 14.7-to-1 ratio.
