Finding exhaust leak under hood
Hi all - car is a 1985 Corolla SR5, 224k miles.
When the engine is first started, even if it's not fully cold, I can hear some exhaust noise from under the hood, primarily when accelerating. What would be the best way to pinpoint where it is? It's definitely under the hood somewhere. It goes away after a couple of minutes of driving. Thanks all |

What would be the best way to pinpoint where it is? I would use a smoke machine leak tester. But that an expensive piece of equipment. You can slowly pour some ATF down the intake and the resultant smoke will show you the leak. Probably a cracked exhaust manifold.

When the manifold gets hot and expands the crack typically closes. >Thanks all |

A length of heater hose, used as a stethiscope, is a very useful tool sometimes. |
