If you smell gaseous odors while your Honda CRV is running, you should inspect the exhaust system immediately. Clicking, rattling or sputtering of moisture out of the tailpipes while it idles are also indicators that there may be a problem with the exhaust system.

Things you need
- Socket wrench
- Hoist or creeper
Use a socket wrench to remove the cover on the exhaust manifold located on the driver's side of the engine block. Check that the bolts on the four tubular pipes are secure and the gaskets aren't worn. Replace any missing bolts. Look for moisture buildup or cracks on the manifold.
Raise the vehicle on a hoist or hydraulic lift. You should be able to use a creeper to slide under the CRV if you prefer and it's not too low to the ground.
Shine a flashlight up from under the SUV to inspect the gaskets and the bolts on the underside of the manifold. Use the light to look at all the other parts of the exhaust, including the catalytic converter, muffler and tailpipe. Make sure all the connections are tight.
Tap gently with a hammer along each piece to locate any weak sections. Feel along the entire system for holes, cracks, rust or loose connections.
Check that the hangers and clamps are securely in place and not rattling around.
Lower the SUV or slide out from under it after you've examined the exhaust system.
Tips and warnings
- Take the CRV through an underbody car wash regularly to remove mud and grime that can cause corrosion on the exhaust system.
- Let your Honda CRV cool down for at least an hour before inspecting the exhaust.
