Car Forum / Toyota / Camry / October 2007Exhaust system leak
Hi, I have a 93 4 cyl camry and I just failed the emission inspection. The guy there told me that they didn't even perform the test because I had an exhaust system leak. Does anyone know how they do the test? What could be the cause? Thanks. be Old exhaust pipes and rubber bushings can flex over the years and gaskets can leak. It may be as simple as replacing some gaskets ($5.99), if you don't have rust-throughs in the pipe itself. It would help to ask the person doing the inspection about the details of the leak. http://www.partsamerica.com/ProductDetail.aspx?MfrCode=FEL&MfrPartNumber=23626&P artType=97&PTSet=A > Hi, I have a 93 4 cyl camry and I just failed the emission inspection. > The guy there told me that they didn't even perform the test because I [quoted text clipped - 3 lines] > > be > Does anyone know how they do the test?

If the engine keeps running, then there must be an exhaust leak along the way. > > Does anyone know how they do the test?

I asked how they do the test because I wander if a clogged catalytic converter can have the same outcome. > I > had an exhaust system leak. == If you truly have an exhaust leak, you should be able to hear it. Most commonly at the flex pipe near the front of the engine. > > I > > had anexhaustsystem leak. > > == > If you truly have anexhaustleak, you should be able to hear it. > Most commonly at the flexpipenear thefrontof the engine. Thanks. That was it, 259$ to replace it :( > > > I > > > had anexhaustsystem leak. [quoted text clipped - 4 lines] > > Thanks. That was it, 259$ to replace it :( == If you want to take the next step, check the "engine moving control rod" AKA "dogbone engine mount" at the strut tower near the timing belt cover. Look for deterioration or cracking in the bushing. If worn and neglected, this can lead to failure in the more expensive fluid filled front engine mount, and eventually the more difficult to reach rear engine mount. Since this short, relatively inexpensive and easily replaced engine brace keeps the engine from moving excessively under load, when worn could also accelerate wear on the flexible section of the exhaust, hence the suggestion to check it. |
