Exhaust leak at Exhaust manifold to head gasket or oring at exhaust manifold pipe.
A cheaper option for dual exhaust without making it a true dual exhaust from the exhaust manifold/headers. Not much performance gained just appearance.
All a donut gasket does is provide a seal between your exhaust and your manifold. If anything you may get better mileage because there is less restriction on your exhaust. The bad part is you may get some fumes in the passenger area. ==Another Answer== A bad donut gasket could in fact cause these symptoms. It will allow excess oxygen into the exhaust stream, tricking the oxygen sensor into thinking the engine is running lean, making it add fuel and make the engine run rich. This will hurt fuel economy and power.
it may be an exhaust manifold gasket. when they are bad, they make a tapping soud til it heats up and semi-seals itself. it's one thing to have checked.
If you take off the exhaust from the manifold theres usaully a washer there . By taking that washer off you are letting more gases escape therefore making it go faster but make sure that you dont accidently remove the gasket aswell . The gasket is the black rubber piece that stops the exhaust from letting the gases out from where it is connected to the engine . If you do you will here the engine alot more and it is not googd for the exhaust and the engine metal to be touching .
Exhause leak? Bad Muffler? Leaking or cracked exhaust manifold? Bad EGR valve?
The most likely cause is an exhaust leak or a cracked exhaust manifold. While it is also possible that there is a problem with the Camry's catalytic converter, check to see if there are any leaks from the exhaust or any problems with the muffler first.
Yes, if the leak is in the manifold or collector before the 02 senor.
You will see steam come from the tailpipe in the winter which is caused by the hot exhaust coming from the engine making contact with the cold metal in the exhaust system. This is normal and no cause for alarm. However if the white smoke does not dissipate almost instantly and seems to continue you may have a blown head gasket. If the exhaust smells sweet you almost certainly have a problem and the gasket is blown. A blown gasket will destroy the engine in time. If you are not sure have it looked at by a professional.
Depending on the failed section of gasket, either the engine coolant ( anti freeze) will mill with the engine oil making a creamy, expensive mess. or exhaust gases entering the cooling system
check your engine for a cracked manifold (covering of the engine parts and cylinders. also look for any exhaust leaks. it sounds like the exhaust noise isn't making it to the muffler as it should and instead is coming from the engine directly.
Cut the wire, unscrew the old oxygen sensor then replace it with the new one and finally, connect the new wire, making certain that you follow the manufacturers wiring diagram. To find the oxygen sensor, look at the exhaust manifold, then follow it down to where the manifold feeds into the headpipe. The oxygen sensor is the part that screws into the exhaust and has a wire connected to it.
