You can try a temporary fix by applying an epoxy to cover the crack. (I assume that is problem - it is cracked. Common problem for the Protege) However, that is not a good fix, as far as I know. It might be an improvment for awhile, but that's all. Ask a good auto parts store for high temp epoxy. Another method is to braise with silver or some other type rod. You can look up "how to braise cast iron" on Harris website or something. There are charts saying the type rod to use. To weld it this way takes skill and tools and REMOVING THE OFFENDING PART. Once you have the manifold off the car, you light as well replace it with a new one. Repacement is probably cheaper than the cost of theBTU's required to braise it properly.
If the exhaust manifold gasket is leaking the only fix is to replace it with a new one.
Where is the leak coming from. Most likely you will need to replace the exhaust manifold gasket which will require removing the exhaust manifold.
An exhaust leak is usually the result of a bad gasket or a cracked manifold. For a proper fix, either the gasket or both the manifold and the gasket must be replaced.
unbolt the head pipe then the manifold.
Your catalytic converter is at the top of your motor at the exhaust manifold take out the 4 14mm screws that connect your converter to your manifold drop down out the bottom of engine and replace another really simple fix
Need to know if it is the intake manifold or an exhaust manifold and what is wrong with it.
what is the cost of repair of Toyota 4runner exhaust manifold
No. which manifold gasket are you wanting to replace? Intake or exhaust?
It sounds like you either have a leak at the exhaust manifold or the intake manifold. Most likely is the exhaust.
If you do replace it correctly, it will work as designed.
The 2002 Ford escape exhaust manifold will cost approximately $550 to replace. The manifold will cost $300. The labor cost will consist of approximately 4 hours of labor.
All you have to do is look at your exhaust manifold there is a sensor screwed into your manifold ,that is plugged into a connector on the left side of motor unsrew the sensor and unplug the sensor wire and that is all you do and replace with a new sensor really simple fix
