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.

User Avatar

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.

Need to know if it is the intake manifold or an exhaust manifold and what is wrong with it.

User Avatar

No. which manifold gasket are you wanting to replace? Intake or exhaust?

User Avatar

If you do replace it correctly, it will work as designed.

It sounds like you either have a leak at the exhaust manifold or the intake manifold. Most likely is the exhaust.

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

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.

You have to remove the exhaust pipe from exhaust manifold on starter side. Now you have access. Get exhaust pipe to exhaust manifold gasket first, you will probably need to replace it after taking them apart.

its screwed into the exhaust manifold,undo wire and unscrew at manifold.

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

remove the intake and exhaust manifolds. there are bolts that attach them onto the head and there are bolts near the carburetor that attach the intake manifold to the exhaust manifold.

If it's an automatic you will have to remove the exhaust manifold because the thermostat is located on the backside of the engine on the driver's side under the exhaust manifold.

If you aren't hearing a lot of exhaust noise and you're just getting smoke, you have either an oil leak or antifreeze leak that is getting on the exhaust manifold. If you're getting oil on the manifold you have a fire hazard and should take care of the problem immediately. If you hear exhaust gas leaking around the manifold you need to replace the gasket or possibly the manifold is cracked and you need to replace the manifold.

User Avatar

The exhaust manifold needs to have a gasket in place to help seal the juncture between the manifold and the engine. After the gasket and gasket sealer are in place, tighten the bolts for the exhaust manifold. The exhaust pipe can then be replaced on the new exhaust manifold.

$300-$350 depending on the shop.

The purpose of the exhaust manifold is to connect the exhaust ports on the cylinder head to the exhaust pipe.
