How to Fix a Manifold Leak
Having a manifold leak in your vehicle can cause it to have performance problems. Making sure that the leak gets fixed is important if you want your vehicle performing at its peak. Because the intake manifold is primarily responsible for distributing the mixture of both fuel and air to each of the engines intake ports, fixing these types of leaks is paramount when trying to get the most out of your engine.
Instructions
- 1
Check your vehicle to see if theres any oil leaking from the manifold. Identify where the leak is.
2Disconnect the battery. Remove the nylon fuel rail and the air ducts. Once the fuel rail is removed, press the wires of the injector connectors with your fingers in order to detach them. Use a screwdriver to help make the rubber rings loose. This will aid in removing them easier.
3Use a socket to take the throttle cables, alternator brace and throttle cable cover off. You must also remove from the intake manifold, the throttle body. Once this has been accomplished, you will need to loosen the two nuts that are attached to the EGR pipe and detach that as well. When you do this, youll find a gasket on the EGR pipe, but leave it there for later use.
4Inspect the manifold of your engine. Remove any gaskets that seem to be loose or broken, and replace them. Clean existing gaskets with WD-40, and make sure theyre free of debris by wiping them with the cloth. Replace all of the parts you just took off. This should fix the leak. If it does not, take your vehicle to a professional.
