What attaches to the exhaust manifold?
A gasket or O-ring (doughnut) seals the connection between the exhaust manifold outlet and engine pipe to prevent leakage. Inline engines will only have a single exhaust manifold, but V and flat engines will have two exhaust manifolds as they have two heads.
Where does the exhaust manifold go in an engine?
An exhaust manifold of an internal combustion engine is the very first exhaust component bolted directly to the engine. The manifold then attaches to the front exhaust pipe, which in turn attaches to other pipes, a catalytic converter and, eventually, the muffler and tailpipe of the vehicle.
What should I do if my exhaust manifold is leaking?
Follow the exhaust system from the tailpipe to the engine to determine the location of the manifold. Some later-model vehicles may even have an initial catalytic converter bolted to the manifold and then attached to the front pipe. Warning. A leaking manifold is unsafe and also harmful for the environment.
Do you have to replace the exhaust manifold when you replace the gaskets?
If any of the bolts are questionable looking, plan on replacing them at the same time you replace the exhaust manifold. Nuts and bolts are cheap. If you can swing the price of stainless hardware, your engine will thank you. Always replace the exhaust manifold gaskets when replacing a manifold.
What happens if you blow out the exhaust manifold?
The same thing will happen if the exhaust manifold gaskets blow out, or the mounting studs break off. Since tubular steel exhaust manifolds typically have better flow, they are most often found on performance-oriented applications, like sports cars.
How do you connect the exhaust pipe to the muffler?
Slide the exhaust pipes together. Slide the pipe from the muffler over the existing exhaust pipe. The muffler should rest directly below the rubber eyelets its mounted to, so the eyelet should hang straight up and down when the pipes are joined properly.
What can I do to stop my muffler from leaking?
Spray exhaust sealant on the ends of both pipes. Spray exhaust sealant on the pipe coming from the exhaust and the pipe it will connect to on the muffler. This will help establish a seal between the pipes and prevent any exhaust from leaking at the joint. Refer to the instructions on the exhaust sealant to know how long to let it cure.
What to do if your exhaust pipe breaks?
Because the muffler and the piping have been held together with the exhaust clamp for so long, they may not come apart easily once the clamp is removed. Spray some rust penetrator where the two pipes meet and try to work them away from one another until they slide completely apart.
What can I use to seal the exhaust pipe?
Spray exhaust sealant on the pipe coming from the exhaust and the pipe it will connect to on the muffler. This will help establish a seal between the pipes and prevent any exhaust from leaking at the joint. Refer to the instructions on the exhaust sealant to know how long to let it cure.
