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.
A manifold leak is usually in reference to a failure of the intake manifold gasket. It can leak air, oil or coolant. It can leak to the outside of the engine or internally into the engine. A manifold leak may also refer to the Exhaust manifold that is leaking exhaust fumes from a bad gasket or a crack in the manifold.
The leak can be from a cracked manifold, or from a bad gasket where it attaches directly to the engine. This leak is before the O2 sensor, so gives a false reading and may remain undetected. This is a serious issue! Exhaust leak from the manifold will allow the harmful CO2 emissions to enter the cabin. Exhaust leak will also cause decreased performance of your engine, and decreased fuel economy.
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
cracked head or bad gasket
If it is leaking from a bad head gasket, it is because of a bad head gasket. If it is leaking from a bad intake manifold gasket, it is because of a bad intake manifold gasket.
Bad engine seal? Bad oil filter? Leaking valve cover gasket?
A bad cylinder head gasket.
Fixing a leak depends on where the leak is and the severity. An exhaust connection could be loose or a gasket is bad. If there is a hole in a pipe there is a possibility that the hole can be welded, taking care to stay away from fuel lines or anything flammable.
no it will not. Bad rings will do it, Valves not seating in the head, Bad head gasket. Burnt piston will do it . These are things to look for.
Yes, those exhaust gases are extremely hot and can cause the alternator to overheat. Not only that but that carbon monoxide can enter the vehicle and kill you.
