squeeking from exhaust manifold is caused by a leak allowing exhaust gas to leak. it will only get worse as time goes on unless it is fixed
Valve cover gasket
No. The exhaust manifold only carries burned exhaust fumes from the engine to the rear of the vehicle. It has nothing to do with the oil or fuel system. It also cannot prevent the engine from starting. However a clogged catalytic converter can cause the engine not to start. Fuel in the oil is caused by a leaking injector on a FI engine or a bad needle valve and seat of an carburetor engine.
It could be a head gasket or a cracked head. Look at the exhaust manifold for each cylinder on the side that has the white smoke, the cylinder that has the leak will cause that port on the manifold to get super hot. One way to quickly identify which port is to spray some cheap black (or color of choice) paint on the exhaust manifold and fill the radiator and start the engine. The paint on the bad cylinder will burn off first.
No, it will just make the car loud.
Most probably, you have a valve cover gasket that is bad, and the oil is dripping down onto the exhaust manifold, and is being burned. Replace the valve cover gasket.
can exhaust manifold leak cause you to burn oil
No but an engine running like that can damage the valves.
exhaust?
If it is running loudly then there is an exhaust leak either at exhaust manifold or some where else in the exhaust pipes. Bad exhaust muffler could also cause this. Hope this helps.
if it is the exhaust manifold ,yes. if your breathing in those exhaust fumes you can get carbon monoxide poisoning
A broken piston ring is the most common cause of water in the exhaust manifold. A bad valve in the cylinder head can also cause the problem.
Yes.
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.
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
Valve cover gasket
It could.
Advanced timing can cause that to happen
