If the manifold is leaking you'll be able to look at the edges and see exhaust residue at the leakage spot. You may need a flashlight and inspection mirror to see under the pipes. It's easier to spot if you look under the hood at night with a light and no other ambient light sources around the car/engine. If you've got a feather duster, you can also use it to move around the manifold edges; if it's leaking, you'll see the air blowing it. Just don't use any duster that's polyester or plastic, as it'll melt when it touches the engine.
As far as driving, if it's bad, I wouldn't recommend it. Even if it's small leak, you run the risk of carbon monoxide poisoning in the car, which can creep up on you until it's too late.
If you must, then drive with all the windows down so you've got plenty of ventilation.
can exhaust manifold leak cause you to burn oil
Where is the leak coming from. Most likely you will need to replace the exhaust manifold gasket which will require removing the exhaust manifold.
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.
No. This means that the manifold has an exhaust leak.
Exhaust leak at Exhaust manifold to head gasket or oring at exhaust manifold pipe.
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.
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
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
A leak in an exhaust manifold will be very loud. The car may also experience issues stalling or running to lean since the oxygen sensor readings will be off.
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.
Overheated, exhaust leak, oil leak on manifold-hard to speculate
probably an exhaust leak, at or near the exhaust manifold
