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.
can exhaust manifold leak cause you to burn oil
if your 1987 Nissan pickup leak water from manifold what do we do
Where is the leak coming from. Most likely you will need to replace the exhaust manifold gasket which will require removing the exhaust manifold.
is it hard to fix a manifold leak on a 351 ford engine
The answer is yes. A crack in a manifold is much worse than just the oil leak. Manifold cracks are generally caused by severe overheating or improper assembly of parts. A crack in a manifold can cause oil to leak but the oil leak is inconsequential as the crack renders the engine unusable safely, without replacing the manifold. Running an engine with a cracked manifold is very bad for the rest of the engine and your own safety.

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.
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.
no...sounds like an exhaust leak could also be a crack in the manifold
No. This means that the manifold has an exhaust leak.
The leak would vary on the size of the hole or seal failure.
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.
Sure can. This is very dangerous so have it inspected.
The manifold itself could be cracked. I have a 2000 Pathfinder LE with 100k miles and a 3.3. I noticed an antifreeze leak on the right side of the top of the engine. Using a mirror, I found that under the manifold, there was a nice crack.
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.
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
Sure could. Also the valve covers.
Replace gasket why does gasket keep sliding
By replacing the whole gasket.
bad gasket. needs replaced
On most vehicles, yes.
Yes, that is possible on some engines.
