I have the same issue with my 2005 325xi, and was told at the shop that it's a cheap part, with an inner core made of resin rather than steel, so extreme temps, a big bump in the road, etc. could cause it to crack, unfortunately.
A bad intake manifold or manifold gasket can cause water to leak into the oil. Some newer cars have plastic manifolds and they will crack from age.
THE CAUSE COULD BE A STUCK THERMOSTAT , OR A BLOWN HEAD GASKET, OR A LEAK IN THE INTAKE MANIFOLD OR INTAKE MANIFLOD GASKET. A CRACK IN THE INTAKE MANIFOLD IS VERY COMMON.. NORTY
Your intake manifold probably has a crack in the water jacket.
Do you mean intake manifold OR exhaust manifold. Need to know NEUTZ.
No, the head gasket is underneath the heads where they mount onto the block. Your intake manifold is bolted to the top of your heads. Some motors have coolant that circulates in the intake manifold ( I don't know what year or make your vehicle is ) so I would check my shop or repair manual. There could be a crack where the coolant flows through your intake manifold or one of the manifold gaskets may need replacing.
it can cause excessive noise and excessive heat to electrical lines under the hood. It is also a place for CO gases to build up and find a way into the drivers compartment. Yes, a lot. In the exhaust manifold anyway. In the intake manifold it wouldn't run.
If it is a gm 3800 you need to replace the upper intake. It has a crack in it.
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.
It could.
if it is the exhaust manifold ,yes. if your breathing in those exhaust fumes you can get carbon monoxide poisoning
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.
Us a small propane torch NOT LIGHTED to supply a little fuel to the area with the engine idling. When the propane finds a manifold crack the engine will increase its rpm. Use proper ventillation and be careful.
