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.
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
Faulty intake manifold gasket or faulty head gasket.
Yes. If an intake manifold gasket was not installed properly or has somehow become damaged the engine will pull air through the opening.
There are a few causes: Damaged or disconnected hoses (or component) from intake manifold. Worn out intake manifold gasket. Improper replacement of a part. Cracked or damaged intake manifold.
The year, engine size and if it is the intake manifold or an exhaust manifold gaskets would help.
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.
It would be wise to replace the intake gasket with a new one than to try to fix the old one. How long it would take to replace the gasket would depend on the model, year and engine type you have.
Leak or blown gasket.
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.
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
if its a 3.1, the possibility is the intake manifold gasket!!
I was having a problem with my intake manifold gasket on my 2003 Pontiac grand am and i took it to a shop it was 600 dollars parts and labor you can get it much cheaper i just chose a mechanic i could trust. now it may not be intake manifold gasket the best way to tell is to lift your oil cap look at the backside of it and if there is a blueish tint liquid on the cap then your getting condensation which means bad intake gasket. But it can also be your thermostat housing messing up which would be much cheaper.
