By intake, I assume you mean intake manifold? Typically if your intake manifold gasket is leaking, it can have one if not several of these signs. First your Engine typically will run or idle rough, due to a vacuum leak. You could see visual signs of exhaust, anti-freeze, and or oil leakage. On some Engines you might even see your oil and anti-freeze getting mixed together in your oil pan. You also could see white exhaust fumes out of your vehicle's tail pipe, due to anti-freeze in your exhaust system. These are just a few of the signs of a leaky manifold. If you re-ask the question with make, model, and engine size I could answer with more precise answers.
The Intake gasket is leaking, NOT THE HEAD GASKET. Replace the intake gasket
Intake manifold gasket
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.
You either need a head gasket or intake gasket.
Intake gasket leaking on the inside of engine.
I just had the intake manifold gasket replaced on my 96 century yesterday and my bill was $450 but my gasket was only leaking out. If its leaking into your oil it may be more.
NO NO, That would be a intake gasket leaking, not a head gasket. You also should check where the heater hose hooks up on the intake, it may be leaking.
Look for leaking antifreeze/coolant. Usually you can see it leaking around the top of the engine. Also check your oil, if it looks milky it has been mixed with coolant and you intake manifold gasket is leaking. That being said, it is possible to have a leaking intake gasket with no sign of leaking antifreeze. Most intake manifold issues/leaks are coupled with poor engine performance and even sputtering and lack of power.
Most likely the intake manifold gasket is leaking.
