Water in the oil doesn't happen from a leaking intake valve. You may have a crack in the head near the intake valve, or you may have a blown head gasket. In either case, it's a big job, involving removing the cylinder head(s) and either replacing the head gasket or replacing the cylinder head. (Attempts to repair a cracked head don't usually work out too well -- better to get another one.)

Coolant or water in the oil can be from a head gasket leak, but it can also be an intake manifold gasket or a crack in the block or head etc. I would begin by removing the spark-plugs and then pressurizing the cooling system and checking each cylinder for signs of coolant entering them. If the cylinders stay dry and coolant goes into the oil during the test you most likely have an intake gasket that's leaking. Don't run thee engine with coolant in the oil or you'll have catastrophic damage!

03 chevy malibu is overheating and water/coolant levels are being depleated very quickly.


What motor does it have. If it is a 3.1 the intake manifold gaskets are bad and it leaks internally. I have repaired more of these that i can count.

The first thing i would do is put the coolant system under pressure with
Cooling System And Pressure Cap Tester. if there are any leaks you will find them with that tool. Also check the oil and see if coolant is mixing with it, if there is you may have a bad head gasket or possibly a cracked engine block.

01 pontiac gt overheating. if a/c or heater on it


It may be the intake manifold gasket that has gone bad and you may be losing the antifreeze in your engine. Pull the oil dip stick out and see if it' over filled and look under the oil cap, look to see if there is any sign of antifreeze in your engine oil. Under the cap would have a milky brown sludge and under the PVC valve too, if there is then your engine is on it's way out if you do not repair the leak. Antifreeze is corrosive to the engine bearings and it's been know that as low as 1000 miles will cause the engine to go bad with antifreeze in the engine. The intake manifold gasket is known to go bad in the 3.4 liter engines till 2004 where they came up with an upgraded gasket. Good luck and keep me posted.

If you have water in your oil, you most likely have a blown head gasket. Shouldn't drive it until you get it fixed, that can ruin the engine. If you keep putting water in, it will keep leaking into the oil.
