What is leaking? Coolant? if so the intake gaskets are bad. You need to fix it ASAP before you overheat the engine and cause more damage. Dont put water in, it will rust out the freeze plugs.

Go to You Tube Video to find the problems
with that motor & the solution
A local repair shop can check bulletins in their
data base for the fix also
Most likely intake gasket,if you use Dex Cool
It eats gaskets & the vehicle is old ,so you can expect
to be constantly working on it

I have oil in the antifreeze. Checked spark plugs to see if head gasket leak. Doesn't seem to be that. Maybe Intake Manifold gasket? How to check that?


There is no oil in the intake manifold. Assuming you have overhead cams, oil can leak into a coolant jacket past the head gasket or a crack in the head without getting into the combustion chamber. This is likely what has happened. If you need more help, please reply.

intake manifold gasket. when it leaks water will enter a cylinder causing the sprark plug to short out. when the engine gets hot enough the water will cook off in the cylinder allowing spark to take place. 80% chance intake manifold gasket, buy the upgraded part. 20% chance head gasket. Take the intake off and check for broken intake manifold gasket then buy parts.

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.

2000 chevy impala ls - oil spray under hood inline with serpentine belt


You may have a lower intake manifold gasket leak (or a head gasket leak-slightly less probable) the lower intake can leak onto the serpentine belt and fling oil (and/or antifreeze). The lower intake manifold gasket is usually the culprit here. There is much information about changing it if you are inclined to do it yourself. If not, expect around 800 to 1200 to fix at dealer/mechanic. This is usually accompanied by (but not always) oil in the antifreeze, or antifreeze in the oil...
