There is a updated version of the intake manifold gasket set because they are so prone to leaking, a quick pressure test of the cooling system should determine if the intake is leaking or not do not exceed the rated pressure stamped on the radiator cap or serious damage can result

SOURCE: vacuum leak

mine is doing the same, it's your pcv receptor on the manifold. that hard plastic cover is actually part of the intake itself, if it "came off" it would cut your intake in half. that seem seals the two halfs together. you gotta pull the whole intake off and replace it... or jimmy rig it.

Location of freeze plug on 2001 malibu

I had a 2000 malibu 3.1 and the manifold gasket was leaking. Model years affected, 97-04. Check the recovery coolant tank and if it looks like a milk shake instead of coolant, then you have a bad intake manifold gasket. I replaced mine a few years ago and all was fine. Engines affected are the 2.4-3.1-and 3.5, look very carefully around the intake manifold and you will see it if its leaking! operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks. Because oil will mix with coolant if gasket is bad. Hope this helps you out! Good-Day!

Why would my oil get milky in my 2006 chevy malibu

Sounds like you are developing a coolant leak into your oil. Some of these engines have been known to blow an intake manifold gasket and leak anti-freeze into the crankcase. Most times, it is a head gasket that is blown out. Good luck.

Code po174 says to lean on bank 2

This Code usually means that extra air is coming into the engine. The Intake manifold gasket can be leaking or a nearby Vacuum device is broken internally and is drawing in air.

To test for these leaks, with the engine running, you use an old spray bottle of water and spray around the seams of the intake manifold. Any leaks will change the RPM or stall the engine.

Check with an autoparts store for the type of gaskets your intake uses. Some of the V-6 engines used a 2 piece sandwiched design and the two halves had a gasket inbetween. After years of use,the gasket would fail.

My 2002 Chevy Malibu is overheating. I found that

If your car is equipped with a 3.1 or a 3.4 litre V6 and you have preformed all of the above listed work then I would have to say its the intake manifold gaskets. They commonly blow on these motors. Just a design flaw, nothing but replacing them when they leak can fix this. Also run a coolant pressure test on the system to check for minor things like a leak that you cant see from visual inspection. Hope this helps.

My 2002 chevy malibu is leaking coolant

Not sure till you find the leak, it could be just a lose hose clamp which is free if you can tighten it, or it could be a worn water pump and is leaking from the weep hole, and that could be Around $70.00 for the part. At worst it's a leaking intake manifold which is going to cast $900.00 to $1100.00 on the repair. Good luck and keep me posted, be glad to help.
