Please take your vehicle to a qualified mechanic. A leak in the intake manifold gasket can cause catastrophic results not only are you losing coolant to the outside but may also be leaking coolant internally which could contaminate the oil and cause the engine to fail due to loss in lubricating properties. Also, if not torqued properly you may have a warped intake manifold. Please see a good mechanic it may cost more but you risk a much larger cost to replace an engine
lower intake manifold gasket or head gasket are the two main suspects. The long block itself is tough, it's the stuff that bolts on that usually fails. Cuz plastic likes to warp easier than metal.
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!
Hello roxanna surf: My name is Roger and I will help you. The problem could be one of several problems. GM has a problem with the intake manifold gaskets leaking coolant useually external but can leak internal also. Check at the corners of the intake manifold where the manifold meets the heads. If you see green or orange drops of coolant or a slimmy build up than the intake manifold gasket is leaking. Idf the leak has been ongoing for some time and the engine has overheatedI would also look at a head gasket, warpped head or even a cracked head as a source of the problem. The engine does not like extreme heat and can have serious issues. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger
engine running lean. Usually caused by vacuum leak. If you have a V engine, the failure is usually intake manifold gaskets. If you have inline (4-cylinder), the cause may be intake gaskets or bad or unhooked vacuum hoses attached to the intake manifold. Check all vacuum hoses for cracks or loose connections. Replace any suspect hose. To find manifold gasket leaks, spray ether or carb cleaner on the gaskets with the engine running. If the engine revs at all, you have a leaky gasket and must remove the manifold to replace. Please let me know if you have any more questions.
Carefully check all hoses & clamps. If leak/seepage not found then check for leak along the intake manifold - the manifold gasket could be leaking and this is quite common.
Hello glennjenkins: My name is Roger and I will help you. You did not say what size the engine was in your car? I will assume it is a 3.8 v-6.The problem most likely is the intake gasket. These engines were built with a intake manifold set made of plastic. Over time they will crack and start leaking. The fix is to replace the gasket set. You should change the oil and filter when changing the intake set. When you pull the intake you will have coolant run into the oil pan. Also when the gasket leaks it is possible for coolant to leak into the oil pan. To replace the intake gasket does require some special wrenches. Such as a inch pound torque wrench and a torques socket for a special headed bolt.

the gasket you had replaced was the lower intake manifold? this gasket can leak coolant and cause white smoke to come from the exhaust. the exhaust is actually single with dual outlet at muffler. when an engine is getting coolant into the cylinder it burns and causes white smoke much like steam. if the engine is running rough and has the check engine light on then it sounds like you have either a leaking intake manifold or problems with the cylinder head or heads. head(s) could have a bad gasket or a crack. only way for sure to tell is too remove manifold or head(s). call the repair shop and demand to have it looked at again. also have another totally separate repair shop inspect it to have a second opinion.
