Replace the manifold gaskets.

Word to the Wise: It would help to know what caused the leak. Bolts not tightened in correct pattern or torque, or just old age? Also, if manifold is aluminum, don't gouge the gasket mounting surfaces, only smooth w/ the yellow fingers tool you can get from SnapOn, or use fine sandpaper and a sanding block. Don't polish the surfaces either, or the gasket will slip or blow out.

Depending on what engine you have, Intake manifold; vacuum leaks, coolant leaks internal and/or external, oil leaks. Exhaust manifold; exhaust leaks, backfires.

Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out

A good place to look for Coolant Leaks is around the Intake Manifold, as if the engine has recently started to run rough, this could be a definite sign of a bad intake manifold gasket. Unfortunately, the cost of this type of repair at the local Clip Joint can end up costing you $800.

Not that I've heard of. Replacing the gaskets and inspecting the manifold for warping or cracks is the best way to stop intake vacuum leaks.

Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.

usually your intake manifold is ok...the manifold gaskets are prone to failure..they are plastic with rubber impregnated seals...if the manifold is actually pitted, you can repair with JB WELD then sand smooth.... ase master certified tech

Could be the intake manifold gaskets are leaking.

Yes, You have to remove the intake to get the heads off.

You can find a diagram of an intake manifold for a Kia Sportage at major auto parts stores. You can also find it in repair books at the library.

Have the head gaskets checked and intake manifold gaskets checked for leaks. The 3.4's are known for head and intake leaks! Or a bad thermostat.

If the intake manifold gasket has failed then it can cause many issues. Air leaks, known as vacuum leaks, will cause an erratic idle, stalling, and fuel problems.

It Is caused from The heater Hose Located Under The Intake Manifold ..In Order To repair It You have To remove the Intake Manifold.....

You do not repair a head gasket you just replace it. Major repair involving removing the intake & exhaust manifold, and the heads.

i suggest you get a repair is not easy

cry because its probaly lower intake manifold leaking which is 500-700 to fix

between the head and intake manifold

Between the intake manifold and the cylinder head.

You must remove the exhaust manifold, intake manifold, and then remove the head. This is a major repair that should only be attempted by a pro.

NO additives are recommended by any good mechanics. Only the full repair is best especially whem dealing with coolant leaks. Usually intake leaks are from years of corrosion the coolant will turn to acid in most oif todays cars if not treated you will have much internal damage. the external leaks will only show up when damage is done. Dont write off the vehicle it ,will be much cheaper to repair than pay the extra cost for insurance ,interest loss of value for new cars.....

Under the intake manifold. where is the intake manifold!
