I replaced uper and lower intake gaskets, still leaks anti-freeze

On the under side of the intake manifold (under the plenum and fuel rail), there is a heater coolant tube that runs from the front of the manifold to the back. Has a o-ring seal and that o-ring eventually wears out and begins to leak. Depending on the size of the leak, could see some steam from overheating/low coolant to coolant leaking off the back of the engine intake valley to smelling coolant inside because of the air flows to the interior system. Two buck dealer part but have to R&R the entire plenum, fuel rails and intake manifold to get to it.

no,the weep hole does not feed the valley. you need a shop to insert a dye to determine the point that is leaking. Roy

the 2.7 motor the water pump is driven by the timing chain and the 3.5 motor the water pump is driven by the timing belt that pump has a weap hole at the bottem of the water pump and when the pump is bad the antyfreeze leaks inside the timing cover,now you said the leak is under the intake then something is wrong in that place, the 2.7 water pump has a weap hole in it mating to the block that send the coolent to the left side front this is a weap for that water pump. if its wasnt set up that way coolent would be in the oil and you would have motor damage, we would be glade to look at your car for you, so give us a call!
