lower intake manifold leaking coolant
I noticed some coolant leaking out the front of my engine, where the lower intake manifold attaches. When I took off the manifold, the gasket had corrosion around the areas where the coolant was in the front near the water pump [the oil areas looked fine.]
Any idea what might have caused this? I had cleaned and sanded and brake-cleanered everything, and carefully followed the directions for laying out the gaskets and RTV'ing the corners, and torquing everything down.
Is there a trick I'm missing? I'm trying not to put it all back together and have the same problem pop up.
