Intake Manifold Question
I've had on on going coolant leak that required adding a gallon of coolant about every 500 miles. There were no visual signs of the source of the leak. Compression, vacuum, and coolant system pressure test did not indicate any problems. I noticed a puddle of coolant in the valley underneath the intake and believe the source of the leak is the heater hose that runs under the manifold.
I've removed the intake and would like to get your opinion on the condition of the ports leading into the head. The coolant ports have about a 1/8 film of coolant sludge built up on them. All ports are covered with a wet black grime; some ports on the left bank are only partially covered. The valley between the heads has puddles of coolant and oil. The coolant has left a very slight depression on the surface of the head.
Can a gasket sealer be used to "fill" the depressions? If so, what kind.
Is this normal for an engine with 135000 miles on it?
I've attached a picture of the port in my gallery.
Thanks

Intake Manifold Question
My intake manifold has minor corrosion around the coolant ports. Can I use a gasket sealer around these areas when I install a new gasket? If so, what type of sealer is best?
Thanks

Everybody has a favorite sealer and there are as many opinions as there are products.
I use either "gorilla snot" 3M yellow or black weatherstrip adhesive or copper or red RTV. Low-temp RTV works but if I have high temp RTV I can use that on all RTV-able surfaces.
Whatever you use, don't make the common mistake of using too much.
