Thread: 327 running hot

You can do a compression test. If you have a crack block it would usually show very low compression between two adjacent cylinders. Another thing that would cause a crack is overheating which will cause the head to contract, but this usually will cause the head gasket to fail. Is you oil white or cholate color? Did you put the head gasket on and maybe it moved? Do a compression test first.

the oil is kinda funny it has about 15 minites on a fresh 5 1/2 quarts adn i drained it, the color is kinda dirty then clears up as it finishes draining, not white (milky). no white smoke while running, no white specs on spark plugs. but runs hot after 10 minutes, and i get quite a few drops of coolant out of the drain plug and the oil is watery
