Good Afternoon - I would appreciate your opinions on the following Chrysler 318 1973 -- discovered water in Oil (milky) Pulled heads found pockets of oil in both the Valve Train and Cylinder Heads - Cylinders & Pistons were clean Cylinder Head Gasket looked alright - Removed both the Exhaust elbow and riser. This riser is different - The water passage thru the Exhaust is about an inch or more - On this riser it is about a quarter of an inch - Thanks
