coolant issue need help

The valve covers have always been a source of problems for oil leaks. I have ended up using stainless steel Allen head screws with a drop of red Loctite on the threads to keep them from coming loose again. It makes it harder to get them out after the Loctite has set, that's why a Allen head screw works best. I also use a thin layer of black silicone to seal the valve cover gasket in the groove and on the contact side for added insurance.
Another place oil can leak are the spark plug valley plate 14 mm hex plugs if oil is collecting around your spark plugs after sealing the valve covers. A dab of silicone works here as well then torque them down. Keep an eye on your front and rear coolant by pass 90-degree elbows. When they get old or oil soaked they can become soft and rupture. I check by giving them a little squeeze when the engine is cold. It doesn't hurt to get a rag out and start cleaning up to your engine area. That way you can spot new trouble easier plus it looks good!
