Better to replace the entire camshaft cover as they call it. last time I checked was 40 bucks on ebay. 70 inch pounds of torque as I recall for all 15 bolts. Those bolts were always working loose, but never got around to putting a dab of Loctite on the threads. Plastic is the problem.
Ha, tend to go way back, flatheads were never a problem, neither was my 41 Chevy with an inline six and OHV's no cams, had deep wells. 49 Olds V-8 sure had this problem, stamped steel valve covers with a cork gasket, was always dripping oil on those red hot exhaust manifold, smoke, but never and engine fire. Still have two of these engines, took Fel-Pro to solve this age old problem.
Maybe Fel-Pro could solve this plastic camshaft cover problem, GM sure can't, yours could still be covered under warranty. And is putting plastic on top of a 375*F head really a good idea? Coolant temperature is 220*F but also connected to a very hot exhaust manifold with good thermal conductivity. With all the warranty repairs, GM could have saved money by using aluminum.
