I pulled the valve cover off and discovered a light film of sludge in the cylinder head just like in the oil pan. To me this indicates that the motor has been rebuilt and has very low miles.
My question is should I use non detergent oil or switch to detergent and if detergent, what viscosity?
While at it, should I keep the canister oil filter or use a conversion spin on kit and if so what brand that won't leak?
