these engines are a problem with this code. any dirt or sludge restricts the oil passageways.
to avoid any more code issues p0017 change oil only when engine is hot. use synthetic oil. do not use fram filters. wix/pure one purolator/ac delco are much better at removing particles and have a stronger filter media. lifter leak down is from carbon on the hydroylic lifters therefore use 5 OZ of marvel mystery oil to the crankcase to clean these lifters.
the part that usually causes the code is the camshaft actuator solenoid valve . this has a screen so any dirt/sludge creates this issue. removal of the part and inspect the screen.
many have this problem. increasing oil viscosity may have reduces lifter leaking off. if the lifters have bleed off the timing will be off for a short time. marvel mystery oil does a great job of cleaning the lifters.
