If it still resets, swap the Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake with one of the other solenoids.4. Check for the code to set for the new location of the solenoid.5. If a new code sets, and code P0011 no longer sets, the solenoid is defective
I included that archive report for you although from the pic i seen your engine looked clean. You mentioned it ran fine for 50 miles or so, When you done the heads did you do anything to address oiling, as in remove pan, clean screen, flush system
Excellent information. About the flushing I have encountered problems with the timing solenoids on this engine multiple times and not once but every single time the problem or the fault of it could be traced back to oil pressure. The problem with these and all timing solenoids is that they are the very last part to get oil. What I usually see is sludge and deposits from the lack of proper maintenance. The screen stops up in thr oil pan. In most cases a good flush product will do the job. Bg chemicals has the best for my money. We have these here in the shop I'm sure a repair shop in your town would sell u the kit. Lets start with a good flush of oil system.
