2000 S40 P0014 OBD Code

The Dreaded P0014 Timing Over Advanced trouble code
Ok I have a 14 year old S40 this is a chronic and reoccurring trouble code on these models and most other forums on the topic point to replacing or cleaning the solenoid, which is the first usual suspect. I have used 3 rebuilt or used solenoids on this car and the dreaded P0014 still throws occasionally It threw again this winter in cold operating temperatures. The solenoid "switches over" , which I tested and verified by applying 12 volts to it when off the car. Ok Gang here's two remedies that will fix this once and for all. Believe me I have a 2000 s40 with 133K on it. . First, sometimes the timing is over advanced because the timing is over advanced. Many a CVVT solenoid has been sold and installed without fixing this . check the timing belt tensioner!!!!! Really. the indicator must be dead center on a cold engine and cold ambient temp. These slip or loose tension and get out of adjustment.. Ok the second problem . Use ONLY 10 30 weight oil on these babies. Regardless of temp range. The dreaded P0014 code was throwing every 30 or 50 miles on me. I changed the oil back to 10 30 AND used at least one quart of Marvel mystery oil on that last change. It had been throwing me a P0014 every 30 or 50 miles or every other morning on a cold start up. I driven 300 miles since I did the oil change and used a quart of the Mystery oil to thin out the oil some and clean out the "gunk" or sludge.
So far No dreaded P0014 is being thrown and it seems to be idling and accelerating a lot better.
