HiThese codes are often the result of the head oil flow galleys clogged not allowing adequate pressure inside the head to get to the timing drive components. Have you checked the head oil pressure yet?Being its effecting both side of the engine, it less likely to be the electrical side, more so the timing chamge or low oil flo to the timing comonents. It may take me 1-2-3-etc... responses to get the information I need resulting in giving you the answer you need. I can't read minds nor have a magic wand, & I'm not there to see, smell, feel, or hear so I need good information to return a good answer. My normal hours online are 3pm-3am. There are 2 services your receiving 1: from Just Answer whom has already collected the deposit/question value 2: from me (not an employee of the website & have no control over anything except what I type.) You will be asked to RATE THE SERVICE, your rating me, my response, not the website, rating has no effect on your payment, and it DOES NOT close the post. A rating IS REQUIRED, if you can't complete the required rating today, let me know why so I can get you exactly what's needed.Thanks Chris
