You look to be having oil pressure and flow issues from a weak pump or sludge buildup or oil flow path restrictions in the head and timing drive components. Have you ran a oil pressure test on both heads and the block?

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.

Thanks Chris

Thanks for checking the pressures. What pressure reading did you get on the block, passenger head, and drivers head?
