OK I changed the map sensor and the idle air control motor. It cleared the codes. I still have the code 67. at idle 400 rpm's the timing is moving between 5 deg btdc and tdc. When I rev it up it goes beond the marker btdc. All good. I started adjusting the valves on the driver side. I have one rocker that is shooting a stream of oil out and others just ozzing out. a few are not getting any oil. What do I need to do about that?
