I have a 4.7 L 2000 Durango I've been trying to fix. It came to me running only on the passenger side because the cam drive pin on the drivers side was sheared. Removed heads, replaced gaskets and cam pin and timing chains/gears. Now that it's back together, the passenger side cam is 90 crank degrees advanced with all the timing marks spot on.
Here's a video showing the timing marks. Ignore the audio about not knowing the cause. The cause is the pass cam is advanced. But I dont understand how or why it is. This is the reason for this post and the answer I'm looking for. When I took it apart this last time it was attempting to run on the drivers side but has no compression on pass side.
