I completed the compression test on all 6 cylinders and they all gave back around 190psi with 5 cranks. So the engine isn't completely ruined. However there is still incredibly reduced power after clearing codes and trying to drive. After clearing there is 2 permanent codes P054B and P13B4.
Next step is to borescope the pistons and see if there's any signs of the pistons hitting the valves.
What do you guys recommend after that? Maybe get the timing fixed?
Thanks
