Episode 177 - Timing Chain and Oil Pump Replacement 2001 Ford F-250 Superduty 5.4L 2 Valve

Welcome! This is a long one. In this video I cover how to do a complete timing job, covering all the teardown steps, the work itself and then covering highlights of putting everything back together. I also cover how to remove and install a new high volume oil pump. Lastly, I cover what to do if the oil pump won't prime after you put everything back together. This is a very detailed video with a ton of good information so make sure you move through it to find the section you need to get the job done. Be mentally ready if you decide to this work. As the 5.4L 2 valve is an interference engine, if you get this repair wrong the valves and pistons WILL wind up hitting each other. This video is largely based on the following videos from the following Creators:

I have a better grasp on the two styles of tensioners the 5.4L uses and how they work. The tensioners used by the 2V 5.4Ls is the cast iron one seen in this video. It primarily uses spring pressure to put tension on the timing chain and uses a ratchet mechanism to hold that tension. However, to get the perfect tension oil pressure is also to push the piston on the tensioner exactly where it needs to be. This is why the tensioners have the cavity in the back for oil flow. They don't have o-rings on them, but have a machined flat back that is the seal itself. This seal can leak, but it's less prone to than the composite tensioner introduced with the 3V 5.4L
Introduced with the 3V 5.4L is the composite tensioner. This one is purely driven by oil pressure and features an o-ring that allows the tensioner to seal against the block. It is this composite tensioner that has the issue of the seal blowing out, then leaking out oil pressure leading to HLA noise and other issues.
