Hi, my 5.0 n/a is leaking oil from the camshaft covers, so I will replace them in the near future when time permits. I'm just scoping the amount of work it will require and any other tasks and parts I should take care of at the same time. Fortunately, I don't have to remove a supercharger. It looks to me that getting access to all the bolts is the most difficult part of this job. There's quite a bit of stuff that needs removing from the engine bay before even getting close to any camshaft cover bolts. I wonder if anyone with experience of this task has advice they'd like to offer? What else should I be considering doing at the same time? I will change the spark plugs but not the coils (no codes or apparent problems with the coils). I believe there isn't a need to pull the injectors, so I'll be leaving them alone. Can anyone tell me the size of the upper o-ring on the injectors? I'll need to replace those. What else? Thanks!

 

You will need to pull the injectors to get the covers off. Very difficult to do in car. I would drop the engine and transmission and change the plastic coolant pipes and plugs also. You may also want to change water pump and timing chain tensioners and guides also depending on condition. Just finished doing mine.
