Time requirement for injector removal

[JHZR2]

Hi,

Anyone have an estimate of the amount of time it would take a first-timer to remove the injectors from a 617.952? I have recently acquired the two hazet tools, for the injector and the hard lines.

it seems straightforward enough, and there are DIY threads when searched, but I'd love a guesstimate of the time to do all five inectors.

Also, any last-minute tips? How do you deal with the diesel fuel that is bound to leak? How much can I expect? What is best used to plug the injector holes when they are out for refurbishment?

Anything to be concerned with if they have not been removed on a 160k engine?

Thanks!
