Any idea how long Skoda would give a dealership to change an engine? 

Whats a typical dealers Labour rate per hour?

You'd be best phoning the dealer and asking them.
Swapping the engine might be X-hours but they are likely to spend another few hours swapping ancillaries & making sure it works as it should (or I would hope so).

If you are paying the bill, it is worth negotiating a discounted rate or even a fixed fee if you can.
