Just to put an end to this thread I was across the road from another Hyundai dealer today and decided to walk into the parts department and instead of asking "does this car have hydraulic lifters?", I asked the price and availability of a set of hydraulic lifters for it.
After checking the vin, and referring to parts diagrams, the parts man said I can have a set of hydraulic lifters for $0 - it doesn't have any!
He then asked if I was alright as I apparently my face had turned red and a vein was bulging out of my forehead haha.
After chatting to him for a few minutes and telling him the full story, he basically advised me that if they had done the job properly, when the belt is off you pull the valve cover, unbolt the cams and reshim. Add an hour or 2 labour on top of the timing belt change, a few shims and a rocker cover gasket.
But, because of the sh** advice the initial dealer gave me when they did the belt, if I want the valve gap adjusted I would have to basically pay for another timing belt from scratch.
Will be writing a nasty email to the dealer principal of the servicing dealer - though a lot of good it will do!
