Default 2005 2.5RS burning oil?

I recently bought a 2005 impreza rs 2.5l m/t. The vehicle appears to be losing about a qt of oil every 1k miles. There's no burning smell, visible oil leaks, and the plugs don't look overly oil fouled. The car has 111k miles on it, and according to the dealership and carfax report it had a short block replaced around 50k miles. I'm leaning towards valve stem guides/seals and or piston rings. The rings seem unlikely as it has less that 60K on the short block. However since they didn't replace the heads and most likely did not do a valve job, it seems reasonable that the valve seals are leaking. My question is can the valve seals be replaced with the engine still in the vehicle or with the cams still attached to the engine? and if it is the oil rings can the pistons be removed and re-ringed without removing the engine from the vehicle and splitting the case? As far as parts for replacing the valve seals, does anybody make a problem solver kit? I'm leery of replacing the seals with oem equivalents if they're going to have this problem again. Any help is appreciated.

Subaru engines burn oil normally.. especially at the 100k+ mark its just in the nature of the beast.( i usually add a quart in between oil changes) Just check to make sure your head gaskets aren't leaking which they tend to do at that mileage

As for the valve seals they usually give u a puff of smoke at start up and when they warm up they reseal. U cannot remove the pistons w. the engine in the vehicle due to the access plugs for 3-4 cylinders are behind the flex plate/ pressure plate. Hope this helps
