It could be for any one of a dozen reasons bad rings scored cylinder walls bad head gasket leaky valves ETC. you should be able to figure out which it is thoght fairly easily head gaskets are very obvious as you get oil in the water or worst water in the oil. Any of the others a good mechanic can figure out.

The best way to find out would be to do a cylinder leakdown test to find out where the pressure is going, in the crank case, intake, or exhaust.
