i have a 01 eclipse gs, with the 4g64 2.4L I4 cylender, and i have a clogged oil pump so everytime i rev under 1000 the light goes on, now instead of replacing the whole engine, my friend has a 4g63 head with internals i can use, and i would jus need to buy waterpump, oil pump, and timing belt and maybe crank bearings.... anyone have any ideas on an easier way to do it? and if the 4g63 head with fit on my block??
