Engine Mechanical problem
1998 Honda City Front Wheel Drive Manual 194000 miles

Recently my engine came to upper heat limit due to a leak in the radiator, which I repaired after that. Now no leaks, water levels remain unchanged in the radiator tank. I want to know whether is there in effect to the engine oil (mobil 1000 15W40-about 2000km run) due to this heating, if so how to check. I am about to go for the emission check which is required for car licensing and do not want have any trouble due to above issue.
