Sounds like the engine is running loud
a loud engine can mean a lot of things, could be worn valves piston rings etc, I myself have round the clock engine and it was noisy, but i used a can of engine restorer, and noticed with in ten minutes the difference, its expensive but on an old warn engine it had done the trick. might even help yours, it does not really matter how meany oil changes you do an engine will wear a bit, if its pulling ok with no difference then its not a really serious problem, it could just be a blowing exhaust manifold or downpipe, or even a damaged air filter. check these parts look for cracks in the manifold as these when the engine gets hot will expand, even just a tinny crack can make a loud noise. check the the manifold seal to the engine is good, good way to test the seal is water in a squeezer bottle or spray, or even just look for blow marks on the engine. also check the engine oil cap, check it for a mayo looking oil color this can be a sign that the oil is getting damp or water is getting into the oil. this can also change the sound of the engine as the oil has become contaminated, oil can have a bit of water in there but its usually heated away with engine use. i hope this items help you find your problem.
