Is it bad to rev a Toyota Scion 1NZ-FE Engine at 7000 RPM for about 6 times? I did let ho of the accelerator pedal once it hit 7K RPM. Yes, it does pop when I let go of the accelerator. There is no noise or knocking from the engine otherwise. No leaks. No nothing. Are my piston rings or anything like that damaged? (I believe it didnt knock because i over filled the oil a little)

And please… no jokes, sarcasim or anything like thay… i just need a direct answer. (I am chabging my 1nz anyway)
