yesterday, when I was running under the car, I noticed that when you're with the booze right under the oil pan there's a distinct hum. If you almost touch the oil pan with your hand from the bottom, you can feel quite strong vibrations (feeling only at the bottom of the oil pan).
Is that normal, questionable or even bad?
Oil pump that's nipping? I just wanted to ask what your opinion was. Idea of these symptoms.
Greetings.
