Wrong.
It could be, and usually is something as simple as the coilpack gaskets that go under the valve cover. Inspect those before you start worrying about piston ring or valve seal failure.

Wrong again.
First find out where the dent is, then make a judgement. My pan had a big dent in it. But it was in the side and would not have affected the oil pickup at all. Regardless, we banged it out and all was good. However, the slightest dent in the bottom is bad news and MUST be replaced or banged out if possible.
