No, this is the place for technical discussion. We do it in public so assertions like mine and yours can be tested and challenged.

Most folks do have a problem envisioning air being drawn in an exhaust leak. It just ain't intuitive! But it happens, because unlike the steady positive pressure in a cleanroom, the engine exhaust is a series of pressure peaks in waves with intervening pressure lows, proven to be below atmospheric.

Do a bit of googling, and you'll find explanations, complete with oxygen sensor scope traces identifying the leaks. In my own experience, it doesn't take much of a leak at all - one that I can just smell and only hear with a stethoscope aimed at it.

If you lend someone $20 and never see that person again, it was probably worth it.
