I was at lunch today for about an hour, my car was running the whole time, i get back to work and when i get parked i think i hear something knocking, i turned off the radio and heater and sure enough there was a knocking noise, i pushed on the gas pedal lightly and it seemed to knock faster. I then shut it off, checked the oil, color and level looked good. I went into work for about a half hour, then came back out to the car started it up, and it's as quite as can be. Has anyone else experienced this?

I just had the oil changed two months ago with 5w30 , It was a knocking noise, it wasn't the valves or injectors tapping. Thing i was thinking about, if it was serious like a rod or whatever, it shouldnt just quit knocking. I drove home last nite about 20 miles and back to work this morning with no noise, strange. i have 42,000 miles on it.

'04 xB here, 35K. I have a knocking noise too. It sounds like something is banging against something else in the engine bay. It only happens when my car is in drive with my foot on the brake. It also happens only in the winter. It disappears as soon as the temperature goes above 40F.
