It just happened one day, when it was really cold. I used to park it in my garage at home every night, and now I leave it in the school parking lot in Humboldt, since I live on campus. Sometime during the beginning of winter it just happened and it scared the out of me. So I turned it off right away and checked under the hood, I thought a cat or a rat climbed up inside and got shredded in the belt or something lol.
Also, I've been driving it the last couple days and it only lasts a few seconds now. The weather is warmer, but I've also been driving fairly regularly.
When you say 'really cold', what do you mean? 60*? 20*? -20*?
When was the last time you changed your oil?
What weight of oil are you using?
What does your oil pressure gauge read on startup? @ 60mph? At idle fully warmed up?
From the sounds of it could be, but the problem with that it goes away. With an exhaust leak it usually never goes away and gets louder the faster you go, but road noise can hide it.A friend thinks it's an exhaust leak, is that a possibility?

Could be a failed/collapsed/stuck lifter. If it doesn't pump up with oil pressure it will let the clearance between the pushrod and rocker arm be excessive and cause a lot of racket. It can a lot of times can go away when warm as everything heats up.
