Mine seems louder in the wheel well areas too. I hear it the most sitting at a drive thru ATM or Dunkin Donuts drive thru where you are right up against a brick wall. Here is mine:

Why would piston slap start all at once? Also, I have non-magnetic metal flakes in my oil, could that be from piston slap? I guess I dont have a good grasp on what piston slap is.

Thanks for the audio. That's the sound. Mine isn't quite as loud and is tonally a bit higher. It disappears for awhile after I rev it and IS a bit louder on short trips.
What exactly is it? Hydraulic lifter that gets intermittently clogged? Would 10-40 be better than 15-40? It's been very cold this winter in so cal and I'm thinking maybe the 15-40 is too thick. It never did this in the summer.

Keep in mind that our engines require a different type of motor oil than a "modern" engine with overhead cams and variable valve timing.

Stick with the 15w-40 year round and dont worry about the noise.

If you have metal pieces in your oil then it means your engine is falling apart, something is breaking into pieces. This could be old pieces from a previous failure and your engine was repaired but the oil pan was not cleaned out, or it could be a new failure and you are going to experience some or other event if you leave it.
