That can't be a 22RE. I didn't here a wristpin rattle!
I remember when I had my '89 XtraCab. I left a light and thought "Great , my wrist pin is getting louder." after it had been rattling for quite some time. I then was relieved to look over and see another Toy making all the noise.
I loved my '02 WRX with a Prodrive muffler. Definitely sounded more Porsche than rice.
