[Shotimes] What can destroy a cat?

[cmichaelo@optonline.net]

I've been using the K&N filter that came with the ShoShop 80mm MAF for about 50k miles. I cleaned it every year. It does have a few "dings", but no open tears. Some other possibility for direct air to enter the manifold is at the throttle body where the rubber tube connects. The tube was definately too big for the TB, but by tightening it hard with the metal ring clamp it stayed in place.  But frankly I never felt confident that it made air tight contact to the TB. (Btw, this is the tube that ShoShop supplied the tube.)  For the last 5k miles I've been using the ProFlow 77mm MAF, and everything is tight with this setup.

One more things I should let you know is that my oil consumption got suddenly worse around 90k, going from 3500 miles/gl to 1000miles/gl. This change happened at the same time I switched from Amsoil 10W30 to Amsoil 0W30. (I've been using 10W30 since 27k.) I kept using Amsoil 0W30 until 100k, then switched back to 10W30. Oil consumption, however, remained at 1000 miles/gl.
