That'* because I'm the one that works on it. My hands and arms really didn't get that dirty. I hate dirty engine compartments.
He just texted me, he got tranny fluid on his lips and they went numb. I'm not sure I want to know what he was doing sucking on a tranny.

This is how we move faster, don't you find it funny when someone is still leary or antsy around the air tools?
LOL, I use a favorite 10mm 1/4" drive that I use. 3/8" and 10mm are cousins.

You know full well where that gasket comes from Bill. The same guys that can't drill a PCV hole threw the IC core in the right place, or count past 2.

Oh, i know Dan. I'm trying to not bash them etc. I'm saying for other members. I make all my own gaskets when intercooling because of the benefits and cost.
