Just finished a tune on the GTP. AC Delco wires, Autolite 606 plugs, and O2 Sensor. Didn't have to rock the engine to change out #6 plug due to changing out the O2 sensor. If I were to change plugs without changing the sensor, I'd remove it to access #6 instead of rocking the engine. Lot less work pulling the sensor than rocking the block. It was a bigger pita removing #2 plug wire than anything else. Have a new PCV valve to swap out, but I can't find out where it's located. Need a little help in locating where the bugger is actually ay. Thanks in advance, Gary.

Remove the 2 10mm bolts, you may have to pry the cover off, but becareful, it's got a spring inside it. Remove the spring, I had to use a pair of needle nose pliers to get the PCV out.
I had to sand my old gasket off with a sanding wheel and drill.

Thanks a ton Austin. Congrats to the Longhorns by the way. I do have to say, neither USC or Texas has much of a defense to speak of.
