Every weekend before a track weekend I have a punch list of items to work on to get the car ready.

The most important item this week was to adjust the oil pressure.

The pressure is adjusted using this nut and bolt.




On the GTM you will need to disconnect the pump from a the block because the adjustment on the ARE 4 stage pump is tucked into the motor mount.

All the lines remain connected so it's not a big deal. After stepping the pressure down two times I ran into a problem. Since I am screwing the adjuster out its getting longer.

The adjuster was hitting the motor mount. Oh man. An hour job just turned into a project.

Luckily believe it or not it's possible to get the motor mount out without even removing the headers. You just unbolt it from the block and frame and twist and turn it with the Pfadt lower section downward.

It took me a few minutes to get the right orientations but finally it came out. Almost like those metal ring puzzles when you get everything right they come apart easily.

After a few min with the carbide bit and die grinder I had cleared out a pocket for the adjustment screw.




Re installed everything and it all fit. Whew dodged a bullet.

I just need to adjust the toothed belt by moving the pump pulley 5/16ths of an inch back. That's when things went south.
