I did a full engine rebuild in the past few days. Got everything together and in the car. Lindsey told me I should use a new oil cooler because I will never get all the metal out of the cooler. I was installing the new cooler when I was getting the OPRV in, I noticed some threads were damage since it didn't want to thread by hand. The threads are still very intact and only 1 spot is a little damage and I figure running a tap through it would clean them up. Does anyone know the size/thread pitch.

Thanks,
