I was digging in to do the leak down test this afternoon and I think I found where the oil on #2 and #4 are coming from. There was a c-shaped piece of valve stem seal sitting by the valve spring on #4 and it's pretty clear that seal is trashed. The #2 intake seal is in worse condition.
It's kind of a pain, but I'm comfortable doing seal replacements in the car since I've done them on my '04. Does anyone know the size I should look for?
BTW, for you sharp-eyed viewers the black mark on the pushrod is left over Sharpie from when I broke in the engine to make sure they were spinning.
