Well the leak is at the heater pipe. The intake had a bit of dripping oil in the runners but the CCV was replaced not too long ago. I scoped a couple cylinders and they were normal looking, a bit of flaking carbon on the pistons.

Compression test results:
1: 182 psi
2: <30 psi
3: 180 psi
4: <30 psi
5: 180 psi
6: 168 psi

From sticking my crappy bore scope down there I can’t tell anything obviously wrong with pistons 2 and 4.
