oil squirters

[effvee]

Good morning, from what I have read, it's a must if you use aluminum cylinders and having them coated. I believe(.003) is the piston to wall clearance, its supposed to help with the piston heat expansion. And using the Porsche squirters keeps 28lbs oil pressure in the system. My question was on how machine shops locate them in a type IV case, is there abetter position on the mains.
