is it possible to have too high of oil pressure in the oil feed line on a turbo that it's blowing oil past the seals in it ?

oil pressure from the back of the block is pretty constant than anywhere else on the block. Since the pressure are pretty constant, it depends on the line, I sell -3AN for all my customers and never had any problem. Same goes for my personal car and race car

To be honest I don't even know what the size of the line is. I'm pretty sure it is -3AN. It's definately no bigger than that...cuz I have -4AN going to my oil psi gauge and it's bigger than my turbo feed line. I know I purchased them from someone on here, and I can't even remember who it was!

I just checked my invoice history, you purchased it from me. YOu have a -3AN feed line
