G'day guys, I have done some research through the threads here but I am still unsure about a few things with my typhoon.
Recently the head gasket gave way, that's when I found out my turbo (Precision Turbo 6766) had developed pretty big shaft play, to the point of replacement, replaced with a Precision Turbo 6466 ball bearing gen 2, my worries is my oil pressure, cold its 50-55psi at idle, and warm at idle I have seen it dip to 10psi, my engine was completely rebuilt in 2015 and I noticed my oil pressure dropped but at warm idle was always above 20psi.
I run an earls inline filter and braided line that came with my old turbo from Golebys, my thoughts are either the oil pump is on its way out or am I missing a restrictor for the oil feel line.
Any advice would be much appreciated
