I had a lot of issues with oil pumps so it was kind of an inside joke to people that have read the build thread.
Basically I'm saying the pumps failed before I managed to stress the gasket
That's alittle low. ESP driving.
I'm a metric kid so I work the vast majority in that
15psi hot idle is ok, alittle low but mine has run lower than that before now. I take it your on a thin oil like a 30/40?
I run a 50 because I didn't like seeing 12psi on my gauge lol
Driving anything over 4K should be more like 80psi or 5.5bar.
The pressure relief should come in about 80psi and you'll see the gauge jump down afew psi.
