can anyone tell me what I need to do to diagnose my low oil pressure problem
the relief valve is moving freely and I'm just about to change the spring but I don't think it's that, there are no visible leaks around the sandwich plate or anywhere else, I have done a full overnight oil change and none of it has made a difference, I'm just about to check the pickup pipe, but I find that unlikely since I had the sump off in March and it was clear then.
if anyone can shed light or tell me what to check to diagnose this once and for all before I pay stoopid money for a pump, I'd appreciate it.
supposed to be: 4.5bar on cold idle
rising to 5 bar when revved
1.5bar on warm idle.
is currently: 2.5bar on cold idle
rising to 3 bar when revved, and 3psi on warm idle
Thanks in advance
