If you are running with low oil pressure all the more running and testing that you are gonna do is destroying more in your engine/making problems worse.

I searched for a long time for my oil pressure problem and the above mechinical oil pressure sensor is the best to monitor oil pressure

Buy one and let us know what oil pressures are you running. Around 2000 rpm you should have 2.8bar according to the haynes manual. I ran about 1.8 there with foocked pump. If that is the problem at you i would suggest change oil pump and take a look at all bearings. If bearings are crap change them too

Else if you continue prepare to trow your new cam away too in a while!
