Brief background: BSE kit from ExtremePSI w/front bearings flipped. Lightly ported oil filter housing. Oil port mod done to the cylinder head. Small 16G fed from the head using a stock 1G line. Reconditioned/re-sized rods (ARP rod bolts), rod bearing clearances in spec (don't remember exactly what they were, maybe .002?). Cylinders honed, new NPR pistons and rings (which is why I'm using dino oil for the time being). I used Castrol Syntec 10W-40 before all of this and the low oil pressure idiot light never came on.
I've had two incidents of the low oil pressure light flickering at idle since I started driving the car again. The first time happened with Super Tech 10W-30 dino oil and Purolator 14610 filter. I dumped it out and re-filled it with Super Tech 10W-40 dino oil, but had it happen again yesterday. Interestingly enough, the temperature was above 70 both times it happened. If I blipped he throttle, the light went off but flickered at idle again. When the light came on, I didn't hear any knocking or collapsing lifters. When it's cold out, the light has never come on. The light coming on worries me, but at the same time it doesn't because I have an Autometer electrical oil pressure gauge (remote mounted sender) that shows the oil pressure at about 12 psi at idle (it's a tad below the line between 0 and 25). I know the stock gauge isn't very accurate, but at idle it's nowhere close to the bottom mark either. Once warmed up it's about 35psi at 2000rpm crusing on the street, maybe 50-60psi on the highway cruising at 65mph in 5th. The wire is still clipped to the idiot light sender, but has anyone ever had one of these go bad? Should I be genuinely concerned about the light, or just ignore it because everything else says the oil pressure is fine? Coolant temp is fine, both by the stock gauge and Autometer electrical water temp gauge.
