DIY: Oil Pressure Gauge

spearfish25 · 11-08-2012, 09:59 AM

Interesting update. Haven't changed anything but now my oil pressures are running lower. When fully warmed up I'm idling at about 8psi, hit about 30-35psi at 2k RPM, and get to a max of about 60-75psi under WOT. Not sure what made the change. Thoughts? Some sort of blockage before the pressure sensor (not sure how that would happen). If there was blockage in the oil cooler, I'd guess the pressures would register higher, not lower.

Same oil used as before?

Pressures below 3k rpms are about half of what you had before. Anyone know if the design of the oil pump would be such that it can partially fail and reduce oil pressure without a complete failure?
