I noticed that my oil pressure seemed low and I figured it was mostly the valve cover gaskets because I found oil on the threads of the spark plugs. So after the replacement pressure was setting at 20-15psi during warm up then 10psi at operating temp. Took it for a 15min drive pressure stayed at 35-30psi. As i was heading home I noticed pressure was slowly dropping and only increased with rpms, once i got home oil pressure was at 0 but still went up with rpms. The low oil pressure light only comes on during startup, im using 10w-30 w/ Nismo 15208-RN011 oil filter in my SR20DE, and I don’t see any damage on the oil pan or leaks around the engine. I would appreciate any thoughts on the subject!
