Low oil pressure on cold starts?
Hello y'all!
I'm having some issues with low oil pressure/oil pressure light illuminating on cold starts. The car won't immediately build oil pressure, and the light will remain on for 5 or so seconds, followed by a light ticking sound that is audible until the light goes out, presumably knock. This first occured a few years ago, when I first installed my turbo kit + oil cooler, and chalked it up to the more viscous 5W-30. This was reinforced when I switched to 0W-30, and my oil pressure issue went away.
However, I recently did an oil change and the problem came back. Same Mobil 1 0W30 and OE Tokyo Roki filter, and triple checked oil levels. My theory is air trapped in the filter, or potentially cavitation? I would definitely appreciate some input on this one!
Thanks in Advance!
