So randomly the other day my wife called me and said the oil pressure on her lunch break tanked to 0 . When i got home i started it up and everything was fine, oil pressure was between 40-60 ( engine was warm still).
The next morning i cranked it up and the oil pressure gauge was jumping all over the place between 20 psi and 40 just kind of twitching back and forth , i could hear a slight tapping of a lifter and the engine sounds rough , i pressed the gas and the gauge jumped up a bit to more normal psi, i took my foot off of the gas and it kind of dwindled down to maybe 20 , pressed the gas back up to normal, the engine no longer sounded rough, took it off and kept it off and it went down to 10 then 5 then 0 and my low oil pressure warning light came on, i turned it off and left it off for a min , turned it back on and drove it down the road, since i kept my foot on the gas the pressure was around 40 the tapping of the lifter went away, it got up to normal operating temp and the oil pressure was just fine even at idle. It seems to be only when it hasn't warmed up it's got the low oil issue. I don't believe it's just the gauge because of the tapping and also when it dips down from like 20 and below i can hear what sounds like a power decrease in the engine if that makes sense?
Should i just go ahead and replace my oil pump first, try a new sending unit, or drop the pan and check the pickup screen ? I kind of want to get this figured out today but have an 8 month old with me so it should be interesting.
oh my truck has like 215k miles and the oil level was normal. Thanks Everyone!
