Hello everyone, i'm asking for advice & help you guys. I know it's not a good way to start with asking help, I'm sorry bout this. Let me shortly introduce myself - my name is Alex, I live in Russian Federation, Moscow and I drive 2006 Chevy Tahoe (gmt 800) with 5.3 Vortec engine (simple gas, no flex fuel). I am facing a problem with my oil pressure gauge - while driving or at idle oil pressure gauge jumping from 0 to max value. It may stuck at 0 for long time (hour or so) or can stuck at max value also. When I switch ignition on gauge does NOT jump to max, everything seems to be ok for at engine start but soon gauge become messy. As a pressure falls to 0 I have an alarm warning with horn and alarm in message centre. When this happenes, gauge jumps to max and when falls down again sometimes. I'd like to mention that there are not any strange sounds with engine (no knocking or something) when pressure falls down. Since I did not find a particular my problem at different forums, I decided to ask you guys. Also it's a bit difficult to maintain and service such vehicle here in Russia, so I would really appreciate for any advice of community. I recorded some videos with mess going on with my vehicle and uploaded them to YouTube so I can share them with you. https://www.youtube.com/watch?v=RbPpOAKi2D8 https://www.youtube.com/watch?v=Lbm4Gn3YYzI I found in rockauto store this new acdelco oil pressure sensor ACDELCO 12677836 - is this correct partnumber for me? Any advice and help truly appreciatable. P.S.: thats my second GM truck, the previous one was Tahoe 1996 5 doors 5.7 Vortec engine

New to the forum here, and I have a 2005 chevy silverado 1500 with the 5.3L. I drive to and from michigan from chicago for college every couple of weeks. The last time I drove up to michigan 2 hours into my drive the oil pressure gauge started slowly moving down from 40psi. Every 10 minutes it seemed it moved down a notch until it got to 15psi and then I pulled over just to investigate because the truck was running perfectly normal and no warning lights or anything were on. I did a walk around, no leaks, no engine noise and the oil level was in the same place as when I left. Also when I stopped the pressure gauge dropped to 0 at idle and the truck idled normal. I continued to drive till i got to my destinations 30 minutes later. The next day when I started it back up the oil pressure is now reading normal and has read normal for the last week. I went to tech school and I know my way around an engine and i'm almost positive this isn't a mechanical issue, im thinking its the oil pressure sensor or sending unit or it could be the gauge itself because first gen silverados are famous for bad gauges but i feel if it was a bad sensor there would be warning lights? Not sure though, any of you guys experience an issue like this or have any idea of what to check or what it could be?? Much appreciated!!
