2015 Silverado 4.3L v6 WT 120,000 mi. PO had a code indicating oil pressure switch, which was leaking, and had one in the truck. Upon replacement mechanic says p06dd is now showing. Oil change at the same time as replacement. Truck indicates oil pressure. Cold idle 60, warm drops to 40 at idle, under 40 in park, 50 underway as high as 70 under acceleration. 2 mechanics say not to worry as there is good pressure. Is the solenoid something to worry about in the v6? -
Anyone replaced their oil pump with a mellings pump and if so did you use the basic M295 model or did you go hi volume

I've got a 2005 Z71 4X4 ext.cab 5.3 Sierra, and I have been having an issue with oil pressure readings on the gauge. When I first noticed it, the gauge was at 0 kpa, so I pulled over and checked the level, which was at the top on the stick. Got back in and started it up , and the gauge registered 250 kpa, so I hoped slamming the hood closed fixed the problem. Nope. Went about 500 yards and the gauge dropped back to 0. Back under the hood and did the roadside fiddle-with-wires fix, and sure enough, back to 250 kpa. The trip back home was probably 10 miles, and in that time the pressure dropped to 100, then 175, then 60, then 0. This seems to be the pattern for the most part, depending on the interval from start to stop to start again. Anything over about 20 to 30 minutes,and I don't get the start up 250 kpa.....unless it is a real cold start. The wire wiggle test and connections all seem to be good and clean. And I have to assume the gauge in the instrument cluster is good seeing as it does register pressure at times. There has never been any top end noise associated, so if it is pump related, there must still be oil movement. The engine temp holds steady at running temp as well. My question would be...which direction should I be going? Oil pump? Sender? Gauge? Any help would be appreciated. Thanks, Steve
