    Pickup tube question on 2007 GMC Yukon Denali 6.2

    So I have the common dreaded low oil pressure. I replaced the pickup tube ring and still have low oil pressure so I'm about to tackle the oil pump. Does the pickup tube mount directly to the oil pump? Asking because I would like to see and feel the fitment again of that O ring. I have seen...

    Question about oil pressure 2014 Tahoe.

    About a year ago I was getting low oil pressure. Maybe 17-18 when warmed up and idling in park. Changed oil and filter and it went up and I didn’t think of it after that. Now I have taken it on some road trips. I use the AFM disabler as well. I was at a stop light and had my foot on the brake...

    So this isn’t good, right?

    Crawling around for the first real time under the Yuke just now and found a LOT of fluid. Oil level is perfect. Haven’t checked trans yet.

    Can’t tell if my oil to full. Seems to go past the hashmarks. No symptoms of to-full oil though

    Low oil? ‘14 Tahoe 166k

    Does my oil look low? It seems to reach the 4th whole and stops. I was on maybe a 2-4° grade/slope in my driveway. I’m also concerned cause there’s a whole lawsuit for excessive oil consumption in these models. I’m about close to 2k since my last oil change

    Hey guys I got a 2005 LS Tahoe 5.3, the oil was changed I’d say close to a month ago and I remember looking under it and saw a little oil droplet just where the drain plug was about a week later after I changed it.

    2011 Tahoe White/Blue Smoke on Startup, Dealer Says New Engine

    Noticed within the past few weeks when we would start the truck cold in the garage, we'd get a puff of white smoke, minor blue hue, but very white. It billows for about 10-15 seconds, then goes away. The truck runs perfectly fine. No temperature issues or overheating. I performed a combustion...

    Yukon oil leak near back of oil pan

    Hello. I was doing an oil change today on my 2008 Yukon XL Denali AWD and noticed oil around the oil pan. I wiped everything down and ran the engine for a few minutes. The oil collects around the bolt marked with the red circle in the photos. I noticed the oil pan bolts were a little loose so...

    Oil not showing full on dipstick until 9 qts. were put in

They gave me the car back and were asking me if I had the 5.3 in it and if I had an aftermarket oil pan or something. I told...
