    Seeping coolant hose

    How difficult is it to change the oil coolant lines myself? My Tahoe is a 2011 4x4 with Z71 package. I see things about this being more difficult on 4x4 compared to 2wd models. Any good guide or videos on this?

    Seeping coolant hose

    So that’s an oil line, not coolant? I just had an issue with low oil after never having an issue for years. See my other thread where I had low oil pressure due to low oil level. https://www.tahoeyukonforum.com/threads/2011-tahoe-white-blue-smoke-on-startup-dealer-says-new-engine.124852/page-2

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

    Thank you everyone for the help. Added an AFM disabler last week and changed the valve cover today. She’s running great. Will watch the oil from here on out.

    Seeping coolant hose

    Have a coolant hose that appears to be seeping fluid slowly. See attached image which is looking down just behind radiator, in front of engine. You can see the fluid on the hose. Doesn’t leak much but I add a small amount of coolant every 6 months or so. 2011 Tahoe 5.3l Which hose is this? Is...

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

    UPDATE AGAIN Spoke to the Dealer service manager, told them I was disgusted with their lack of diagnosis and the service manager actually agreed. The service manager said the technician who claimed I needed an engine replacement basically did nothing to diagnose the issue, just looked at...

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

    The rings are free, engine is running just fine. The issue is how I ended up with the oil loss which I suspect is related to the valve cover and/or AFM problems.

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

    Mine was built in October 2010, I checked the driver door sticker (10/10). I doubt it has these upgrades, it falls specifically into the model date range where this is an issue and the TSB description sounds textbook as to what's happening. I suspect that simply due to age, some things are...

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

    Is there some specific way to check the existing one? I have ordered the replacement driver side valve cover and intend to replace the existing one myself and then monitor the oil levels.

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

    UPDATE SINCE ORIGINAL POST: Dealer performed oil change on Sunday (1/14) before they started diagnosing the problem so at least it's now full. Brought it home yesterday, sat overnight in cold garage, started this morning, and ZERO smoke. Nothing, nada, zilch. Could it simply be low oil level...

    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...
