    Ready to Junk it; 2007 Yukon 5.3 EVAP

    I totally feel your pain. Except mine, I'm the original owner, so I've had lots of good years to offset the recent frustration I've had. Believe me, I know exactly how you feel rn. If it makes you feel any better to hear someone else's pain, I had a valve spring break, got it towed back to my...

    Ready to Junk it; 2007 Yukon 5.3 EVAP

    No kidding! I spend two days clearing the line between purge valve and the front of the fuel tank. Soaked it in B12, blew back and forth, back and forth, once clear, then changed canister, vent valve, purge valve, dropped the tank and blew every line out on that end of the system. And even then...

    Ready to Junk it; 2007 Yukon 5.3 EVAP

    Then you are good! You are probably seeing the "archive" code, which means it's not an active code. Mine is the same way after I cleared the lines. I can see that the code once active, but is no longer active. If the code comes back then you will need to do a smoke test like someone mentioned...

    Evap system o-rings

    It's missing, that's the problem. Apparently I must have blown it out when I was clearing all that stupid charcoal out of the line. GM charges $450 for that mess of hoses. Normally I would do exactly that, except via Rockauto. Even there the price is so much more than if I can just find an...

    Evap system o-rings

    Sorry, I really thought anything that used that particular connector only had one style for this generation so I didn't realize there might be version differences by year. This is on a 2012 Suburban, and there's two places this exact connector is used. One of those is the long evap line that...

    Evap system o-rings

    Does anyone know either what size or if there is an aftermarket o-ring replacement for this particular evap connector? Edit: To remove the confusion here at the top of the thread, I'm adding a graphic of the correct connector, i.e. the one with the slide locking tab. Note, the "cheap drawing"...

    It's a sign that your oil is aerating.

    Oil pickup tube o-ring replacement

    I have a separate question if anyone is reading this thread still. I have a friend I was telling the story to and he was "that happened to me too!" but he never solved it. It happened while on vacation, Tahoe loaded down with gear, driving in the mountains. No bubbles on the dipstick, just no...

    Oil pickup tube o-ring replacement

    How hard? Technically none of it was really that hard. However, it was a dirty and nasty job, and uncomfortable working on my back under the car. There is lots of opportunity to mess up too. Scraping the mating surfaces of the pan and engine block took a lot of careful work so as not to scratch...

    Few things I wonder about.

    I have a 2012 Suburban which has the "upgraded" rocker cover. I also have a rear main seal leak, so maybe not a connection there. I also note that even with the upgraded rocker design, I had oil in my intake manifold, so it doesn't stop the issue entirely. I put a catch can on it recently.

    Oil pickup tube o-ring replacement

    Seems like changing the o-ring is what fixed my problem. Mine was pretty flat and wider on one side, and a little less flat but still clearly not round around the rest of it. I will repeat what my mechanic said when I called him to see if I should tow it to him or was it something I could fix...

    Perfect! Sorry I should have included my vehicle info, but you nailed it. And I never would have found that page.

    Oil pickup tube o-ring replacement

    Does anyone know the correct torque spec on the secondary oil pressure relief valve. I can't find it on Charm and I don't fully trust Google search results. I see some saying 22 ft lbs. I think that comes from the listing on michiganmotorsports.com. Charm tends to have names for parts that...

    Oil pickup tube o-ring replacement

    I did change the oil pressure sender first. No change in behavior. As I understand one of the failure modes with the o-ring is that if it loses seal, the oil pump pulls air with oil, which cavitates the oil, leading to losing pressure gradually. That's why you can see bubbles in the oil on the...

    Oil pickup tube o-ring replacement

    Thanks for all the helpful info. Mine is a 2012 for reference. I think the oil pump is good, because the symptom was at start pressure seemed fine, then dropped as I drove. My mechanic told me about the dip stick test where you look for bubbles on the dipstick, and sure enough that's exactly...
