    Yet another Yukon with engine tick and low oil pressure

    I will. Besides the low oil pressure thing, it’s an amazing vehicle and I enjoy every single ride.

    Yet another Yukon with engine tick and low oil pressure

    Just checking in. I’ve had the Yukon for a year now. Still my daily driver and nothing has changed tick/knock, oil pressure wise. I have put 8000 miles on it, since I got it. I hope to get a lot more (knock on wood). Never got the oil analysis done, prices were steep. Took it on a road trip...

    Yet another Yukon with engine tick and low oil pressure

    I promise when this gets figured out I will update with the solution. However I might begin to look for a used engine which could get shipped from the States. Better find some options

    Yet another Yukon with engine tick and low oil pressure

    Thanks for the input, appreciate it. Yeah it seems like oil analysis is the way to go, didn’t have to time to call them today, got off from work to late. It will probably give me an answer, so far I have probably just been trying to convince myself that it was not that bad since the engine 110k...

    Yet another Yukon with engine tick and low oil pressure

    Took a look at the oil dipstick today. It looks like I have metal shavings on the tip of it and the oil also has small black spots. Will reach out to oil analysis company on Monday and see if they can help.

    Yet another Yukon with engine tick and low oil pressure

    Thanks for looking up the specs, really appreciate it! Well I’m at 8-9 psi at 600 rpm in drive, driving around 70mph oil pressure sits at 38-40 psi - from the minimum oil specs you provided I’m within range. Yeah might as well have the sensor changed when the oil pump is going to be changed...

    Yet another Yukon with engine tick and low oil pressure

    From what I have read the 08’s don’t have AFM, which I was told that usually they don’t have as much lifter trouble as the ones who have AFM. I thought it could be pressure sensor, but since it’s pretty good pressure at start up don’t think that’s the culprit. And still makes the knock/tick/tap...

    Yet another Yukon with engine tick and low oil pressure

    Thank you for your input. I can’t tell if it’s knocking or not, it sure is making noise at start up but it gets less noticeable after a couple of minutes once the engine is hot. After it gets warm I don’t hear anything driving, only at idle. The shop actually talked about trying another weight...

    Thanks for sharing, it sounds like I should start saving for the high volume pump then and have that replaced

    I completely agree with you doing the repairs yourself is the way to go, then you know for sure what has been done.

    Yet another Yukon with engine tick and low oil pressure

    I do trust the shop, but I can always ask them what color the one they removed was and what the one they put in was, or maybe get the part number

    Yet another Yukon with engine tick and low oil pressure

    Thanks, it really sucks but it’s a car and nothing life threathing - that’s how I decided to look at it. The shop has a specialty in US cars - that’s what they work on - but there’s always a chance that they used the wrong o-ring I guess. The Yukon has travelled a bit: -early life North...

    I think you’re right there’s different colors and sizes for the o ring, I don’t know which one they used but I have to believe they went with the right one

    Yet another Yukon with engine tick and low oil pressure

    Yeah it could be related to the filter maybe the 3 psi difference, I’m using my scan tool to measure it. Just don’t like that it’s now closer to the 6 psi. O-ring was not the fix in my case, I might have to plan for a high performance oil pump - also beginning to think that maybe the engine is...

    Yet another Yukon with engine tick and low oil pressure

    They said that the o-ring was flat and hard. Didn’t mention anything about pick-up screen, I think they only changed the o-ring. They did put on a new oil pan gasket, 5w30 oil and AC Delco oil filter. At this point I can’t find a reasonable explanation for having a worn out o ring replaced and...

    Yet another Yukon with engine tick and low oil pressure

    Update. Got the Yukon back after the o-ring replacement. Oil pressure is worse now than before the change. Before the change it was 11 psi at hot idle, now it’s 8 psi. Oil and filter was also changed so everything should be new. However I never thought that the pressure would get worse after...

    Yet another Yukon with engine tick and low oil pressure

    Not really, unfortunately. I couldn’t find the ‘extractor’ so I decided that I would have the shop replace the o-ring. They will be replacing the o-ring mid April. Symptoms still the same. However, as temperatures haven risen since it’s spring, the ticking/knocking gets quiet way faster than...

    Yet another Yukon with engine tick and low oil pressure

    No I haven’t done the 2 extra qts yet, I’ll need that extractor pump so I can get the extra qts out again. This was just out of curiosity as to what oil pressure was when engine was warm and at idle as I bought the scanner and wanted to test it. But when I do the extra qts and nose down, I will...

    Yet another Yukon with engine tick and low oil pressure

    Thanks again everyone. That pump extractor looks great, I will get one, thanks. I bought a scanner and hooked it up when the engine was warm and at idle, oil pressure fluctuated around 11.9 and 13.9 - so it is lower than what I’d like to see.

    If I overfill it, I will need to drain the oil and put in new oil and filter right? The overfilling is just to check?

    Yet another Yukon with engine tick and low oil pressure

    Thank you again everyone for sharing your knowledge/input, much appreciated! Seems like I need to have the shop look into that o-ring, already spent a substantial amount of money at the mechanic thus far, but seems like it will need a lot more work. I did try the trick of parking the car on a...

    Yet another Yukon with engine tick and low oil pressure

    I was also pretty confident that I would like to have it replaced, but since mechanic said that oil pressure was normal at idle he said that I probably shouldn’t be concerned about the o-ring. I’m not sure how involved dropping the oil pan is. In the YouTube videos it seems like a job that...

    Yet another Yukon with engine tick and low oil pressure

    Thank you for your input, it’s nice to hear other seeing similar readings. the mechanic also said that the oil pressure was normal and within spec even though the gauge shows oil pressure at idle a bit on the lower side
