    Very common issue with the 5.3L. mine has 332K Miles and after an oil change I will sit at 40 psi at cold idle. When warmed up, it'll sit at 30 psi hot idle. The gauge is deceiving. It'll look like it's 20 psi because it's about halfway to 40 but it's actually over 30 psi. As the oil gets several thousand miles, the pressure will drop significantly due to it bypassing from a heavily soiled filter. There's actually a tab for low pressure due to people changing the oil without changing the oil filter.

  2. Avataaar/Circle Created with python_avatars Andrew Roman says:

    These early LS motors were notorious for weird low oil pressure complaints. You could also have an internal oil leak. The cam plate is a common one especially with high mileage units. The oil pumps are also pretty crap.

  3. Avataaar/Circle Created with python_avatars cymaz100 says:

    Any advantage in doing an engine wash before adding new oil and filter?

  4. Avataaar/Circle Created with python_avatars PlagueSD says:

    Storing oil in a coffee cup. How much you wanna bet someone is going to get a surprise tomorrow morning when they go to take a sip of their "coffee".. LOL

  5. Avataaar/Circle Created with python_avatars John me says:

    Thank you for an important reminder Ray. A very sad and similar thing happened to a dear friend's sister. The child lived but it crushed his pelvis.

  6. Avataaar/Circle Created with python_avatars Anthony Young says:

    My 4.3 has got better oil pressure than that it runs at 50psi and it's got over 200.000 miles on it.

  7. Avataaar/Circle Created with python_avatars Brad says:

    You need those sheets of paper to put on the floor of the cars.

  8. Avataaar/Circle Created with python_avatars Chris Stephens says:

    Did you torque wheel lugs?

  9. Avataaar/Circle Created with python_avatars Ivan Bradley says:

    HEY ALL YOU GUYS!!! haha

  10. Avataaar/Circle Created with python_avatars Jeff Long says:

    Not long after I met my wife, we got tickets to a Scandal/John Waite concert. (I know, I know! Who the hello is that?! Scandal was Patti Smyth singing "The Warrior and John Waite was with The Baby's in the 70's and went solo in the 80's and hit the charts with "Missing You" in '84). Anyways heh, she insisted we take her 76 Plymouth Duster. Sucker had a steering wheel the size of a NY city transit bus heh. We got a flat on the way so as I'm getting everything out to change the tire she says, " Can I change the tire?" She says, "I know what's involved but I've never done it before and I want to know I can if I'm ever somewhere without help." Torn I was lol. Let a girl change her own flat?! "Sure!" I says. "Just ask any questions you might have. And damned if she didn't change it right there on the side of the road. She wasn't petite but she wasn't far from it. I think I knew right then that I lucked into something special. And I was right.

  11. Avataaar/Circle Created with python_avatars Squash Jones says:

    Get the filter apart take about 10 folds in a rag and squeeze it in the vise.
    Run a magnet across it.

  12. Avataaar/Circle Created with python_avatars NackDSP says:

    Nothing better than this on TV on a Saturday night. Thanks again Ray!

  13. Avataaar/Circle Created with python_avatars David Thatcher says:

    Need to run some BG EPR in there.

  14. Avataaar/Circle Created with python_avatars Jack Jacke says:

    No no! Not my dear! She is wife unit! Get it right!

  15. Avataaar/Circle Created with python_avatars Paladin of Peace says:

    I have a new found like for this channel after seeing his kids and now his wife in the shop with him. Ray has a cool little wifey. Good video 😀😉

  16. Avataaar/Circle Created with python_avatars leakyjeep5.9 says:

    How do you find this shop?

  17. Avataaar/Circle Created with python_avatars DasRenegade says:

    damn thats some low ass miles for a 2004

  18. Avataaar/Circle Created with python_avatars The Direct Dasher says:

    When customers from other locations respect the work you did so much they come directly to you for any other work. That's mad respect.

  19. Avataaar/Circle Created with python_avatars Phill McKrakin says:

    I never understood why folks don't use oem filters. If you buy a dozen from Rockauto they are like $3. each. You can't buy a cheap off brand for that.
    Throw that K&N filter in the trash asap!
    That Suburban is clean. With those low miles I would have a hard time believing there was an oil pressure issue. My 05' had 260k and had great oil pressure. But I used oem filters and changed it every 3-4k miles. I ran it hard, towards the 260k mark she was using 2 qts between oil changes.

  20. Avataaar/Circle Created with python_avatars Ghetto Wagon says:

    The Oil pump pickup tube O ring probably is shot on it. I had this on a 06 5.3. Tapped bad. Now its been ok for about 40k miles Only 113k wow

  21. Avataaar/Circle Created with python_avatars K Campbell says:

    Always a good honest mechanic, hard to find….oB

  22. Avataaar/Circle Created with python_avatars Markus Williams says:

    “NO MORE SCOLDING OIL…” Then the oil said “watch this” lol

  23. Avataaar/Circle Created with python_avatars qwaszxpolkmncvb says:

    Friend did a oil change two days ago. Forgot to put the plug back. Been doing this stuff for 30 years and there's still a first time for anything. Lol

  24. Avataaar/Circle Created with python_avatars Robert Racer says:

    Good stuff.

  25. Avataaar/Circle Created with python_avatars F Huber says:

    That oil seemed awefully thin even for hot oil

  26. Avataaar/Circle Created with python_avatars Ian Mcleod says:

    Another great video from the Rainman Ray.

  27. Avataaar/Circle Created with python_avatars ezra myrick says:

    Hey Ray. My 88 dodge w150 lost oil pressure once because the oil pump pickup was clogged with gunk. Thanks .love the videos

  28. Avataaar/Circle Created with python_avatars David Wellman says:

    Hey Sloth… (Goonies reference, I love it)

  29. Avataaar/Circle Created with python_avatars Christopher Cormier says:

    On my Silverado I use a screwdriver to puncture a hole in the bottom of the oil filter. Less mess.

  30. Avataaar/Circle Created with python_avatars Philip Wilson says:

    2 comments:- 1 in U.K. when we refer to the wife we say the BOSS. / 2 maybe the owner of sed car was so impressed with the hard work done last time they tracked you down to get an honest job done instead of going to another greedy company

  31. Avataaar/Circle Created with python_avatars Michael Mark says:

    Over its life this vehicle has adveraged 26.2 miles per hour.

  32. Avataaar/Circle Created with python_avatars Metal Mike says:

    Warning your new red oil drain is going to make it Rain Motor Oil in your new shop if you go to empty it Great videos Ray

  33. Avataaar/Circle Created with python_avatars Crisis 1837 says:

    Would love a follow up on this…I have an 08 suburban that had no oil pressure light…changed oil…changed sensor….8 months later the warning is back…only comes after about 30 min of driving. Still about 1000 miles till oil change due. Not daily driver.

  34. Avataaar/Circle Created with python_avatars Frank Baber says:

    I like your story on kid safety, I too have a similar story!

  35. Avataaar/Circle Created with python_avatars FAST EDDIE says:

    Man that’s a lot of hours for the miles it has. My work truck has 4900 hours roughly and has 219,000 miles not to mention it has a PTO that gets used quite often.

  36. Avataaar/Circle Created with python_avatars Mitch Carlisle says:

    ……..and people wonder why they have low oil pressure? Use thicker oil folks!!

  37. Avataaar/Circle Created with python_avatars Ceanothus says:

    Read the label on that brake cleaner. Cancer, it's real. Wear gloves.

  38. Avataaar/Circle Created with python_avatars Stephen Jaggers says:

    Does it have 2 batteries in it???

  39. Avataaar/Circle Created with python_avatars turbora40 says:

    Hope you sacked the employee who made that mess on your floor!
