      I was wonder how many miles on the one changed out or was this a new truck? how about weight between old and new.. you hear a lot of folks on youtube talk about how heavy they are when changing them out.. great video with lots of good info.

      Yes but changing that filter did not restore power or reduce blow by like he said. It only allowed a little more to flow into the intake. I'm really surprised he don't know that.

      ​@@DavesAutoCenterCentervilletruck frames aren't straight. They don't stay straight, and many don't come straight from the factory. They handle like garbage. They need diagonal "spokes", just like a bicycle, except on the truck frame. Forming an "x". One inch bolt, near the rear cross members, should be fine. Build a mounting plate or backing plate, or hanger for it, and thread it through...... Then tune it just like you tune a bicycle wheel. You're welcome. I will call your shop to confirm on Tuesday. October 22. When you make a video about it, just say Sasquatch told you about it.
      Also, unibody vehicleS can have similar "x" installed and formed into the design of the floor, with bolts that can be tensioned to straighten out the frames....... They aren't perfect from the factory, and don't stay perfect. When you're on ice, the car MUST be straight.
      This should have happened 140 years ago with the invention of cars. It would be the first "safety" feature of a car. For some reason they are obscenely expensive, and they aren't even tuned for alignment and handling. It's obscene. Adjustable rear subframes don't counT, because at high speed, on ice, they weathercock - from different air drag across the warped body.

    A way we test blowby in tier4 emissions equipped engines is by disconnecting and blocking off the ccv system and installing the blowby gauge inline. This gives a more precise reading of blowby and a better indication of ring/cylinder wear if your looking to gauge it. I love the oil cap technique though. The reason those later model engines blowby went down may have been due to the ccv system opening up more and pulling that through

    Well Dave, your new blowby toy tells us that the rings have failed, this is very vital info, as ANY missfire will cause oil contamination by fuel and carbon particles, with only a few thou clearance on journals etc, it becomes obvious why engines sieze or run their bearings. You and Lake Speed are highlighting the real seriousness of oils, but also the point that lots of factors also play into this situation.

I didn't have a flow meter but you couldn't feel any at all and it wouldn't flap a sheet of paper either. When I sold it at 640k, it still had none. I changed the crankcase vent filter to make sure that wasn't skewing that... What a sweet truck, it ran like new and looked new except the cruise ctrl buttons.

    Testing blow by in inches of water with a manometer is standard practice in the heavy equipment/trucking industries. It’s always amazed me you guys never checked it with a measuring tool until now. Also looking at numbers is fun but it would be better if you specified in the video what units your measuring them in (Yes I noticed the gauge said CFM) & also what the permissible value or repair limit is for each engine. I believe a Cummins 6.7 (industrial application) is roughly 7 in/h20 with the proper orfice tube installed for testing.

    I had an old gas-powered van with a 302 . It had so much blowby that I installed a vent with a filter to catch the oil. I drove it until the timing set failed. Back then, you could buy a remanufactured engine for about $500. That's what I did. Drove it for a few more years. Everything else was extremely worn out by then . I expect that someone got a really good engine cheap.

      The medium used (mercury or water) doesn't define one or the other, they just give a different scale.
      The difference is which end of the fluid column the sensing line is connected to.

    You should let all your staff blow the meter. If there's any smokers between them, they'll get a shock if they see how weak their lung function is compared to non smokers. When my doctors did that test on me ,I immediately quit😅

What I do know is that I wondered about the true seriousness, for lack of a better word, about the blow by on my diesel truck in a more scientific approach with numbers to back up weather or not I should look into getting a rebuild done or wait.

    I have a rare V6 Powerstroke that had a clogged crank case breather. I did the same thing with a hose in the oil fill cap to let the pressure out until I figured out that a breather from a 6.0 Powerstroke would fit.

  • @jfnotk255

    Nice tests. But what does it tell you? Without using (measuring in) the normal PCV or blocking it you have now two PCVs in parallel. As you can see with the old and ne filter this affects your reading. But the blow by at the pistons will stay the same. So a better PCV only reduces the pressure in the crankcase, but not the blow by.
    I would just use a pressure gauge or it I really want to know the blow by a flow meter looped in at the PCV outlet of the engine head.

    • @PawelPienkowski
      @PawelPienkowski หลายเดือนก่อน

      This is something I also considered. With this setup, the reading strongly depends on the efficiency of the PCV. However, a good or bad PCV should not affect power losses or oil consumption-or does it?

      We have one at work with the Allison transmission, and I can't recall it ever needing anything at all with those miles. The only thing is 5k mile oil changes, and a battery replacement all its life.

    • @JosephSamsor
      @JosephSamsor 2 หลายเดือนก่อน

      Well for one, “duramax” could mean a complete pile of shit, or pretty decent. Know your different models and the issues with each year, not just the fact that it’s a duramax. It’s the same for powerstrokes or even Cummins.

    • @sc3ku
      @sc3ku 2 หลายเดือนก่อน +1

      It could blow the oil cap clean through the hood and sellers would tell you it had no blowby, then get mad at you if you call them out. Needle in a haystack to find anyone with scruples.

  • @milstar71
    @milstar71 หลายเดือนก่อน

    The test it self is a great test, however on newer engines crankcase is been recycled back into the intake before the turbo. If your air filter is clogged turbo would create enough vacuum where it will effect the reading and if the air filter is really dirty it might even suck oil out of your oil separator. If the drain tube from the separator drain at the bottom of the oil pan or in kubota's case they have a tube goes down to the bottom of the pan on the inside and turbo will pick up oil from the oil pan if the filter is dirty enough.

    why wasnt the crank case vent plugged in order to get an accurate reading? Isnt that what cummins procedure is?

    • @JoseTrejo1
      @JoseTrejo1 2 หลายเดือนก่อน +2

      That was my thought exactly. The test should have been from the oem crankcase vent location only and not from the cap while recirculating the crankcase back into the engine.
      If all that you have Dave is an oil cap test port, then pinch off the crankcase vent hose that recirculates back into the engine. Also, I’d recommend adding a 2ft hose after the meter and depending on some of the ccv designs(filtered/unfiltered) use a new one as some of the high mileage units could be pretty plugged off giving an inaccurate reading.

    Hang on . Did I miss something here . . . Measuring from the cap will cause invalid results unless you block the breather pipe as your bringing a 2nd breather and factors such as breather filter restriction and air filter restriction into play .
    So either measure at the breather into the intake or at the cap and block the other .

  • @KennethMyers-i2t

    It’s amazing you got that many trucks with that much blow by and most of all the manufactures don’t care whatsoever to improve the system and make it better where there’s no blow by no drag cars they do it and they take care of it on blow by an over 5000 hp but these trucks heremanufactures incompetency of the motor properly last 300,000 or 500,000 miles
