I’m betting Dave installed a one way check valve that prevents back flow after engine shutdown. If you Add up all those extra seconds saved on engine startups, that ends up being a significantly lower amount of time saved in dry start time and it looked like there was oil instantly flowing (albeit at a lower pressure ) when cranking engine. Nice upgrade Dave! Love your videos.

@jacobmartin1951 7 месяцев назад

I agree with you, that’s probably what he did. My question is when changing the oil will that mean the 2 quarts of old oil stay in the motor and not be able to be drained?

@ejohnson2720 7 месяцев назад

@@jacobmartin1951 Great question! Most probably that is so. Partial solution is to add 1-2 qts of fresh oil, run motor for 30 seconds and re-drain oil, and re-fill with normal amount. You will replace much of the dirty oil with fresh oil, and the new filter can pull the rest of the contaminants out during normal operation. Alternatively it is possible to install a fine particle bypass filter, but that is better suited ($$$) to heavy truck applications.

@jacobmartin1951 7 месяцев назад

If I had one of these new high output diesel engines that are in these new trucks I would most definitely add a bypass filter. I also like the idea of swapping to the bigger and better CAT filter.

Reading some of the replies that other subscribers have contributed here, gave me several ideas about various ways of Pre-oiling engines before start-up... I was wondering if anybody has installed an accumulator, with an electrically controlled valve to open it to the Lube System.... As the ignition switch is activated, that electrical circuit could send a signal to an electrically controlled valve, on a hydraulic accunulator , to pressurize the engine oil directly to a point in the engine lube system.... 11:57

Being 70 years old I remember in 1971 Chrysler came out and advised owners NOT to use LEE Oil Filters. Chrysler said that the LEE's allow engine Oil to drain back into the Oil Pan and thus every time you started your engine the Oil pump had to refill the Filter being akin to a Oil Change or First start after Oil service. Now here we are 2024 . Some things change and some do not. Great content. Bless you and yours.

And they where damaged from a lack of oil in the sump. 17-19 got really bad crank case breathers that clogged and cause the engine to consume oil and company trucks don't ever get the oil checked.

Go back and look at how American manufacturers built airplanes during WWII that, at the end of the assembly line, flew off into the war. That wasn't by accident. After the war US manufacturers got lazy and cost-cutting, and QC Guru Deming went over to Japan and taught them how to do it, leading to their quality TVs, cameras, optical equipment, machinery, cars, etc. There is always a battle in companies between the people who want to do it right, and the people who want to do it quick and cheap.

@@TEXMECHANIC Have you ever worked in manufacturing? Quality starts with the raw materials and works all the way down the line, so to speak. One of my employers machined aluminum parts for a major airplane manufacturer. They have a paper trail for each lot of aluminum that they receive. Each step in the process has a quality check so bad parts aren't sent further along. I started working for a major GM parts supplier in the 1980s and have worked in heavy-truck, off-road, and aerial lift vehicle manufacturing as well as parts suppliers to those same companies. There are some rare failures but a properly-designed manufacturing process integrated with QC at every step goes a long way to all but eliminating most failures.

Great content as usual Dave. I run a repair shop and think along the same lines- always trying to figure out why things fail prematurely and try to improve the end product and make the repair last longer than the factory did. I really like what you did with the oil system. There were a couple comments I saw in regard to the system being open on top (no turbo installed) and while it is true that having the turbo installed will help hold the oil up, gravity is always pulling down and all bearings have tolerances allowing air to enter the oil system starting on top and filling the void left by the oil going back to the oil pan. And as an engine ages those tolerances increase which allows air to enter behind the oil moving down even faster. Then add in the temperature factor and when you shut down an engine hot, that oil will move back to the oil pan that much faster due the lower oil viscosity. There are also a few questions and comments in regard to the oil stuck in the engine when doing an oil change with the check valve (I think the technical term is foot valve) installed. I think there is less oil left in the engine than one would think. I always remove the oil filter first and then drain the oil- most of the oil above the filter will drain out. In the grand scheme of things, that quart that would be left is inconsequential if good maintenance is performed/kept up with. Think of the 7.3L powerstroke- there is about a quart of oil up top (in the HPOP reservoir) that most people don’t drain when doing service and it is really inconsequential if you do proper maintenance. I would go as far as say it would be better to leave the oil there for quicker startup lubrication after service. I think where this will really make a difference is as the engine wears (I don’t think it will wear as fast as if there was no check valve due to quicker oiling on start up) and not just the engine but the turbo as well, this will really help keep the oil where it belongs. Not to mention, if you don’t drive every day, it will help with or eliminate dry starts from day one. Thanks for all the quality content, keep it up!

I’ve been a part of 6.0/6.4/6.7 diesel forums for a long time. Never really saw a rash of these failures unless there was an underlying cause such as lack of maintenance or user error. The 2011-2013 motors did have some turbo and valve issues. Either way this is great stuff. My 6.0 takes about 3-4 seconds to move the dummy gauge but after 250K tear down it looked good.

Check/foot valve good simple solution for sure.

I thought that might have been your idea just on smaller scale. Thanks for the videos, I learn from each one, which is so refreshing for me.

@recklesstim 7 месяцев назад

Just adding a check valve (foot valve in this case) does come with several drawbacks. There are losses in flow due to the restriction of the foot valve and it will work the pump harder while pumping less volume. It also prevents a complete oil change. I'm sure the "One simple trick that engineers hate" has been tried and abandoned by the auto industry for a very good reason.

@PJHLR 6 месяцев назад

All check valves are not created equal. If you select/modify the right check valve, the slight reduction in oil flow will be negligible. The oil flow on a normally well maintained engine will be in excess of the minimum required flow rate. Compare how high the oil stream going into the plastic cup before the fix versus post fix. Not a significant difference. The extended life due to reduced oil starvation on cold startup far exceeds the little reduction in oil flow due to losses in the check valve (restriction and turbulence). The video illustrates a very good engineering design tradeoff for drastically increased engine life.

Nice to see folks that have pride in their work and look for solutions. I think the big automakers don’t want to fix some things. I worked in emergency power field, some large engines we used, 50 and 60 liter engines, had prelube pumps on them that could be programmed to run every thirty minutes until the oil system was pressurized. This was to prevent this same problem when the generator was started in an emergency start situation for a hospital or other critical facility. They also had block heaters on them to keep the cooling system 90-120 degrees. These engines held 48-110 gallons of oil depending on the oil sump configuration and other items

Excellent work. A definite fix so long as oil change intervals are maintained due to the two quarts of dirty oil left in the galleys after an oil change. Here’s the factory fix. Computer controlled primer pump that works in conjunction with a wait to start light that disables cranking until a set oil pressure is achieved. Then cranking enabled with pump disabled when a pre determined rpm signal is detected by the engine ECM. I like your fix Dave since I could grow hair waiting for the manufacturer to act.

@kylekelley213 7 месяцев назад

Should be like the glow plugs before you can start here should be a button before. You can start the truck that circulates the oil with an external pump. So the check valve isn't keeping that oil up there during oil change.

@scottlawson9206 3 месяца назад

When I purchased my 250HD with that motor new from the dealer, the very FIRST THING I did was to install a prelubricator system. So that prior to startup, an electric oil pump would fully pressurize the entire oil system, preventing dry startups. The unit I purchased also had a post lubrication feature, so that upon shutdown, the pump would run (I think for two minutes) to help cool the turbo and its bearings to prevent coking the bearings as it sat there soaking (otherwise non-flowing oil) in the heat.

Reposting my comment on Dave's Part 1 video - I have a Ford 6.8L V10 gasser in a 1997 Class C motorhome. Whenever I put the vehicle into storage, I remove the fuel pump fuse so the next time i start the engine, it will crank without fuel. When starting the next time, I crank the engine for about 45 seconds hoping that's enough time to get the crankshaft, cylinders & cams lubricated before replacing the fuel pump fuse and starting the engine. And you bet, whenever I change the oil (every 3500 mi), I fill the NAPA gold (Wix) oil filter with oil. Engine has 80K miles on it, and burns zero oil. Thank you this video Dave - your video confirms my '78 BSME intuition that I haven't been wasting my time! And I sure hope Ford engineers are watching & following your channel!

Problem is people go by the computer on the truck and change the oil every 10-12k miles instead of 5-6k. The other reason for failures is people tuning them to crazy power levels and running them like drag cars. Cummins is a good motor but theyre not bullet proof, they have major problems with turbo sooting up and head bolts stretching. Take care of things and they last its amazing.

Back in the day when i worked on heavy equipment, some company had a unique system to precharge the oil system before cranking the engine. I only saw it on one unit that i worked on. The systen had an oil pump pigeyback on the starter. The starter drive ("bindix")could not engage the flywheel until after engine oil pressure was reached. It sounds like something of this sort would be good for this engine. The electric pump motor could be an independent seperate unit. After engine start you would have this axillary unit to stop running. If i had one of these engines, i think i would seriously conjour up something of this sort, especially after viewing this magnificent demonstration by such an experienced builder. Emergency generators in hospitals have to maintain oil temperature and pressure along with water temperature 24/7. So, they are using an external charge pump. Wow! What a fantastic heads-up demonstration on this engine. Thanks a million for sharing your knowledge and expertise.

Take a straw and place it in a glass full of water, then put your finger over then end and lift it out of the glass, the straw will keep the liquid inside. But when you remove your finger from the top of the straw, the water will drain. The same can be said about not having the turbo on top of the engine, you have removed it from the equation, like the finger on the straw, allowing air to enter the top of the engine and the oil will drain back into the pan unless you have put some sort of check valve to keep the flow stopped. Bad thing about check valves, sometimes they stick open or stick shut. Sticking shut will starve the bearings of any oil. Bad consequences.

Both this and the first video made a lot of sense and thank you for your efforts. I am NOT a mechanic and do not pretend to be. But I would guess it is a one way valve in the pickup tube. That way the system stays "Charged". I have to say though, my first thought is. Do the manufactures allow for all the piping and such when they mark the dip sticks as to low and full marks? It highlights something which never thought about. If say you check your dip stick and it is sitting around half way. Potentially when you start the motor. You could in fact be draining all the oil in the pan just to fill the piping and tubing and that is before actually starting to do what it is there for. Unless when they put those marks on the dip stick that is taken into account. I would assume it is. But, you know what they say about assumptions.
