Top 7 Things that could be SECRETLY Hurting your Diesel Engine.

[@realvanman1]

Agree on all of it, and will add that engines make heat as a byproduct of doing work. So, once your cold engine has had oil pressure for long enough to be circulated throughout, put it (gently!) to work! And continue working it gently until it's closer to normal operating temperature.

[@terryfrederickson2774]

um,,the heat is from burning fuel ,,it is after all a heat engine and work is the by product of heat ,

I'm NOT a mechanic but I did buy my first Cat in 1984. When I change my fuel filters I change my primary run the truck, then change the secondary to avoid getting too much air in the system. If they're both changed at the same time that's when I've had issues getteing her started. Happy New Year.

[@TheBlueangels9]

Brother if your check valve right by your primary filter housing is bad that what happens but if it’s working right you shouldn’t have problems changing them both at the same time

[@johngoldsmith6629]

Yes Sir, prefilling filters, makes me a lot of money. I have had a couple piston failures, oil filter was prefilled. The foil was apparently pushed into the oil jug. Poured directly into the unfiltered port. Eventually made it to a spray jet and plugged it up, early 92U engine. Second, MBN, oil filter must have been dropped in oil dry. As I dug parts of oil dry out of two spray jets, again seized pistons. Improper maintenance, is the fast way to the repair shop. Also putting new dirty parts on. Had a REGEN engine that I replaced the fuel enable valve. Before I installed it, I took starting fluid and washed it off, onto a lint free rag. You could see the metal fragments that washed off the threads. As my first cousin told me once, John you can never be to clean building an engine. Have a safe and a Happy New Year to the Josh Family.

[@AdeptApe]

Thank you John and have a great year. Hope you are feeling better.

[@misters2837]

Well Prefilling in itself is not the problem...being an idiot is going to ruin anything...But prefilling is better than starting an engine with ZERO oil pressure for 10-30 seconds. I have rebuilt thousands of engines...and prefilled tens of thousands of filters....I have NEVER had a Pre-Fill-Failure... But then again, I'm not an idiot... If one is not going to pre-fill oil filters...spinning the engine over with the starter to prime the oil system before starting it, is a better way... On the OLD Mack we had My Father would prefill, AND spin engine over with the "Engine Stop Cable" pushed in...To build pressure...Therefore the engine never fired without oil pressure...He also warmed it at 1000-1100 RPM for 15-45 minutes daily...That engine/truck went more miles than ALL of its "sister" trucks...

Who's "they"? If you're using Cummins recommended fleet gaurd fuel filters, they come with a plug in the center for a reason. Pre fill through the outer holes.

[@bertgrau3934]

On a Detroit, 60 series, I would install the fuel filters dry, then put around 12 pounds of air pressure in the fuel tank and mine had a bleed screw open it just a bit and wait for the fuel to come out. Tighten the screw. Start engine, it would usually start right off and run at about 1000 RPM and it would be just fine. Detroit even recommends to NOT use the electric fuel pump to prime the fuel system.

[@youtubeisawesome2487]

before the plug it was recommended by cummins to install dry and use primer pump to fill, and its much easier than spilling fuel everywhere especially if your using the extended life engine filter, just bleed it at the compucheck port, easy peasy. @@ericb8030

[@ianloy1854]

@@ericb8030 Yes they do - but NOT because the engine manufacturer wants the filters pre-filled. Rather because if they are going to be pre-filled then it is better to fill them on the dirty side.

This why I keep my GMC 2500hd in my garage and plug it in before I go anywhere in the winter months. A lot of school bus engines get nuked because some drivers cannot be bothered to lift the hood each morning to check fluids or even check the ground under the engine.

[@jcurtis4082]

Nice, I find nothing to disagree with here. All good. 60 years in the industry and I have stopped asking the operators of idling engines if there is something wrong with their starting/charging systems. My sarcasm proved ineffective. /: I get that sometimes you have to leave them running. We did it all of the time in the Arctic. But the practice did make for more mechanic work and I was able to feed my family sufficiently for many years. And made me a lifelong proponent of oil/coolant/battery heaters or heated spaces. Ultimately idling costs add up to more than just the cost of the fuel. Since the introduction of electronically controlled engines one of my first stops when reviewing engine data is idle time and/or idle percentage (some differences in terminology between manufacturers). It's a well proven killer. Happy new years, keep up the great work.

The temperature dropped to well below zero, and when I got back to HQ, I started the car, then ended my shift, changed into my civilian clothes, and went to the car. It had started well, and idled well for around thirty minutes. When I attempted to drive home, the engine would not go above idle. I drove the eight miles home in first gear on the five speed transmission. I started using anti gel additives at that time. It was an ugly situation

[@anastasiszaroliagis5066]

Sometimes in Europe we add sae 10 oil with diesel to the filters to clean the system, is this correct ?

[@arcticfox5118]

As a rule with my paccar i only idle 15-20ish mins in the morning during winter. Usually just long enough to defrost the windows and get the oil to at least 120ish. Any less and my oil pressure will spike to 90+ which always concerns me. After oil gets to 120 it will spike to 70 when i start moving then drop back down to 50 as it warms which has been the normal running psi for it since ive owned it. Always been like that and the mechanics more or less shrug. At this point ive put 860k on it so why start changeing things when they clearly work. Also make sure that my max idle time unless as you said its like 140 degrees out is around 20 mins before i kill it. Usually it will be idleing through traffic lol. Otherwise i own an APU which sidesteps the its too hot issue.

[@crandonborth]

That’s because PACCAR uses high volume low pressure oil pumps instead of the normal high pressure low volume of say a Cummins. The oil being thick doesn’t flow real well hence the super high pressure. The downside is you have to run the same oil summer and winter as you’ll lose your oil pressure in the summer to the critical point.

[@fastinradfordable]

I knew an idiot that ran the wrong oil and tried to argue having 125psi was ‘better’

[@philiplieb575]

Paccar oil pressure is very high when cold. This is normal until they warm up

[@Mtbslacker]

There was a Cat training video back in the day that showed how oil fills gaps between moving parts at low idle vs elevated. It was showing how increasing the RPM pulls oil into these spaces creating a thicker cushion so to speak. Does your training dept still show those old videos on liner cavitation and whatnot?

[@jameskratzer2014]

For cold starts during below freezing temperatures, once I have the engine running, and oil pressure is achieved, I then bump the idle to no more than 800 rpm, then I monitor the oil temperature. Once the oil temperature is past 120, I’ll start driving it, but using minimal power and gradually increase the power as the temperature rises to operating temp.

[@redmesa2975]

Nooo… don’t raise the rpm at 10 degrees. Don’t want to starve the bearings, due to cavitation. Wait until the coolant temp begins to raise ,then idle up. Once it reaches 130 degrees, then drive away nice n easy. Keep the rpm’s under 1500, until coolant temp gets close to 180 degrees. I’ve seen Cummins techs come out, start a cold engine ( 30 degrees) and just pin the throttle to the floor. It’s not their engine, so they don’t give a shit.

[@ianloy1854]

Lubrication depends on the oil and the temp of the oil. Once the oil pressure is up if the oil and metal temp (for an engine that has no extra heat left in it) is above the lower oil rated temp you have good protection. The engine MATERIALS still need to warm up, so yeah no revving wildly, take it easy but KNOW you have proper lubrication. What temps? 0W -40C/F 5W -30C/-20F 10W -18C/0F 15W -9C/15F

On my 2018 Pete 567 with the Cummins X15, when I change my fuel filters, I install both new ones empty.

I then start the truck and it runs normally. Easy.

[@mbergheaud]

Does this also apply to common rail/direct injected diesel engines?

[@TheBlueangels9]

Hi Josh on the subject of warming up on cold start I have to say even though mostly same rules apply to most diesel engines how ever there are some differences in technicalities even between same manufacture engine models for instance c7 and c15 are different in cold start up settings for example c7 as soon as starts rpm jumps up for while and that’s because displacement is not quite enough to make a proper heat on compression stroke when cylinder walls and pistons are cold , on the opposite side c15 ideals on 500 rpm right after cold start and it depends on how cold ambient temperature is it might take up to couple of minutes to jump up to normal ideal speed which normally is 6.75 to 700 rpm and per caterpillars themselves you don’t have to warm your engine up as long as you have proper oil pressure and they recommend that you should drive in low RPMs if you have to move right away however, with all due respect to everybody’s opinion, I owned, drove and worked on my own since 1984 and I can tell you there are many reasons that I personally warm up my big cats at least to 130° before I roll and one of them reasons are oil pressure is too high most of my trucks are at 80 psi Even at 40° ambient at a start up and I don’t like to cause oil leaks the second most important reason is cylinder liners and Pistons are obviously made out of different materials and for sure they don’t warm up at the same rate neither do they expand at the same rate so you see what I’m getting at. and that’s why cat setting it self starts up at low rpm then jumps up And lastly, about Westgate of Turbo, I have to disagree with some of your input. I think they are totally horseshit, and everybody who has single turbo cat should either change it to non waste gated turbo or pinch that stupid hose, for it causes more disadvantage, than advantage if any,like it derates Turbo boost, raises, EGT greatly,causes bad fuel mileage, and I can keep on going, after all it sets to open after 25 psi (really 🤨😒)and I think the only advantage it would have to lower the back pressure of the exhaust manifold, which that has never been a problem with GarrettTurbo or OE cat equipped turbo which is 1.42 AR at its hot side which That means,is big enough even without wast gate To flow all the exhaust gas through out the turbine housing without creating back pressure so in reality, there are no advantages to have that damn waste gate it’s almost like having a very bad leak from air to air 😅however you should definitely have a pyrometer gauge to monitor your EGT and not to let your boost go up excessively which is over 38 pounds except accert twin turbo

The topic of idling, is optimized idle good or bad? I had a 2020 Cascadia that would start 20 times a night, I know that system has been around for ages (at least 20 years) but it would always fire, idle real low then bump up 6-700 and just about every day it would regen while parked (I was on paper so obviously I didn’t sit still long). But occasionally it would shut off during regen and fire back up and start regeneration again. It regenned on the hwy as well like it should, then would repeat the process. I was in and out of Freightliner it seemed every week because my cruise would set itself at governed speed, which was 78, it would set itself on ramps, in traffic, all kinds of wonderful places. I still have video of it doing it on the off ramp in Yakima, you couldn’t cancel it and there was no warning, it would just do it. Now that has nothing to do with idling, but there were sooooo many electrical issues with that truck so I can only assume other issues were happening. The truck only had 71 miles on it when I got it so everything was warranty work, but I was in every Freightliner in CO, CA, WA, OR, ID and UT it felt like. I ended up getting out of the truck, but they blamed it on new trailers, wheel speed sensors, driver not knowing how to set the cruise was my favorite one. I get the dash looks like a video game now, but it wasn’t like I was driving a space shuttle. Long story short, could any of that been attributed to opti idle? As in the electronics of it? Denver Freightliner ended up fixing it, but by that point I was out of the truck, but that was after over 170k and I couldn’t care less what happened to it

When you're idling your diesel engine you are not wasting a lot of fuel. You're only wasting a littke fuel. With no load on the engine, you are burning the bare minimum fuel to acheive the crankshaft to rotate at 500-600 rpm depending on your engine.

Happy New year , as well to everyone else!! When I designed my fuel filter/system for my truck, I put pre and post filters valves. So that I can isolate the filters. Change the filters W/S ,, fuel filter. So close the valves pre and post, change the filters, as the fuel was clean so dumped it back into the fuel tank. lubed the filter O-rings and installed them. Opened the Pre valve/as well the fuel return valve to the fuel tank, then bumped the electrical pump in tank .Circulated the fuel back to the tank then let it sit for about 5 mins to let any air trapped in to rise to the return tank valve. Then run the pump again for a few mins to remove any air. Closed the return tank valve opened the valve to the engine. It fired right up. Yes I have left a few other things out but that is the just of my design. I wasted?? about a tea spoon of diesel. SO I FIGURED IT WAS A success!!! The Cat 0749 filter is rusting badly. so it is not going to last that distance of that filter change. Guess I will stick with the Donaldson 1000 and the 1313 or is it the other way around???

[@cbmech2563]

On my 97 7.3 powerstroke I did efuel with 2 spin on filters back on the frame rail, the rear tank is sumped and the fuel level is above the filter heads when at least half full. Pull both filters, put the primary on, turn the fuel back on and wait for the fuel to come out of the secondary head, put it on and then turn the fuel pump on and let it fill(regulated return system). As another note I've seen Cat heavy equipment with a "primer" switch on the frame near the fuel filters. That should be standard on all engines.

If your truck have DPF just delete it, it will save a lot of down time and save bunch of $$$ in your pocket

[@charlesb4267]

That all depends on what county one is in and if a reliable delete system has been developed, do it the wrong way and engines have been know to fail with huge $$$ consequences. Having said that, I know locally where I am there are some shops that do a lot of tried and true delete programs because of very poor pollution systems that can't handle northern winters with a must to be able to keep the engine running. Unfortunately it most likely also deletes any engine warranty !. And in the states if caught they treat you worse then a mass murderer by the sounds of it.

Simple solution, don't buy a Diesel.... lol.

[@robertchristensen7950]

Was wondering if you heated the intake air, would it be more reasonable to idle the engine?

Don't we call it cylinder glazing anymore?

[@shawnking4671]

I usually warm up to about 90 degs and then driving slowly till it warms up fully.

Been watching the channel for a little while now brotha, got a question for ya. How would you as a young diesel tech try and get your foot in the door. Going through the diesel program at Nic right now and been trying to find some sort of mechanic job over here in north Idaho. But just can’t seem to get anywhere, I’ve got 2 years of experience at a body shop and a lot of time turning wrenches. Any tips help! Have a good new year
