Most Common Issues With The DD13 DD15 DD16/ Detroit 15/ Semi/18 Wheeler/Diesel truck/ DD15 Issues

[@Bentfrombeyond]

I worked in a non-diesel shop at one point, and the one thing I couldn't understand is why some mechanics would be so guarded and not want customers to know their own vehicles, having basic knowledge about your car or truck makes it easier to point a good mechanic or technician in the right direction and save you both time. I appreciate channels like yours for being informative on things like this!

[@Montoya1991]

Because those are scam artists, they'd rather you come back and spend more money but like with every profession, there's good and bad ppl in them, Adam here is definitely a good one for helping out ppl. What the bad ones don't understand is that they lose their customers by their shady tactics which makes the bad ones losing more money in the long run because the customer felt robbed and looked somewhere else to take their cars. Same thing with doctors, I never went back to a doctor that I felt he didn't put any effort into helping us get better while I kept going back and recommended doctors that seem genuine in helping their patients.

15 years driving big rig here. My advice for anyone who is looking for a truck to buy for first time. Series 60 and cat engines are the best. If you are not in california buy those without def. But if you are in california then there's not much choice. Never buy cat motor if that truck has def system because it gonna keep blowing turbo.

[@johac7637]

Cat engine with Def, they quit making truck engines before Def, it was egr that ended them. Max force were Cat blocks at beginning only, then blocks came from Europe. Tell me which Cat eng had Def in trucks.

[@Bakir07]

Cat with def? That just shows ur 15 years is bullshit.. bye

[@tangydiesel1886]

I'd go another step and say skip the dpf only trucks as well. Honestly, I'd take the def ones before the dpf only rigs, but skipping both is best if possible. And yeah, no true highway cat had def. But a guy should still skip the dpf cats. I'd even add the N14 Cummins as a good buy, but they're getting up there in age.

[@tangydiesel1886]

​@@johac7637the dpf in the cat was worse reliability wise (mostly to the ard head) than the egr. But yeah, it all wasn't good.

[@johac7637]

@@tangydiesel1886 so again, which Hiway trucks had DPF as none had EGR, in the Cat engine option, construction machinery is a different storyline, as as the EPA tiers rose so did emissions treatment, but Cat went out of On Hiway engines as they wouldn't go with EGR.

746500 miles on my 2015 and the only small leak I had was oil pan gasket. Other than that it never leaked. All other OO in our company are driving Pete's with ISX's. All around the same milage. Mine gets better mpg while there's a little more powerful. We've all done similar maintenance to it, but Cummins is waay more expensive to fix. Turbo, injectors, fuel pump, you name it. Almost double the price of Detroit parts and they don't work particularly longer or better than Detroit. I'll stick to my dd15.

[@jasonmarshall7374]

We had the low oil pressure problem on a DD13 in a Fire Truck. Unfortunately we didn't catch it in time and it cost us $50,000 for a complete engine replacement. There is a recall on this problem but our truck was not included in the recall even though it was the exact same issue! Engine had less than 40,000 miles on it! We also had a problem with the oil cooler causing oil and coolant to mix. These Detroit DD13'S (mostly a rebadged Mercedes engine) seem to be way too fragile for Emergency vehicles. We have had numerous other problems with them as well but I don't have all day to list them all! Also, because our engines were not part of the recall, we received NO notification of the low oil pressure issue and Detroit Diesel flatly refused to cover any part of it! Big thanks to TAT Express for putting this information out there!!

Just giving you a shout out. my freightliner is leaking from the 3rd spot in your video. What is an estimate for the repair or how worried should I be? Thank you

[@shrimpbrime6027]

It is, for sure, REQUIRED to check rod and main bearings on low oil pressure faults. The #1 cause of oil pressure are the tube orings between the pick up and the pump. Erratic oil pressure and low pressure are the symptoms. A manual gauge in the oil pressure sensor hole is recommended to confirm the fault with minimal engine run time as possible. If a single scratch is seen on any bearing, the 550$ cost of the parts is great piece of mind.

How many miles should be drive. Before transmission oil is change/check on. DD15

[@rrmobilemaintenancellc7272]

One of the biggest issues i encounter are with the Oil Pick Up Tube. Unfortunately Detroit thought it would be a smart idea to make it with plastic. Over time the heat/vibration can cause the pick up tubes to crack and you will lose all oil pressure. This can and almost always happens while you're driving and causes engine failure. DD13/15/16 will all fail if they run 7 - 10 seconds without oil pressure. SO if that pick up tube breaks, by the time that engine stops spinning you will need a whole rebuild or a whole new engine.

I ran a dd15 in a 2010 cascadia. Was great engine, pulled like a freight train. Only problem with it, lease truck from penske. Sensors go bad, we all know that. But they would replace the wrong ones and send it out the door. It was on a wrecker once a week for 6 months. Shut down while i was crossing the Chesapeake bay bridge! Not the trucks fault, poor service from penske. Had a few loaners in that time, another cascadia same engine, needed sensors replaced. Tech looked thru onvoard history, cel reset 144 times because they didnt want to fix it. Another one was a century with a 60 series. Another great engine. 65 around baltimore beltway and the freakin pitman arm fell off the box. After i told them there was toomuch play in steering. Had driven it 8 miles from the shop. Sorry bout the rant, the dd15 engine was one of my favorite smoother engines. Great vid

[@shawnbowman687]

We have two nice now junk cascadia DD trucks sitting outside the shop with the engines locked up from no pressure because the plastic oil manifold broke where the oil goes up into the block. Where it makes the turn to go up in the block it almost looks like a plastic plug that’s melted or molded in there from the factory on both trucks. That plug or cap blew out and it was basically pumping the oil right back into the pan Instead of up through the engine. We don’t reseal them we just throw them away and replace them just because we’ve seen that plastic piece break in two trucks in the last 5 months. Now any truck that comes in with around 500,000 it gets a Whole new pick up assembly. After seeing that we’re scared to reuse them unless it’s one of the older aluminum ones.
