Engineer Deep Dive: 3.0L Hurricane Engine - Turbo Life, Oil and Intervals and More

[@Pickuptrucktalk]

There's been some questions about direct injection and carbon build-up on engines with this technology. I have asked about this with various engineers over the years and they have responded that the higher PSI of the spray nozzles, it atomizes the fuel better and removes this concerns. Here's an example of this explanation at the 3.28 mark of this video with a Chevy engineer. He is talking about the 6.6L gas engine, but this same information applies to most other gas engines. If you check out the spec charts online, you'll find the gas pressure spray PSI level for most is well above 2,000 with some being higher. The Hurricane engine has a "single high pressure pump providing up to 5,075 psi (350 bar) to a single fuel rail." kzbin.info/www/bejne/d5C5knl5pbZspLs

[@terrencejones9817]

Fuel pressure being higher makes zero difference. Most of the carbon build up happens on the back of the intake valves. A port fuel injector would spray fuel onto the back of the valve, cleaning it. A Direct injection engine can't do this ,because the injector is inside the combustion chamber. Now they can play with the variable valve timing a bit to mitigate some of this. But we had the heads off a 2022 6.2L gm last month. The carbon build up is clear. The only way to deal with it is frequent induction services, which currently GM does not require as part of regular maintenance. However, one of the first recommendations to diagnose a P0300 code ( random missfire) is to do an induction service with Top engine cleaner. The problem of carbon build up very much exists. GM seems to be fhe best at avoiding excessive build up. But it still happens.

[@Pickuptrucktalk]

@@terrencejones9817 The way it was explained to me is carbon buildup is left over fuel that wasn’t fully cooked. Higher spray causes better atomization and therefore you don’t have left over fuel. Thus, the carbon buildup on the back of the intake valves doesn’t exist. FYI - Ram has 5,075 PSI spray pressure.

[@terrencejones9817]

@Pickuptrucktalk Problem is that doesn't address what actually causes the carbon build-up on the back of the valves. It's not fuel, it's oil/fuel vapour from the PCV system. All engines burn crank case vapour through the PCV system. Higher fuel pressure will actually make this problem worse. That high fuel pressure dilutes the engine oil with fuel. That fuel in the oil causes higher pressure in the crank case. That fuel oil mixture is then sent through the PCV and its dumped right on the back of the valves. People that like to go on extended oil change intervals make this situation worse. The more fuel contaminated in your oil, the less it lubricates, the more the oil turns to vapour. Google the GM Dexos gen 3 spec. It's specifically designed to reduce oil coking/deposits in a turbo charger. The only way you get oil deposits inside a turbo, is if the shaft seal is leaking, or the oil is being pushed through the PCV system . My wife owns a 2018 equinox 1.5L turbo DI engine. I maintain it well. Recently in cold weather it developed a missfire. GM has a TSB about intercooler icing. When we pulled the intercooler boot off, it was full of water and oil sludge. The only way oil is getting into the intercooler is through the PCV system. I change the oil on this car every 3000 miles (5000km) I do an induction service every 25k miles to avoid the carbon build up. That being said, the discovery of oil in my intercooler, means I'll be doing another induction service soon. BTW, if you took a look inside the intercooler of any Ford Ecoboost, you'll discover the same issue.

[@Pickuptrucktalk]

@@terrencejones9817 all I know is the spray pressure is the answer I get from many different engineers at different companies. I’ll also add in the last few years I get confused looks from engineers when I ask them about carbon buildup. I take that look to mean they consider it resolved and have moved on.

[@tylerproctor4878]

​@terrencejones9817 I agree with you sort of. Better burnt fuel is gonna push back any meaningful carbon build up. How far it pushes it back? Who knows? 150k miles maybe. But yeah you are right. It's gonna happen and it makes it hard to look at these DI engines and not say it will eventually reduce the performance and longevity at some point.

[@erickisel8668]

Nobody will ever be able to convince me that start/stop technology is a good thing or actually saves a material amount of fuel or emissions.

[@alexgrindnshine2522]

As a mechanic I thought this was stupid idea. But in practice it works great and is sensible way to save fuel and put less wear on the engine. You can always disassemble it too.

[@markf8256]

Agree. From a practical standpoint most people couldn’t care less about the negligible emissions reduction. If it actually saved a noticeable amount of fuel (greater MPG) it wouldn’t receive such hate. As consumers we do pay a premium for this as the starters and 12v batteries are more complicated and much more expensive to replace. All of these changes to satisfy government regulations cost the consumer more. More up front and more if you like to hold on to your car or truck.

[@sixmarch]

Same! '19 Rebel with everything you mentioned.

[@facepalmdaily4404]

I've repaired many 5th gen hemis. My advice, if you plan to keep it for any length of time, is to go ahead and have the camshaft changed to a quality aftermarket cam now rather than later. People blame the lifters, but it's really the poor manufacturing of the cam. It's brittle and will start spalling under normal use. If that flaked off metal gets into the camshaft bearings and fries them, know that those bearings are non serviceable and the whole engine would have to be replaced. Better to swap for a quality cam before risking that. I'd also change out the upper control arms. Stock arms are composite material..... PLASTIC. Not a week goes by that I don't see a 5th gen come in where the ball joint ripped completely out of the UCA after the driver hit a pot hole. And be extra cautious changing your oil. They mount the oil filter directly above the tie rod bushings. Engine oil deteriorates rubber bushings. That's why they put the oil filter there.... to wear out parts faster. Lastly, go ahead and fill the gap along the top of your rear window with flowable silicone (permatex). The window has a thin plastic ring. Instead of the adhesive going directly on the glass, it goes on that ring, so when the plastic cracks, and it will, there's nothing to keep the water out. These trucks are designed to fail. But if you put some cash in early to upgrade parts, you'll be a lot happier later.

[@IamChucky_]

@@facepalmdaily4404 thanks for the advice. Yes a aftermarket cam and headers are definitely on my to do list!

[@facepalmdaily4404]

@@IamChucky_ Good deal. It's an expensive up front cost, especially if you are paying someone to do it, but it sure beats the alternative. I've seen guys need new engines at 50k because their cams spalled and wrecked the bearings, or the metal gets down and wrecks the rod bearings. And I don't care what anyone online says. If your tick is coming from spalling on the cam, no thicker oil is going to fix it. Those guys fixing their tick with thicker oil had lifters that weren't properly pressurizing with oil. the slightly thicker oil will help with that..... not a cam problem and cam problems are the bigger occurance.

[@facepalmdaily4404]

@@go_dawgs_8290 Mild rephrase: Design their VEHICLES to fail. My bad. Engine is part of it, though. They have been in the habit lately of designing them to inhibit owners ability to work on them themselves and engineering them to cause more problems. Few examples of built to fail..I'm speaking specifically of the 5th gen and 5.7 hemi. Starting small: There used to be a bleeder bolt on the top of the water pump. When you did work on the engine and needed to refill coolant, it was as easy as removing that bolt and filling till coolant came out of it. System is purged of air(usually). Good to go. They took that away and now require vacuum filling the system. You used to be able to access the lifters without pulling the cylinder head. Not anymore. Intentional decision in my eyes considering they were having tons of lifter issues before that and instead of fixing the issue, they moved the lifters to make it a MUCH more expensive repair. The rear window leaks because Ram puts a thin plastic ring around the entire window. The adhesive bonds to that, rather than directly to the glass. So when the plastic cracks, because that's what plastic does, there is nothing to keep water out. Ram knows this. So what did they mount directly under the leaky window? The Etorque battery and the RF module for the key fob. The window is designed to leak and updates to that design have never strayed from that plastic ring. The oil filter. Front suspension parts, particularly the rubber boots and bushings, don't like engine oil. It deteriorates them. So Ram placed the oil filter directly above the tie rod boots. If you take it to a shop to do the oil changes, as most people do, the shop drops the filter, lets the oil spill and then just wipes it up after. Every oil change oil gets on the boots. I can't count how many times Rams have come in with front suspension issues and, surprise surprise, it's mostly the passenger side. FCA will tell you to change your oil every 5k miles. I've contacted them myself and that's what they point blank told me. Particularly on the 5.7 hemi. Change it every 5k with full synthetic. However, the oil life percentage gauge they put in the dash doesn't tell you it's time for an oil change until you are closer to 10k miles. That's intentional. Now the camshaft. The cams they put in are brittle and prone to shedding metal. Everyone points to the lifters, but it's the cam. It's not properly heat treated, so the metal begins spalling. That spalling eventually wrecks the lifter roller. People take the engine apart, find the wrecked lifter and think that's what did it. It's the other way around. Brittle, poor camshafts. They never updated it. I've seen plenty of cams covered in spalling without the lobes being flattened (yet). Every bit of spalling is more bits of metal floating through your engine. Plastic upper control arms. I've lost count of how many people have brought their trucks in because the ball joint completely separated from the UCA after they hit a pothole. So yea, I misspoke in my previous. I meant to say Vehicle, not engine exclusively. So many things about the engine, trans, body, suspension.... all designed to cause more problems. FCA stacks the deck in their favor for failures. I could keep going, but I've written a short story here already.

Good stuff, Tim! To have the chief engineer explain some of the questions that everyone has about this new engine was so cool. I'm glad that you asked about the durability in relation to turbos. I'm not a Ford guy, but one thing they proved is that turbos engines in trucks do have durabulity and longevity, as witnessed by their Ecoboost V6s. That will likely be even more true for Hurricane due to its straight-6 design requiring fewer parts. It is concerning that yet, another automaker has 10K mile oil change intervals. So many automakers have gone to this standard and it is so aggravating. On a boosted engine, the oil is doing so many things to lubricate the engine. That causes oil breakdown due to many heat cycles. I don't care what any engineer says, ask any race engine builder and they'll tell you the truth. On top of that, investing $100 in an oil change w/ quality filter at 5K miles max is one of the best ways to ensure longevity. And WHYYY NO ENGINE OIL DIPSTICK?!?! Ugh... That Chrysler Turbine on Alan's back drop is still one of the coolest concepts that was never built.

My first turbo car was an 86 Dodge Lancer ES turbo and it was one of the most reliable vehicles I have ever owned. I have been driving turbos ever since.

[@htschmerdtz4465]

Two sides of the coin: I had a 2.2L with a liquid cooled turbo in a 1984 Dodge Daytona and it worked well, no real reliability issues, all the way through 100k miles. There were some sensor issues and I did have to replace a cat, but overall, the powertrain in this car--which was a beater, a salvage car--ran pretty well, never burned oil, never broke anything internally until I sold it somewhere north of 160k miles. I did also replace the turbo, which didn't fail, it just got a little noisy, but the job was easy, so I did it to be safe. On the flip side, the air-cooled turbocharged Continental TSIO 360 in my airplane, not so great. These engines have turbos to maintain power, not boost it, so the engine will still put out plenty of horsepower as we climb higher or fly on hot days. They've changed little since the early 1960s and are not intercooled, still don't have EFI, ECMs or electronic ignition. We added an engine analyzer so I always know what is going on internally, but still, we have to baby this $60,000 engine so it doesn't grenade early and expensively. The engine has to have low-lead avgas, and like a dirty gray tsunami, the eco-woke are going city by city to ban the sale of this fuel.

[@Ratkill9000]

Test drove a new 2025 Ram 1500 with the SO Hurricane. I was underwhelmed. Put it this way, you leave traction control on and you give it a decent amount of throttle, that thing will go hard into traction control and make you feel like the engine is in limp mode. Thermostats on these are having issues at current where they are falling apart internally and causing high coolant to overheating conditions. Now since these engines are still new and don't have many years on them, its hard to say if the oil level gauge in the IPC will ever fail. There's always a greater than 0% chance of that happening, but put it this way, BMW and Mercedes has been doing similar stuff for nearly 2 decades now. Granted I don't follow either company closely, but ive never heard of those having an issue and same goes for Mini Cooper since they use I think BMW engines. That is not yo say it won't be a problem. Those companies have used ZF automatic transmssions for years without any issues, and Chrysler has been using them for a while and they have the same constant issues across multiple lines. So clearly the other manufacturers know what to do better.

[@charlespapineau5428]

I can appreciate Alan's comments on turbo engines from the 80s and 90s. Today's engines are designed with turbocharging in mind to try to mitigate the past reliability issues. However, turbos always bring more complication over a naturally aspirated engine. They are more mainstream because of the power expectations of customers and the CAFE targets of the government, plain and simple. Real world function over extended time will be the only real test for success. I'll be very interested in how a work Ram truck or a Grand Wagoneer that does a lot of towing will fare in ten years with this engine. I bet the electronics wig out before Alan's engine does.

For all the people that want to keep their trucks as long as they will last and believe that no added harm comes from running your oil to 10K miles....Good Luck. I also question not having duel fuel delivery.

I currently own a 2019 3.5 ecoboost with DI and Port injection with 81K miles. I have all the fluids changed when they're supposed to be and the oil every 5K along with tire rotation. So far it's been flawless....keeping my fingers crossed. 🤞

I do change oil often. I'm old school and it's not that expensive. I think Subaru has this turbo science down pretty well. They had some problems in the early years and overcame them. My wife was very observant as well. That car could pull 20 PSI of boost, but it could also climb any mountain in Colorado at 5 PSI or less. At 10,000 feet , 6 PSI is just atmosphere in the cylinder. It's hard to change people's perception though! 😎

@@paulhunter9613 , you know it seems that way. That would more likely describe a roots blower. They used to have that roll at idle, because they would build up a little boost at idle.

Most of these new engines though seem to need boost to be sufficiently powered, LOL.

​@@kensnyder2340 while I don’t have a boost gauge to view, an eco can be driven normally without getting into the turbos I think.

Alright Tim. So at the 11:45ish you start talking about turbos and Alan does a great job of explaining how turbos can be reliable.

I watched these tests before and i have yet to find a single published result. Can you find them? Lastly, i think it's important to point out durability, reliability, and longevity are related but they are different. Just because you can run an engine hard for 150k doesn't necessarily mean it will last 300k under normal driving.

[@anglerfishcreativelighting6494]

Thank you for this interesting interview really enjoyed listening to it. I own a GW S3 with the HO 3L i6 engine. And prior to owning the GW I drove the GW S3 with the 6.4L V8 hemi that comes with cylinder deactivation. Drove it for a week. The one thing I need to point out is that during normal driving conditions, the hemi with the cylinder deactivation will get far better fuel economy than the 3L i6. It’s a drastic difference. Doesn’t fuel economy translate to emission? You’re burning less fuel for the same number of km traveled. The other thing is that the i6 feels sluggish. It takes a bit of time for the turbo to kick in. The hemi is more fun as it can accelerates very quickly. In any case with the GW your not drag racing so it doesn’t matter but to say that the i6 is more fuel efficient is a misleading. Like under what condition? Sure when your using all 8 cylinders of the hemi yes the 6 cylinder twin turbo is more efficient. New engine means it’s going to take a while to sort out all the bugs. I understand design and manufacturing very well it’s understandable that when you introduce a new engine no matter how much laboratory style fatigue testing you do in the end the real reliability test will be in the real world and unfortunately a number customer will be unlucky until they fixed all the issues with the new engine design. The engines that are tested in the lab are assembled under strict supervision. It’s not like they take an engine out of the assembly line in Mexico and start to test them. Mass produced engine will always be less reliable than the prototype.

[@rustyredram7197]

If the high output oil is 0W40 for film strength / thickness due to increased pressures / bearing loads, would it not be better to use the same 0W40 oil in the non high output instead of 0W20? Also I get the joke about checking the oil but I think you don't give enough credit, I would argue many more people check the dip stick than you think. My truck gets checked at least every two weeks as well as looking for drips on the driveway where I park. That is how I found a rust hole in my diff cover and replaced it before it became an issue. I have had a couple sensor failures on engine over the years, not many, but never a dip stick failure. Sorry, I will get off my soap box now. Very good video thanks Tim and Alan.

[@Pickuptrucktalk]

What he is saying is OW40 isn't needed for the S/O engine since it doesn't have the same performance. If you use it, fine, but you are wasting your money. For the dipstick, the oil life monitor is more useful for the "majority" of customers and it will do a better job monitoring the oil than checking your dipstick since it not only checks the amount of oil, but the quality of oil. You can still check it yourself, the computer will just do a better job.
