- ^^^ All I've done on my 2017 Powerstroke is change the oil and it is about as simple of task as one could imagine. However, I've only had the hood open 3 times since I bought the truck but I don't think I have seen the turbo let alone figure out how to change it.
- For all my 60 years of owning and driving many vehicles I have always done my oil/filter changes with very few exceptions. Then last summer DW 2004 Buick Rainier 5.3 V8 was totaled by a red light runner. We bought a Ford Edge ST with the 2.7L twin turbo V6. I have to take Ford word on the face that there are twin turbos under the hook as just about every square inch is something under the hood. I could not even find a route out of the bottom of the engine bay to run out the power cord for the battery maintainer when we stored it for the winter up North. I had the dealer do an oil/filter change before we left with points we got when we purchased it, and will most likely continue doing that. It is not that I am not capable, as I changed the oil in the two year old Can Am Spyder we purcahsed 7 weeks ago, which involve removing a lot of tupperware body panels. It is just the Ford Edge seems to have a big virtual circle with a diagonal red line on it on top of the engine similar to the Power Stroke and Duramax.

Well that kind of depends. If you are like 4x4ford where you will leave it stock and trade it in every 3-4 years without going past the warranty, then accessibility under the hood is not an issue. For people like us who will either modify, go well past the warrant period/mileage, and/or planning on doing our own repairs then it is a huge factor.
I know with my brother's old truck, I would not want to do many of the things I have done with my truck because of all the stuff I would have to remove and what is involved. I would have likely paid someone thousands of dollars to do what I have done on my own to mine. This would also take all the fun out of it because most of the enjoyment of moding is being there with my son showing him how to do it and seeing his face light up when we get to test the results of what we did. Since this truck hasn't needed many repairs, moding is my only way to teach him.- When asked for my opinion on the big three I just say go open the three hoods and then tell me.

Yes, there is considerably more available real estate under the hood of the Ram/Cummins compared to the Ford/Powerstroke. This was another one of my reasons for going with the Cummins; more room=easier repairs=less overall operating and repair costs over the long haul. There is a reason why most hotshotters use the Ram/Cummins! :C
Yeah, I have done my own work on my engine except for the water pump that was replaced under recall by the dealership. So for I have removed some engine exhaust parts, replaced the turbo for a larger fixed geometry turbo, replaced the exhaust manifold for a higher flow pulse manifold, and installed head studs. I also replaced the after engine exhaust system myself which was kind of a pain in the arse holding the downpipe on the turbo with one hand while trying to the clamp around it and the turbo flange with the other. Never had an issue with space or needing to remove a ton of plastic parts to get to stuff.4x4ord wrote:

I think the Powerstroke is pretty easy to get at once you get the cab lifted off.:)
Easy Peasy - do it on the side of the road all the time.blofgren wrote:

Your claim that v engines require more cooling capacity than inline engines is confusing me. I might believe that heat management in a V engine is more involved. I can see why a v engine might tend to run a little hotter (which could mean less demand on the cooling system). What exactly do you mean saying a V engine require more cooling. Are you simply meaning that the greater surface area of an inline engine can radiate a little more heat directly into the engine compartment vs a more compact v engine?
I think you might be on to something regarding the difference in the engine compartment. My father in law just came by to pick up a trailer and I looked at the engine bay of his F350 versus mine.
I took that plastic upper piece off of mine a few years ago. Without it, you can get a better look at both sides of the engine. The driver side has a ton of room between the block and wheel well. I can literally stick a soccer ball or maybe even a basketball between there. The passenger side has the turbo so there is less room, but still has a lot of daylight. My father in laws truck was the complete opposite. I was hard to see daylight from either the top or bottom. So maybe it does have to do with more air circulation under the hood being able to removing heat off the longer and thinner block. How much of a difference that makes? Not sure.
EDIT: I was easily able to fit a regulation sized football between the block and fender well long ways (11 inches).

It's actually not a claim. It is the truth according the PB/KW/PACCAR engineers and is one of the reasons why engines CAT 3408 or Detroit 8V92 is no longer around in the class 7-8 trucks anymore. The cooling system requirements were greater than the comparable inline 6 engines and added more weight which is a hot commodity on a commercial truck. The other main reason was that it was a fuel hog. As far as the exact or scientific reasons why V engines tend to run hotter, I have am not 100% sure.
I would still check that cap and the system for boost leaks.
The inline has many advantages over the V configurations especially with regard to servicing and especially in something like a class 8 truck where an inframe engine rebuild is common. I think the way the inline breaths can sometimes encourage better cylinder scavenging which can contribute to a more efficient engine. The reverse flow cylinder heads of the 6.7 Powerstroke is, in part, an attempt to gain better scavenging.
"it was a fuel hog" Might have been in part due to the challenges arising from the V block configuration. A fuel hog needing more cooling makes perfect sense. If one engine vs another burns more fuel to do the same amount of work, the less efficient engine is converting less of the fuel's energy to power output and therefore a higher percentage of energy is being lost. A small amount can be lost through the exhaust as unburnt fuel (smoke) or in the form of noise and vibration but the majority of loss is in the form of heat energy lost through the exhaust (higher EGTs), or into the cooling system. I am not certain but I think the idea of a V running hotter has to do with the heat from the engine accumulating in the V which can lead to all sorts of challenges from warming the intake air and fuel to heat stressing wiring harnesses and electronics. In my way of thinking about this an engine running hotter (assuming the same efficiency) is putting less heat into the cooling system.
I think the cap on my Pete was checked but I'll have it rechecked. I can check for boost leaks as well. Thanks.
