Chalk one up for your rep. Hope ya have an extra 15K if you have a 6.4

 

If you had no oil pressure, you replace the low pressure oil pump, not the high pressure oil pump. That's a hour job with $60 worth of parts on the 7.3.

Yeah, I'd say that's a pro. How long would it take to replace the oil pump on a v-10, or if you lose an oil pump is it cheaper to just burn up the motor and replace it?

 

i was trying to figure that one out as well.......

 

Towed right at 15k yesterday and never came under 70 and went 385 miles on a tank of diesel fuel in a 29 gallon shortbed tank. Don't see a V10 doing that.

 

The signature rings true!

 

So does your avatar

Seriously though, I am incorrect on the HPOP, just funnin' you guys


We needed a little more zest in this thread

 

That's ok, we understand you v-10 guys are used to unscrewing and throwing away burnt out motors just like a lightbulb.

Apparently your motor is easier to remove than your spark plugs.

 

Assuming the Diesel cost you $5K more than the same truck with a V10 to begin with, I can buy 2174 gallons of gasoline with the money saved.I can still pull the same load,get to the same destination in the same amount of time,and get back home the same. If fuel mileage is your only argument-find a new thread-nobody's arguing that at all.

we all know what assumptions do...........

im just sayin'! atleast youre not still whining about the turbo.............

 

I never have whined about a turbo. Facts are facts,and an engine that utilizes a turbocharger will operate with a perceived "better" towing ability. The reason for this is the "perceived" ability of the turbocharged engine to pull without "loading up" or having to downshift,etc. Why? Because the turbocharger effectively increases that engine's displacement when under boost. Watch the boost gauge on your turbo-diesel next time you start up a hill. Attempt to climb that hill without any increased boost from the turbocharger and see how well the truck maintains speed.
I've driven non-turbocharged and turbocharged diesels in the past. Both 6.2L GM's and 7.3L IDI Ford's for a delivery/vending company. I drove them for 2 years. They were all the most sluggish,fuel drinking pigs that we had in the fleet. The truck I primarily drove was a '92 F-SuperDuty dually chassis cab with a 7.3L IDI non-turbo diesel. It had an E4OD and 4.56 gears. Dead empty, it would run OK. Not quick by any means-but tolerable. Load it up with anything over 2000lbs,and it was pathetic. Foot to the floor coming up to an overpass,and it would drop from 60mph to around 45mph. We had 4 of these trucks-all identical. ALL of them behaved this exact same way. A N/A diesel is a pig.We're talking about a 444ci, 21.5:1 compression ratio engine that can't make more than 185hp/360ft-lbs. Hell,even the "lethargic" '99 6.8L made 265hp and 410ft-lbs with only 415ci and a lowly 9:1 CR.
Jump forward to the Powerstroke....Direct injection, 444ci, 17.5:1 compression, turbocharged. 275hp/525ft-lbs. So you've added direct injection, lowered compression ratio by 4 full points and still gained 90hp and 165ft-lbs. How? By the extra airflow into the engine via that turbocharger. We had one Powerstroke truck before I left that company,and it didn't have the problem falling on it's face and losing speed on overpasses like the N/A diesels did.
Turbos are a great power adder. They make HUGE amounts of torque and hp with moderate boost levels.Add that to an already high CR and large displacement,and you have a perfect fit for a great towing engine.
Proof of the turbocharger's effectiveness is in the tiny 3.5L direct injected ecoboost V6. This little 3.5L makes 350ftlbs from 2000-5000rpms.That's approx 75% of the torque that my 6.8L makes and it's 51% of the displacement!
How is this possible?
A pair of small turbochargers-that's how.
You want a fair towing comparison between the Powerstroke and the Triton V10? Get equivalent year models equipped to the same weight/towing capacity as determined by the manufacturer,leave them stock as stone and go have at it. The diesels will typically have a slight advantage,but it takes them 2x the compression and a turbocharger to do the same job as the equivalent gasoline engine with a higher initial cost.

So the 6.4 doesn't need oil pressure to fire the injectors? I really do not know the answer to that question.

A bad oil pressure guage/sensor doesn't necessarily mean the engine has no oil pressure. It is just a sending unit/guage with no mechanical ability of the lubricating system.

Everyone thinks that rebuilding a V10 is cheap. If you have the mechanical ability to actually assemble the motor it would be cheaper than paying the machine shop for assembly but most people on this site do not have a machine shop or the ability to machine their motors for the rebuild and this is not cheap. When the motor seizes, you will bore the cylinders to the next size. You will buy new pistons, 10 of them. And you may need to buy a crankshaft and camshaft. Remember no oil means destruction to the internal moving parts of the motor. You will not be able to hone it and just replace 1 or 2 pistons. It doesn't work like that. If you were freshening up the motor than you could get away with a honing the cylinders if they were in tolerence.

Just my .02 with experience on engine rebuilding.

 

Right now diesel is costing me 2.89 per gallon and gas is costing between 3.09 and 3.29 per gallon. Now I know if you buy the cheap gas it is only .30 per gallon more when you burn more fuel to go the same distance and do the math, the extra price for the diesel truck is not a factor worth arguing.

Diesel 2.89 x 20 = 57.80 to go 360 miles
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Gas 3.09 x 30 = 92.70 to go 360 miles.
<o></o>
Savings of 34.90 to go 360 miles.
<o></o>
Savings of 349.00 to go 3600 miles
<o></o>
Savings of 3490.00 to go 36,000 miles.

Savings of 6980.00 to go 72,000 miles.

So at 70,000 miles you have broken even between the 2 and you still are saving money for at least the next 100,000 miles.

These numbers change drastically when you purchase better fuel.

Now I know that diesel used to cost more than gas by about a dollar per gallon, but I also know that it used to be cheaper than gas by more than a dollar per gallon. I am only stating facts based on fuel prices today here in California.

I thought we were looking at all aspects of the two types of motors.

 

Diesel is .10 gallon more than gasoline here right now,and has been rising for over a month now while gasoline has been steady or dropping.

We love our turbos. We know the trucks would be pigs without them. That is why, given the opportunity, we install better turbos on our trucks. To make more power. You guys can add turbos, we won't stop you. Who buys a truck to leave it "stock"? I think most people on the site like to modify their equipment either for looks or for performance. The gas and diesel are similar stock. Once we modify them, the diesel runs away from the gas.

So let's enjoy our trucks and wave to one another on the highways knowing that each of us has the "perfect" truck.

 

Exactly.
Some of us are working on a turbocharger setup for our V10's. That'll even the playing field a bit and close up that "running away from" issue.
