Powerstroke question....

[Diamondpilot]

Lets see, 260,000 miles, chip, and big hitch. Run, dont walk. This truck has been used and used hard. Trust me, I have 2 of them just like that. I run the crap out of them. Good thing is they are Fords and are as tough as they come. Difference is I have owned them since day one and put all the aftermarket stuff on myself. I know how its been maintained and used. Buying used like this, no way.

The Ford Severe Duty Intake (AIS) is the best intake kit you can get in terms of filtering performance, and it flows better than the standard filter as well. You can tell the difference by looking- a standard factory filter will cover the driver's side battery with part of the plastic housing, and be a flat, rectangular filter. The Severe Duty intake will have the driver's side battery exposed, and be an oval shaped filter.

I have the Ford AIS on my truck. I installed it and it was actually fairly cheap. Another reason that this system is superior to other aftermarket systems is that it is quiet in the cab. Not as much drone.

Always get the F350 SRW over the F250. Higher stickered ratings for almost double the legal cargo capacity.

260,000 miles in 11 years. That truck was well used and is nearing the end of its service life. Trucks with higher mileage are very much the exception.

Thanks for the replies. Appreciate talking me down off the ledge. But i had already decided to hold off. when i asked about the Diablo chip, the son explained that it made the tranny shift hard, but that was normal. At least he was honest.

I'll keep fishing around. Another one I found, was a 2000 that was advertised with 168,000 miles on it. they kept putting off faxing a copy of the title, had excuses. But i did get the VIN. Run it thru carfax and it showed issued title back in '07. Mileage on the title in '07? 171,499. Too funny.


I may buy an old beater till we head south for April vaca, and do some face to face shopping. Might head for Tennesse.

But if any of you guys happen top stumble across something, let me know. Basically looking for 2000ish PSD's or Duramax of that rough era. I only put on 15,000 miles a yr so an older one would last a while. Just looking for something thats not a northern rustbucket. 6 months of winter salt is rough on stuff up here.

my 04 f250 has some upgraded air cleaner.. uses a 9490 napa element.. a retangular deal longer than a shoe box, but otherwise about the same dimensions as a shoe box. All our f250 at work were converted over to that. we heard it was superior to the OEM setup.

my f450 with 7.3 also has ( not the same one ) an upgraded cleaner. My 350/7.3 is stock though..

patience will pay off.

when I knew my dodge 1/2ton was going, I started looking for a good replacement vehicle. I looked for about a year almost.. at first casually.. then a lil more involved the last 2 months. I needed more than a 1/2 ton as I was doing more stuff ont he farm at the limits of my .5t wanted the axle capability of a DRW.. liked ford.. eeded a dialy driver.. so didn't want a 4.88 rear like my f450.. needed 4x4 as there are dirt roads to my farm.. finally found a 99 f350 drw 4x4 for a good price. it needed minor attention.. some window motors and door lock solenoids.. has a non critical trans fluid drip.. other than that it's a good work truck starts good, and gets down the road. as a side benefit it had a nice flip over GN ball in it so I can pull my GN if needed. I bet you I looked at 15 of them and missed a few better ones by minutes on the phone.. but patience paid off.

Basically what i'm doing. Learning whats a good deal when i look at it. learning a less than truthful seller when i see it.

i sold my 1/2 ton dodge, it was nickel and diming me to death.

Thanks for the input everyone.

 

[Soundguy]

kinda like buying a tractor.

learn to read between the lines.

'needs clutch adjustment' means, clutch IS already slipping, likely worn out.

etc..

Another question. 2001 PSD with "cold air intake" and after market exhaust. Whats a cold air intake?

 

[56FordGuy]

Whats a cold air intake?

Bad. :laughing:

Usually an open element, oil/ gauze type filter. Good air flow, lots of noise, poor filtration.

 

[flyingcow]

I put 8,000+ miles a month on a diesel truck, can't imagine why they would put a substandard air filter. no quicker way to eat the motor.

Because the producers of these aftermarket air filter systems claim higher flows and more HP. Kids, and even some adults, put these oiled filters on everything in hopes of better power and since they are washable some folks think they will save money vs. replacing the paper filters.

Yes, you will destroy the very very expensive diesel engine very quickly with poor air filtration. Diesels go through much more air than gas engines since there is no throttle plate and with force feeding by the turbo. Every time the intake valve opens it gets a max fill.

The Ford air filter for the 6.0 engine is reportedly quite good.

Oddly, the OEM designs and even the Ford AIS talked about earlier are all cold air intakes meaning they draw air from an area other than the hot engine compartment. Most of the aftermarket filter systems are an open element filter drawing hotter underhood air. I don't think it really matters how hot the intake air is on a diesel engine since the intake air will be pressurized by the turbo (heat added) and then cooled by the intercooler. I would be more concerned that the "cold air intake" is some sort of lame non-paper element that allows poor filtration to accomplish high flow.

We can argue which filter is better for ever. Its came up time and time again on this site but every piece of equipment I have owned since the late 90's other than my tractor has had some sort of aftermarket filter. MAC or K&N usually. I have had 4 diesel trucks in that time and about 15 other vehicles and never a single issue. I trade most in at around 120,000 to 150,000 miles so they are no garage queens. A few were keep for less miles, and one as few as 18,000 but thats not the norm.

Never had a single engine/turbo problem. Heck, I have not had a valve cover off since 1988. Now I have had injector issues on one truck, tranny issues on another, power steering pump and AC compressor also. But none of these issues would have a thing to do with a air filter.

Thanks for the input. this has a K and N filter. All enclosed. Got a pic of top of motor, looks good. Run Carfax, looks clean, the mileage adds up. It has 149,000. Called ford dealers that have serviced, they have shown no tampering with odometer. The dealers were ones off of carfax listings. looks like a good ride. Will dicker with the guy soon.

Anymore thoughts?

This reminds me of a joke.

Guy is driving down the road and he sees a Cherry GTO with a for sale sign in the window. Anyway he stops and is looking over the car when a man comes out of the house and approaches him. The guy looking at the car ask to take it for a test drive and when the get back he ask what he is asking for it. The man selling it say $25,000. The man looking ask if he will take $22,500 cash. Man selling says he can't do that because its his wife's car. Man buying says well let me talk to your wife then. Man selling says she is at work and will not be home till 6pm. Guy buying says well I will be back after 6 and "dicker" a little. Man selling says that won't change the asking price of $25,000.:laughing::laughing::laughing:

Take the top of the air filter box off and check for dirt inside. Regardless of anecdotal evidence, oil/ gauze filters do allow more to enter the engine; more air, and dirt. Even if they worked well when properly maintained, you don't know how well the last guy cleaned and oiled it.

A turbo for that truck is about a grand, just had to get one for a guy. Wear and damage to cylinder walls and valves is a lot more. If the inside of the intake tube is clean (the part going to the turbo), you may or may not be alright. If you find even a hint of dirt, walk away.

Look at the oil pan. The pans on these trucks have a problem with rust, and rust eating through the pan. Replacement of the oil pan requires removing the engine, due to a frame crossmember that prevents taking it off from the bottom.

 

[Soundguy]

are we still talking about a 7.3 psd? I think that's the first I've ever heard of any oil pan pandemic problem??

soundguy

 

[56FordGuy]

Yes, still talking about the 7.3.

I wouldn't call oil pan rust issues a pandemic, but it is a rather common issue that's aggravated up north where they use a lot of salt and the like on the roads in the winter.

If you do a web search for "7.3 oil pan" you can find a lot of folks talking about it. At one time, I heard someone was trying to design a two piece oil pan that could be installed without removing the engine.

 

[sandman2234]

I have heard about some problems with oil pans rusting, but have never seen one. Must be, as mentioned, a saltbelt problem.

Agreed. When I was a Ford tech we had a bulletin that stated we could void engine warranty on diesels with k&n type filters. Most people don't maintain them at all and the top end of the eingine just gets sandblasted.
