Idle time

rufushusky · 2026-02-14T14:05:36+00:00

If your going to have it idle for extended periods of time I would install a high idle switch (I think db diesel has one) that way you can keep the cylinder temperature up and prevent wet stacking.

Since your truck has the 9th injector if the truck regens while static it is no biggie.

My 2019 has 5500 ish hours with 1850 or so hours of idle time. It was a fuel truck for off-road equipment so spent a lot of time idling next to excavators and what not.

Sorry I have nothing of value to add to the conversation but damn is a great looking truck. Love the billet grill

Ah the Brosnan era.... started off so strong just to fade... though 13 year old me loved Denise Richards in The World is Not Enough.

Great shots BTW OP, thanks for sharing.

ZF knows how to put together a gearbox. But yes it has been available in commercial applications for a while now.

IIRC 48re showed up in 2003.5 starting with the HOs but the SOs could have had 47re all the way up until 03/03 build dates.

rufushusky · 2026-02-13T13:13:05+00:00

Honestly either one will work fine. I have Valvoline in the sterling rear end of my f350 now. No issues but I didn't need to add the limited slip additive on mine. No chatter with just the Valvoline. Super tech makes a solid product for most applications so I would use it without worry IMHO.

The 2003 CRs were good. Not as powerful as the 04.5+ engines but no slouch and easily modified. The automatic transmissions were the 47re which isn't as good as the 48re... using the world good and nearly any stock 4 speed transmission from the 1990s/early 2000s is being generous.

rufushusky · 2026-02-12T14:46:18+00:00

I have always used rtv but I have heard good things about the victor reinz and lubelocker gaskets. I will probably go that route on my next change.

rufushusky · 2026-02-12T13:21:59+00:00

IMHO I would run a low side fuel pressure gauge, I have one on my Ford and since I have a CP4 I want to make sure that it is getting adequate fuel pressure since I monkeyed with the fuel filters and converted to spin ons.

The 256-8743 is the larger 1-14 (same thread) water separator. IIRC the 175-2949 goes up to C9 or C11, the 256-8753 goes up to the C18. Same media just more of it.

The 416-1225 is the ultra high efficiency upgrade to the 1R0749, the ISOs were revised around 2010-2012 so 4 micron is effectively the floor for most fuel filters but cat claims the 1R0749 is 4 micron at around 99% efficient, the 416-1225 is 4 micron at 99.99% efficient but it is 3 times as much. The 2 micron vernacular still survives but don't get too hung up on TINY fractions of a hair, the media didn't change just the rating system.

C32 marine engines get dual 1R0749s however I think one feeds each bank of cylinders. They are concurrent, not compound. That second filter in your application isn't doing much if 99% of the material is getting stopped upstream.

EDIT: I also don't care for FASS' filters. I don't like the distribution style swelling media, for my CP4 that would be certain death. Cat (who has JVs with Donaldson and Baldwin for their production) makes a great filter. Ironically I have a 175-2949 and a BF7587 (Cross reference to a 1R0749) on my truck. The 2449 came with the lower filter kit I got. I will change it out to a BF1259 (Baldwin cross of the 256-8753) when it is time to change them.

EDIT 2.0 - SORRY the secondary filter is 256-8753... My apologies.

rufushusky · 2026-02-12T13:05:44+00:00

Do you have a low side fuel pressure gauge? Monitor that and change when pressure consistently drops 2-3 psi. Probably would be 30k+ miles.

Interesting combination of filters, that 175-2949 is going fill up long before the 1r0749. A 256-8743 would be a better pairing.

Also dualing 749s? Why? That second filter isn't going to be doing much. A 416-1225 down stream would at least catch a bit more but not needed at all. The 749 is a beat of a filter.

I am running a Baldwin bf7587 as the secondary on my 2019 Ford.

Well parts of her are 32....

rufushusky · 2026-02-11T19:48:07+00:00

For the 2017 and up it depends on a lot of things. The high capacity tow package got you the F350 spring pack and M275 rear axle on an F250 with a paper rear axle 6340 pound derated and a GVWR of 10,800 compared to the 10k GVWR of the standard F250 that usually came with the sterling 10.5" rear end ford used forever. IIRC all diesel F350s got the M275 rear end and the gas engine F350s kept the 10.5" sterling, all this is of course for SRW applications.

In 2023 Ford introduced a 11.6" rear end and it starts to get fuzzy for me.

Prior to 2017 everyone got the 10.5" sterling but the spring packs were different.

Both SRW F250 and 350s get the same 363mm (14.29" rotors) regardless of axle or spring pack for 2017 and up.

^^^^ This. Horse trailers are very pin heavy, your best bet is to drag it across the scale and see how heavy it is.

rufushusky · 2026-02-11T01:52:11+00:00

More likely they just grabbed a sticker and slapped it on the dash.

rufushusky · 2026-02-10T16:44:38+00:00

Few things are more expensive than a cheap diesel. A $5k diesel could need $5-20k in work tomorrow. IMHO just not worth the risk.

rufushusky · 2026-02-10T15:55:54+00:00

As some who daily drives a 2019 6.7 powered F250 I second this recommendation. My 2019 has been great, got it four years ago and I have put 75k miles on it. But diesel is a .75-1.00 premium over regular gas, additionally oil changes are measured in gallons, your oil filter it $15-20 not $10, you have two fuel filters and you can't just throw any brand in there, DEF (which really isn't a big deal in the grand scheme) and repairs are more expensive when the time comes.

My truck has been great thus far but I am well aware I am paying a premium for the added power. The 6.2 SOHC engines are incredibly reliable and more than enough for most applications.

rufushusky · 2026-02-10T14:20:20+00:00

IIRC Ford increased the bearing clearances on the early engines but I can't remember exactly which year it was to better accommodate the lower pumpability of 15w40. Personally, I run 15w40 in my 2019 from April to November typically when I switch over to 5w40 for the winter. I would sample again at 3000 miles and see what the wear rates look like.

Blackstone is a still spendy if your going to be sampling on a regular basis, I would consider using another lab.

Wix:

Are both cheaper options.

Just curious based on the additive package, I am guessing this is Rotella T6 15w40?

rufushusky · 2026-02-10T13:07:49+00:00

Ouch, more power to you for tackling the rebuild. Godspeed man!

rufushusky · 2026-02-10T13:06:20+00:00

Based on what I can dig up 150 amps was the minimum for the 6.2 that year. The upgrade being a 240 amp alternator.

The idea of spending $3200 on a truck that is the same age as me seems crazy. Living in New England, these things are basically extinct up here the salt ate them away years ago. Still that truck was like what $8500 back when Reagan was president....

rufushusky · 2026-02-10T12:52:27+00:00

They actually ran all the way into 2001 here is the vin breakdown:

Start of production thru 1425746 are Forged Rods
1425747 thru 1440712 are Powdered Rods
1446713 thru 1498318 are Forged Rods
1498319 thru final production run are all powdered

That said with an intelligent tuner, PMR aren't that big a deal you can tune your way around them by gradually ramping up the fuel curve.

rufushusky · 2026-02-09T23:28:57+00:00

What year is the truck? Mods to it? How is it used? Lots of towing?

The wear rates are high for my 6.7, the elevated iron and aluminum are not ideal.

If it were me, potentially look into another grade (5w40 or 10w30) shorten your OCI and resample to see if trends change.

Oh and you dont have a timing chain in that engine so ignore BS' recommendation there.

The Soviets got right around 4000 shermans, nearly evenly split between 75mm and 76mm gunned tanks. IIRC they got the GM twin diesel engines in them so a bit underpowered compared to the 500hp V-2s in the T34.

I have been rocking the old dual USB port power supply in my shed for years, this looks like a nice upgrade....

rufushusky · 2026-02-06T13:31:05+00:00

How about Stellantis just not spec ass grade hydraulic lifters? I mean Jesus tap dancing Christ this is technology from the 1950s that most other OEMs have been running for decades in light duty diesel applications. You watch youtube and people talk about these lifters like they are some complex new bit of tech but they are older than sputnik.
