Now hopefully your down time is limited.

Like yesterday I was working down at Rapid River for the Fire Dept. I got there at about 11am at it was getting hot by about 2pm in the afternoon my PanaPacific gauge showed that it was 113*F. By 8pm when I was getting ready to go home it was still 107*F.

More than likely... If the connection was poor and it gets out of range then the code will pop. But like myself I'm still using the MPG fooler yet. No issues.

Most hidden air leaks occur on suction lines. When if it's a pressure line it will show up with any pressure as fuel would leak out.

Next time I stop in Riggins I'll ask the Chevron station on the filter number he's using so I can post it up.

Ummm... Diode would crate that issue. Diode is nothing my than a check valve for power. It can only follow in one direction so if you hook it up one way you'll have hi volt code and reverse it and have lo volt code. But now a resistor of proper value should not trip any codes because the computer see the proper range of voltage.

Edited out the personal info and provider. (Thanks AH64ID) I tend to want to give provider kudos but can't. But the thing is like he says this truck is going to be used in the back country crawling around the hills. As for me doing the work I'm not worried to much just this Rancher wants to do his job without be stranded in the mountains. No worse than buying one of these truck for a Fire Truck and explain to person "Sorry your wife died in a car crash because our fire truck had to Regen" or "Sorry your husband died from a heart attack because the ambulance had to regen to the your house". This is real. Like my fire chief is looking at a extremely cheap fire truck extremely low miles (3,000) but they have to sell it because of the regen problems. But do we want to buy into those problems? Actually there is a lot of shops I found that will talk about it but the requirement is that the owners sign a document saying its not for on-highway use and the truck leaves on a trailer. Beyond that its up to the owner what he/she does beyond that. Simply put it... Everything we talk about here is technically illegal. Modification of fuel systems, larger injectors, turbo changes, modify timing curves, changing computer software or programming, retrofitting different engines into different trucks, removal of the stock air filter box, even my own MPG fooler is illegal because its altering a smog device (IAT information). Even my Edge Comp on documents states for "Offroad use only". Like WhiteLightning p-pump conversion is illegal. So basically if you install any device to your vehicle that is not OE then your basically doing illegal action against EPA or CARB depending on where you live. So I'm suppose to worry? Show me a completely stock truck here that is unmodified... Might find one...

This project will be done here at my place so lots of pictures and maybe some video. So lets hope 4th July does not go off with BOOM! Because fire threat is very very high right now. I've on stand by for the fire dept right now.

City of Riggins, Idaho is going to hold fireworks display this year... Crazy? I think so...

Something Aden set me up with... Yes... I'll be doing the job most likely after the 4th July. Parts will be here on the 1st of July.

Parts are on the way for this project. Owner just purchased everything. (Moved to 6.7L forum)

Up here in Idaho there is several places that are going to reach above 100*F mark today and the next few days. Then on the other hand please folk be careful with the use of fire. Also please take the time and look over your vehicles and fix any leaks you have. I've just seen a nasty vehicle fire that was a total loss. It could of been cause by leaking fuel or engine we'll never know but lets work together to protect your vehicles and families from harm.

The whole fuel system weakness is the VP44 at the center. Basically there is 4 ways of killing a VP44... Fuel lubricity - Bosch states in there own testing that all fuels should be at <450 HFRR but US fuels are about 520 HFRR. Fuel pressure - Dodge FSM states a minimum of 10 PSI. Unoffically we state a minimum of 14 but no higher than 20 PSI. This is to hold the overflow valve open. Fuel filtration - Extra filters or better filtration is always better for life span of parts. Power - Yes even the VP44 is sensitive to AC noise as well and should be less than 0.1 AC Volt measured at the BATT post on the alternator. CSM is right this is just a old school 727 trans in these truck with a electronic 4th gear. The problem is that the 727 and the 47RE are designed to handle max torque at higher RPMs but like the Cummins it create high torque in low RPMs and the pump pressures are not high enough during these loads. Hence why people change valve bodies, add pressure and modify the governor pressure signal with a resistor. I know Wild & Free could spit out the newest transmission model and it would be a huge upgrade over the older 47RE and 48RE.

I highly suggest just asking Edge Products for replacement wiring loom. A cut up wiring loom is trouble waiting. Might also time consider upgrading completely.

Kind of like the Weather Tech Floormats JAG1 got me... Really nice not to have to vacuum the truck all the time just shake the mat out once in awhile. As for your cup holder its a automatic I've heard all the horror stories about them. No worse than the early 2nd gen cup holders high on the dash. They suck too. Now mine in the 02 truck I love because even a 1 liter bottle fits in the big holder. I might have to pick on up for the 96 Dodge though...

Mine was the compressor front seal but you'll never see the dye being its inside the pulley. But before you do all that I would try getting a cheap $11 seal kit at NAPA and reseal the entire system. It'll take about 1-2 hours to do. Then put a vacuum on the system and leave it overnight to see if the vacuum holds. If not you still got a leak. Then I would consider the evaporator and/or compressor.

??? I guess we need to create a article of this.

If ordering a radiator I would order one for a automatic transmission so it had the proper cooler fittings. The best suggestion is to pull the radiator and take it down to a radiator shop and have it pressure tested. Then you'll see exactly where its leaking.

Yeah... Angus not to confuse you but White Lightning (Ryan) converted to a p-pump on his truck and they tend to like more pressure. On a VP44 truck 14-20 PSI is optimal pressure.

That's my problem. I've got the exhaust brake hanging off the back of the turbo.

That's an damaged compressor wheel. So in your case I would inspect the air filter and just replace it. As for the oil I still say to pop test the injectors to be sure.

Also be aware of your offset and width of rim will change the diameter and profile of the tires so it can impact odometer and speedometer accuracy. It will be small but its there like my truck with the change of wheels and tire size I've got a 0.5 MPH offset. Small but its there and can't be calculated but it can be measured with a GPS.

Sad part is this thread has so much good information about engine building but will most likely get lost in time. I wish you guys would start creating even small article about this. Like the piston differences that is so cool to see this kind of comparing of parts and how they work.

Well the turbo is destroyed like mine was. The compressor wheel was destroyed by a hose clamp. So mine sucked in that debris of the damaged blades. So in you case I'm not going to say the sky is falling but its time to investigate a bit more and figure out what happening. Oil dilution is cause by failed injectors. That can be checked by doing a pop test of thee injectors. Not a turbo issue. But debris issues could cause a compression issue (blowby). So compression test would verify that problem. Since the injectors have to be pulled to be pop tested you could do a compression test too. Another thought is wastegate issues? (sticking open)

It was solid debris that struck the compressor blades. So there was either debris inside your filter or a hole has been rubbed into the filter.
