01_Cummins_4x4

I've always used Fel Pro head gaskets on my gas engines, but not on a diesel before. I made two alignment pins out of two of the old head bolts and inserted them into the two holes in the block with the alignment dowels, so there was absolutely NO shifting of the head onto the head gasket as the head was being lowered evenly and parallel to the block.

Did some research today. The NAPA Fel-Pro head gasket PFG9522PT is only .0610" thick. The stock Cummins head gasket 3977063 is .067" thick. .006" thinner for the Fel Pro gasket could very well have caused some issues.

Well, it's not the water pump. It's leaking out the front between the head and block. I just did the new Fel Pro headgasket, head studs, head was hot tanked, decked, and new valve seals all in the latter part of Oct 2021. just checked the Xotic head studs and they are still at 125 lb ft torque. I did exactly as their instructions say with the lube on the washers and threads, 1st step 40 #, 2nd step 80 #, and 125# torque. I cut two of my factory head bolts and made aligning pins out of them and installed them in the holes with the alignment dowels so that there was no chance of scarring the head gasket with the head. The head was installed using an engine crane and was set down on the gasket evenly. Block was extremely cleaned when putting it all together last Oct. Studs were installed per their instructions of just finger tight. I called Xotic and talked to a tech and asked about retorque of the head studs, and the tech said "if the studs are installed per their steps, no retorque is needed." Now I'm wondering if that's BS and they need to have a hot retorque? My truck has the stock HX35 turbo and I've only seen it get to 32 psi max. If it's just the head gasket, which brand would you go with? There's probably only 3,500 miles on it since redoing the headgasket. I'm really pissed off about this since I have tendonitis in my left shoulder and I don't have the funds to pay a shop to replace the head gasket.

My alternator tested fine but my local NAPA alternator tester can't test for AC Noise, just whether or not it's charging. I picked up a new Bosch type alternator from them for $105 and change, because they have a buy 3 items and get 20% off. I kept my alternator since the core is only $14.30. My alternator has a open groove when it should just be the alternator bracket hole, because the PO didn't tighten up the bolt enough to keep it from moving. This new alternator has its testing slip with it and it shows leakage current at .88 mV which equates to .00088 V. Is the leakage current the same as AC noise?

On Dec 9th 2020 I bought a water pump from O'Reilly's and installed it in my pickup. All was good until last night when it went out. It leaked enough coolant out that the radiator fan airflow splashed it into my alternator and caused it to quit charging. My Edge Juice with Attitude said I had 11.8V when I got home. I found my receipt for the water pump and it says it's a Murray CP7145 and it doesn't fit my 01 Cummins, even though that's what O'Reilly's gave me. The pump they gave me fits a 98 and older 12V. A Murray CP6148 fits my 01 and it has a different pump blade design. The 98 pump has a curved plate on it while the 01 style pump doesn't have the curved plate on top of the blades. Is running the 98 style pump on an 01 the reason why the pump went out? My alternator is the Bosch unit and of course O'Reilly's doesn't have one in stock. I did spray it with electronic parts cleaner and used my air compressor to dry it out. I'm going to have O'Reilly's test my alternator to see if it's dead or not.

@Mopar1973Man Do you know if a 2001 manual 6 speed truck (mine) would run an auto trans with the manual PCM? The auto trans would shift 1st - 3rd, but not have OD or trans temp alert? Sycostang's truck is a 01 but his came with keyless entry and security, and my 01 Sport came with everything except for keyless entry and security.

I can't remember if the Central Timer Module is the only one that controls keyless entry? I don't remember anything about the PCM having any role in the keyless entry aspect of it. We both have 01 Trucks but yours came from the factory with keyless entry, and mine did not. I have since added a Compustar keyless entry alarm system to mine though.

Certain codes can be set without a CEL being on. Do you have gauges for fuel pressure, boost, and EGT?

Use a scanner and check for any trouble codes being set first.

On my buddy's 07.5 3500 4x4, some of his popping was from the front axle control arms, and his intermediate steering column shaft.

Here's my '16 Harley Tri Glide Ultra in Cosmic Blue Pearl (one year color). So far, it has Vance and Hines full exhaust system, Screamin' Eagle stage 1 air cleaner, Power Vision and Target Tune tuner, Legend Suspension front and back, 1.25" rear lift kit, 10" apes, and Harley heated grips. Waiting on my buddy so we can install my Fueling Reaper 574 cams, Screamin' Eagle perfect fit pushrods, Torrington inner cam bearings, and .030" head gaskets. I'm having an Upholstery shop make a custom seat cover for my CVO heated Hammock seat.

I built my 2018 TPC 450X in a week's time. I'm the only person in Oregon with one. It's a 2008 Honda TRX 450ER and 05 Honda CRF 450R combination of parts. It's right at 50 HP and is a blast to ride.

We just pull the clusters out and swap the auto trans gear indicator for my manual trans plate. We don't have to swap clusters at all.

I think you have another vacuum line leak - maybe from the firewall area down to the t-case, or under the hood again. It sounds like when it's cold the break is evident, but when things warm up, it could seal itself up somewhat.

I just put a redhead box on my truck and it was quite a bit better than the OEM stock unit. My buddy bought a blue top and he likes his as well. I've heard Redhead can be finicky when it comes to warranty issues, but I think it's mostly their process to figure out what the issue truly is before sending the box in for warranty/repair. PSC is a lot of money and not having any direct experience with them, I don't know if paying twice the money is worth going that route unless you intend on running 37"+ size tires. https://bluetopsteeringgears-com.3dcartstores.com/2869-4-94-02-Dodge-Ram-1500-2500-3500-2X4-4X4-181-_p_39.html You can send in your OEM (not aftermarket) steering gear and they will rebuild yours into their blue top gear box. The blue top is cheaper than the redhead and probably has better customer service.

That's what I meant about the PCM harness, that it's the whole engine harness which should be a simple swap between both trucks.

Can't we just swap the PCM harness for the transmissions? I know I can flash the ECM with a Smarty and load the stock tune for the manual or auto trans, that's what I did on the 99 Cummins 4x4 I had a few years ago. If both trucks are the same year and have the same ABS setup, could we swap ECM and PCM modules in pairs between the trucks? When I did the 47RE to NV4500 on that 99 4WD Cummins I did, I just flashed the ECM with the manual trans stock tune which gave it the anti-stall feature. I'm trying to remember does the PCM control how and when the auto trans shifts via the electronics in trans? Also, isn't there a trans relay in the PDC that I would need for the auto trans? That's funny as when I was shopping for another Dodge Cummins 4x4, I couldn't find anything that had a verified built auto trans and I wasn't going to take a chance on an auto trans truck off of a car lot, that's why I grabbed this 6 speed truck in Dec 2020.

If I remember correctly the HO has higher compression in the engine vs the SO engine. Sycostang67, I'm definitely interested!

My truck has 197k on it. I bought in Dec 2020 and it already had the aftermarket clutch and hydraulics in it. The only thing I've added is a short throw shifter tower kit in it.

I don't want the ratchet shifter as it would cost a lot more money than just swapping out the steering column and shifter linkages, unless someone was selling a used ratchet shifter for a great deal.

I had my 99 engine, so I'm not totally sure if the 01 stock tune file is the exact same as the 99. A call to Mads would be your best avenue as they would probably know.

I was curious if anyone on here has done the reverse and went from a manual to an auto trans? In my 99 Cummins 4x4 that I used to have a few years ago, I swapped out the auto trans and installed a rebuilt NV4500 that my buddy and I overhauled and installed a brand new South Bend single disk clutch. I kept my ECM and PCM and installed a manual trans stock tune file from Mads with a Smarty and it ran great after that. At the time my left knee had stage 4 arthritis in it and it wasn't liking a stiff clutch at all, so I found a friend that had a verified rebuilt auto trans with paperwork from Baker City, and we spent a long day swapping transmissions and input shafts in the t-cases, and all the other related hardware. I have this 01 Cummins HO factory 6 speed truck now that has an aftermarket clutch and hydraulics (shifts great) in it, and more often lately I'm thinking of finding someone with a verified built auto trans to swap with. My truck has an Industrial Injection VP44 pump, 100 HP SAC DAP injectors, S & B air cleaner setup, Quadzilla tuner, AFE intake horn, 4" exhaust system, and an Airdog 150 lift pump, so I don't want to trade the truck for an auto truck unless the auto trans can be verified fully rebuilt and has the same performance mods that I have in my truck. My left knee has been fully replaced in Oct 2018, but I still cannot bend it past 95* since I have scar tissue that's built up in my quadricep muscle right above the knee joint. My ortho doc said that he could give me a chemical cocktail to knock me out and force it manually to bend further at the risk of breaking something else in the process. I know I'd have to swap trans, flywheel, clutch, hydraulics, t-case, driveshafts, pedals, shifters and linkages, steering columns, TV cable for APPS, and probably PCM harnesses. I'm assuming that I'd have to swap the PCM for the auto trans to shift correctly? I guess if both trucks were 2001 with the same ABS setup, could a person just swap the ECM and PCM modules, or since mine is a HO and theirs would be a SO truck, would that not work? Just trying to get some ideas...

You can flash the ECM with a stock manual trans file from Mads with a Smarty too, as I did that with my 99 Cummins that I swapped a 5 speed into.

When I replaced the heater core and evaporator core in March of 2021. I thoroughly cleaned the inside of the HVAC box. I don't park anywhere near trees and mostly I park my truck in my climatized shop.
