2nd Generation Dodge 24 Valve Powertrain

It is suggested to be done at 135K miles which I think is too far down the road. Mine where out of adjustment a bit at 92K miles. So this is how I did my valve adjustment on my truck. Valve adjustment is fairly simple to do and does require much for tools. You need a feeler gauge set (0.010 and 0.020), 9/16" box wrench, 10mm short socket, 15/16" socket, both 3/8" and 1/2" ratchets, Allen wrench and a mirror. The first thing you need to do is pull the valve cover off the engine. You'll need a 10mm short socket and a 3/8" ratchet. Loosen all the bolt till you can lift the bolt up. Don't bother removing the bolts from the valve cover. Once you got that the valve c…

Problems with the stock breather... This is a home-brew fix to a problem on the 2nd Gen Cummins engines. The problem is the OEM crankcase vent is nothing more than a piece of hose mounted to the front of the gear case that elbows over and points down towards the ground. There is two versions of this. One is with a drip bottle mounted on the end of the hose and the other is without the bottle. In any case there is a TSB (09-002-02 Crankcase Breather Overflow) warning on extreme loss of oil from descending to steep of a slope while off-roading. This is true but it will also scatter oil all over the engine and radiator. This cause a second problem of overheat from dust and…

Carter Campaign Pump 4090046 Cummins Part Number $63.00 Dodge OEM Pump BSAAL6429X Mopar Part Number $209.00 Napa OEM Pump NFPP74213 Napa Part Number $179.99 Carter Fuel Pump (Generic) P4601HP $99.50 Carter Campaign Lift Pump This is a redesigned lift pump for the Cummins engines. From what I heard it was design for the Buses more than anything. But I found that the Campaign pump is exactly identical as the Dodge OEM pump that was supplied at manufacture. Just much cheaper in price! UPDATE - November 24, 2006 The campaign pump is doing fair with a stock engine configuration. My fuel pressure have slid a bit and now it idles at 13.5 PSI, Cruise at 12.5 PSI, and WOT 1…

UPDATE! - July 18 2007 - Cetane What is it? What does it do? I'm still seeing a large amount of people that want to continue adding cetane boosters to the 2 cycle oil this is not required. Today diesel fuel is approximately 43 - 47 cetane number. Please check over on the MSDS page. Cummins Cetane Requirements for 1st, 2nd and 3rd Gen Trucks A Cetane rating of 40 is recommended at temperatures above 32 degrees. A Cetane rating of 45 is recommended at temperatures below 32 degrees. There is no benefit to using a higher cetane number fuel than is specified by the engine's manufacturer. The ASTM Standard Specification for Diesel Fuel Oils (D-975) stat…

UPDATE! May 19, 2007- 2 Cycle Oil And The DynoJet... Well there has been a lot of talk about 2 cycle oil hurting to HP/TQ numbers. Well I'm here to set the records straight for once and for all... First off let me lay down some baseline information. You all have seen my web page on my BOMBs and MODs I've done. Ok... We all know that the 2002 Cummins SO is rated for 235 HP 460TQ at the flywheel. Run #1 - Stock mode with Edge Comp Turned off. 228 HP - 462 TQ Well this proves there is very little drag between the flywheel to the rear end. Also this proves there was very little improvement in HP/TQ number concerning 2 cycle oil. I'm using conventional D…

I would highly suggest that no one uses 2 cycle oil in a vehicle that is already designed for ULSD. These engines have some very expensive equipment on board like diesel particulate filters etc. These device are not cheap to replace. Also remember this might or will VOID your warranty on your truck. These engine have been redesigned to be run on fuel that are very low in lubricants (Sulfur content).

For starters my lowest temperature around here was recorded at -20.2*F (-29*C) on January 16, 2007 in New Meadows, Idaho. This was recorded by my on-board thermometer which hold histories of HI and LO temps for both inside and out. During this entire season I never use a single anti-gel product on the market. Just diesel fuel and 2 cycle oil.Now remember above in the specs sheet for ULSD the gel point is 0*F.Now think about it. A snowmobile runs on a mixture of about 40:1 to 50:1 gasoline and 2 cycle oil. This very same snowmobile must run in extreme temperatures down as low as -40*F (40*C) and maybe lower. But what I want to point out here is... There is no problem with …

I found some interesting document about the way that diesel fuel is shipped and I'm going to share these document with you... http://www.arb.ca.gov/regact/dieslub/notice.pdf <- Some information on how diesel fuel is now shipped. http://www.arb.ca.gov/regact/dieslub/hor.pdf <- More on how diesel fuel is handled. http://www.ncagr.com/standard/diesellub ... r11504.pdf <- How North Carolina is handling diesel fuel. Basically diesel fuel after being refined is well above the 520 HFRR rating which is unacceptable by any standards. So its up to the delivery personal to add the lubricant package to the truck before delivery. Currently I cannot find anything that insu…

I'm still researching products and more research I'm doing the more I keep finding that diesel additive are using mineral spirits, xylene, naptha as a anti-gel and/or certane booster. But remember these chemical are NOT lubricants. I'm also finding that some of the chemical that they are using in fuel conditioners are cancer causing and have high health hazards. Like I told one user on Cummins Forum I've got a whole gallon of Xylene in the shop for paint thinner but I won't add that to my diesel fuel!We are trying to find additives to add to our fuel that contain lubricants and not thinners. With the on set of ULSD and lack of lubricants it has the last thing your injecti…

More Information on ULSD... First, I want to concentrate on the loss of the sulfur and why this is important to you. Sulfur is an Extreme Pressure (EP) lubricant. It is regularly added to lubricating oils and greases to increase the lubricity and to raise the amount of pressure that the lubricant can handle before the lubricating molecular barrier begins to break down. Sulfur has always been a vitally important factor in providing lubrication to diesel engine fuel pumps, fuel injectors, and to a lesser degree engine valves. The reduction now being made takes on-highway diesel from less than 500 ppm to less than 15 ppm, which for all practical purposes eliminates su…

Introduction I've been adding 2 cycle oil to my diesel fuel for the last about 20,000+ miles. So far I've found out that it has improved a few things like engine noise is reduced, fuel mileage increased slightly, and knowing the the fuel system is being lubricated is always a plus! I've been adding a quart every time I fill up with fuel. So if I pump 20-25 gallons I'll add a quart of 2 cycle oil. It makes it roughly 80:1 to 120:1 ratio of fuel to 2 cycle oil. This is relatively low ratio and with not cause any harm engine as far as I known. There is another reason why I'm adding 2 cycle oil to my fuel. It because of EPA changing the sulfur levels in the diesel…
