    What happens when fuel gets contaminated with water?

    This thread has became quite educational and a good read. Like already stated and then stated again, keep the water out of the injection system. That being said, I will also say this, I live in probably the most humid, most water-logged, most foggy, state --- Kentucky; I currently have...

    Why No Turbo Whistle

    I can never get used to the low boost PSIs related to the IDI set-ups. When my truck still had the 6.9, my old Hypermax, exactly like the one in Mel's picture, would easily push the boost needle above 15-PSI The 6BT can fast-idle and show 5-PSI, with 40-PSI easily acheivable, easy enough...

    What happens when fuel gets contaminated with water?

    At our shop, I have a clear glass bottle with about four inches of diesel and about two inches of water to which a few drops of red food-coloring has been added. This bottle has been a great conversation piece for several years. I can really shake up the bottle until the red-colored water...

    Why No Turbo Whistle

    Turbo whistling has more to do with what style intake is attached than the exhaust. Some turbos come equipped with silencer rings that stop the whistle; 1991.5-1993 Dodge/Cummins Holsets for example. It also has a lot to do with how free the turbine spins and how easily it coasts when no...

    truck dies after filling tank

    These sight-unseen diagnosises are somewhat tough to pinpoint; but, I am going to make a stab at what I think is going on, given the evidence available. Everything is fine until you poke the nozzle in there and stir up the dregs in the tank. Something, maybe even a floating grease-rag, is...

    Yesterdays 435 Mile Haul

    I see you have ceramic coated pistons; how much heat can they stand as compared to stock ?? Stock 6BT pistons are safe at 1250* continous and can withstand short duration spikes past 1450*. I just wonder how many more degrees American the ceramic coating would add to maximum safe EGTs. :)

    Yesterdays 435 Mile Haul

    As for the smoke issue, that is one big advantage to the Bosch VE pump; it has an infinitely adjustable aneroid diaphragm with a fuel-pin. The lack of such has always been the down-fall of turbo-equipped IDIs. If there is a "smoke screw" on an IDI pump, I have not yet located it. With...

    >>> 1700 I-H WIPERS ??? <<<

    Is there a forum such as this site where mid-80s International trucks are discussed ?? First on the list is I need a bit of wiper motor and switch information. We ?think? the truck is a 1986-model 1700-series. I haven't yet got it to be still long enough to investigate; but, when I got...

    Fuel Selector Valve Nightmare

    I will say this about electric tank switching valves --- I have never had one myself that was trust-worthy and I am better than most about disaster prevention. I do believe that the absence of any means of filter/screen protection is cause for probably 50% of the failures. Working at the...

    vacuum help

    One other thing : It is just good business to install a permanent vacuum-gauge inside the cab. Equipped thus, one can pick up on situations much quicker/easier that trying to trouble-shoot with a hand-held gauge. Of course, the hand-held gauge is still necessary for isolating the pump...

    Fuel Selector Valve Nightmare

    You just made me remember that I got a whole bunch of those antique-tractor glass sediment-bowls that would be ideal for such a purpose. I need to have someone smarter than me to list them on E-bay or somesuch.

    vacuum help

    I forgot to add : It matters not where that can/chamber is located, so long as it is connected to the system via a vacuum line. It could be mounted inside the cab, taped over a head-light, or zip-tied onto a trailer-ball and it's function would remain the same. A capped bumper...

    vacuum help

    Cut and plug the line that goes ONLY to the can; do this in such a place that you can splice/sleeve it back together if the problem is not the can. Once the can's line is plugged, see if the problem goes away. Myself, I would not fear temporarily driving the truck minus the can; it serves...

    vacuum help

    My 1985 has a soft-ball-sized black plastic ball-shaped vacuum reservoir instead of the paper-thin rust-prone pork-and-beans can. Like already said, that can is a vacuum reservoir that ?might? allow one more assisted brake application. Your process of elimination that you described will...

    Sub Forum Idea

    On another site I frequent, the E-bay and Craig's List threads got so plentiful that the site owner completely banned the practice. To keep things in line, post such items once and you get a warning plus the posting gets deleted; do it a second time and you are automatically un-requivocably...

    looking for better ac performance

    The wife's truck, 1991 Dodge/Cummins, had a properly operating vacuum-controlled heater-hose shut-off valve. The vent temperatures on a 90-plus day would hover around 50*. When I discovered that these factory-installed vacuum valves DO NOT CLOSE COMPLETELY, I dis-carded it and installed a...

    looking for better ac performance

    Do you know which injector-pump you have ?? If your injector-pump is a rotary Bosch VE, it is a very simple matter to replace the governor spring. Various governor springs are available including 2700-RPM, 3200-RPM, 4000-RPM, 5000-RPM, and even 6000-RPM. Factory-issue on a 1989-1993 1st...

    slantnose chrome parts getting the blackout treatment....

    The bright yellow truck actually looks better with the black accents. On the same note, my 1985 chromed plastic trim is all milky and faded, headlights, above and below grille, and around the windshield. How can I restore it to better than factory-new; as in, how can I make it look like...

    Elkectric fuel pump rated for diesel fuel

    There shouldn't be anything in a Holley Red or Blue, nor a Carter (my preference), that weird blends of diesel would harm any more than they would harm the injector-pump, so long as that fuel is CLEAN. The base has a gasket and there is an O-ring that seals the pump-shaft on the Holley (a...

    >>> SUBSCRIBED THREADS <<<

    Over the years, I have subscribed to a number of threads, such that I can refer back to them whenever necessary. Before the site got "improved", I had no problem finding and accessing my subscribed threads by simply going to my "control panel"; which, if it still exists, I sure can't find it...

    Steering Box swap on the road?

    I am going to have to dis-agree a teeny bit with the popular (and respected) wisdom and say that lower tire pressures are gonna amplify your problem instead of helping things, ESPECIALLY with flimsy Michelins; they will squirm all over regardless. Like already said, unless you have been...

    CL - 84 ford f350 7.3 diesel (Burkesville Ky)

    Burkesville is a pleasurable 40-mile drive from me. It is almost the land that time forgot. We have always said that one should reset their watch back 40-years when entering Kentucky and 60-years from that when going to Burkesville. You will still see wringer washing-machines on the...

    Dana 70 or Sterling 10.25?

    When I need to know such things, I first ascertain the part-numbers for both inside and outside bearings/races of BOTH hubs in question. If the numbers match, then it is almost a sure thing a swap is easily do-able. If the numbers do not match, the next step is to procure a set of bearings...

    f350 frame, what to do?

    Regardless of the stiffness/flex factor, a boxed frame will rot out in short order. Many smaller trucks and SUVs have boxed frames and, after a couple years, you can poke a screw-driver through them just about anywhere you try. Being in the tire-shop business, I am under all makes/models...
