AZB755V8

If still looking there is a Yellow LT listed in Wheels of Time this month. Looks nice and complete for $30k Another "complete" one for $1800 too. Looks to be in pieces though.

That is a real nice dump bed on that wheeled Buro, works real good. Looks like the driver has done that before.

I lived back in the midwest for most of my life so I can relate to Chicago driving. It is predictable. Out here in Arizona everyone is from somewhere else. You don't know what they are going to do but go wherever whenever they want and it is alway in front of you. Even merging on the highway, had a motorcycle coming down the entrance ramp and tried merging in a 100 foot opening in front of my truck at 65 MPH.... Life doesn't mean too much to him, doing that stupid crap, then gives me the Bird. Sort of like a bug that is about to hit the windshield flipping you off. You don't dare blow the horn, people get gun shot out here for being so Rude to signal them to wake up. Road Rage to a whole new level!! Had a guy roll down his car window and tried stabbing my tires with a 6-8" knife at 45 MPH because he wanted in and I just kept moving. I call it Zoning in Zona here, everyone is in a daze driving, everything else is more important than actually driving. Just like the people that run in your blindspot. They come up and pace you but will not pass but stay right there. It is like Ducks and Geese flying in a V the next one is just behind and out of sight, you know they are going to do it... Putting on the occasional turn signal gives them the right to cut in without even looking... in front of you of course... drives me crazy.

I did have air in the lines as well. It took several times to get it all out. It may have been something in the supply line that is blocking flow. We went over most of the things that can happen in another post here, Running out of Fuel, Airlock. It should help.

The last time that is what I did. Disconnected the line going to the lift pump and tank. Blew through it and a steady stream of fuel on the ground. Opened the tank valve and stead stream as well. Maybe there was something just big enough that got sucked in at the bottom of the tank to stop flow and it came out then. looked in the tank and just little stuff the primary would filter out. I haven't had the problem sense. I try to keep the tanks on anything above 1/4 full to prevent crap from getting sucked up. The problem started when I ran it empty. Ran out of fuel about the same time each time. About the amount that would be in the secondary filter, about a quart of fuel, 2 miles worth. Thanks for the help.

That is what I thought too but it still was getting what i think was airlock in the line between the primary filter and lift pump. It did run on all cylinders until the next time it ran out of fuel. I did replace the filters, they had 2000 miles on them and did have some sediment in the primary filter but not much. I need to get some fuel additive as the fuel is starting to smell old. So far it is running like nothing happened without using the primer. It was strange that it continued to run out of fuel for 3 times. I never had that much problem getting a diesel running after working on the filters, pump or running out of fuel. Tanks have working vented caps.

There are a few threads now about fuel issues. I am getting older and the memory is not as good as it once was. Anyway I have a few hobby trucks and only use one fuel tank and drained the other side. So the draw is on the passanger side on one truck the drivers side on the others. I put 20 gallons of fuel in the wrong side and ran out of fuel about 10 miles down the road, I know dumb ass move... I was taking it to a show and it just shuts down. Opened the crossover valves and got some fuel in the right tank primed it up and got fuel though the secondary filter. It took a bit of Ether to get it to start. Started down the road again and in about 2 miles ran out of fuel again. Fuel in primary but not in secondary filter. The primer was not getting fuel and had a vacuum in the line. Left it sit for 10 minutes and it would pump fuel. I filled a new primary filter and put it on. Got it running again with a bunch of Ether. Ran 3 miles and out of fuel again. Vacuum in the primary fuel line again and secondary filter empty. Loosened the fuel line to get the vacuum out started priming it and got fuel though the secondary again. Turned around and headed for home. On the way stopped every 2 miles and pumped the hand primer 10-12 times. It stayed running and did not seem to have air in the lines after that. The question is: If there is even a little air in any of the lines will an airlock develop? I don't think it is the lift pump as the vacuum is in the line before that pump so it is pulling the vacuum. I did blow through all the lines, not collapsed, they were all new 3 years ago. Does fuel plug up a filter from sitting, even in a garage temp between 50-100 degrees, it's in AZ. Running out of fuel don't help and started the problem...

Might be showing my age or that I haven't been to the scrapyard in several years. Last time was with the boy's and showing them that metal junk was worth money when we emptied the piles for the last time. At that time ferrous metal was $200 a ton. Phoenix prices seemed high but my brother in Ohio made Bank scraping a few trucks back then. One was R719-1003, third one built, with a ENDT864 twin turbo, that guys are looking for now, still have the turbos. Wish I had some of that stuff, now it's worth more than scrap price. I think the high was about ten years ago when China was buying scrap ships and filling them with scrap and leaving them float until needed. The point was that this truck was a Great deal for someone that wanted it. Even for just a low milage 865 V8 engine or auto trans...

Glad that was all it was. Yes, they do sound good, like a small block version of an E9. Mine has just a little lope at idle if it is not in 4 or 5th gear and the splitter in neutral, just a little drag and it smooths right out. I like the slow lope only about 50 rpm's difference but noticeable. I didn't have leaking injectors but I have had to weld a few leaking injector lines, no new ones from Mack anymore. They make a mess in a hurry only way I knew was it was loping a little more than nornal... and the big puddle under it... LOL Put that old V8 to work.... just baby it, parts aren't around like they use to be.

WOW that went for $1625. It was worth more in scrap!!!

It is sad too see when a Big Dog gets kicked out of the dog house. It is just a matter of time before it is sent on the way to the pound... How do they keep that water tank from freezing in the winter time, or is this temporary? Sharp looking rig but showing signs of neglect. Hoping for the best but seeing a good old dog being abused. Someone needs to come to the rescue or at least kick the crap out of those guys doing the crime and leaving that Old Dog out in the weather. Probably garaged most of its life... just a crime.

Hope it is the injector. If a head is cracked it will start at the injector hole, and run to the exhaust valve seat. You will see the crack, and can be as small as a hairline or as big that you can catch your fingernail in it. If it goes all the way to the exhaust seat stay away from it. If it is only a hairline that is partial and stops before the seat it maybe OK. This is the same for E9 heads but have two exhaust valves.

First get the injector out ands have it checked at a injection shop. That maybe all that it is.. a bad injector. There is an actual expansion joint in the area of the head between the valve seats. I have not heard of successful welding these heads or E9 heads. When their cracked it is for good and in a bad area by that joint. It is a problem with these engines and if the crack is big enough and goes into the exhaust valve seat, the insert can fall out and hang the valve open... bad for the valve and piston. It sounds worse than it actually is... Just about every 865/866 has at least one or two cracked heads. I went through 18-20 heads to find 3 good ones and one with a very small crack for my rebuild. Some were really bad, certainly leaked and would given a little time drop the valve seats if run hard. If it is a hobby truck your will not be running it hard and could be OK for a long time just putting around if it is a head issue.

The only two things that warrant Ether with a diesel is a lot of blow-by. Even harder to start after sitting or in the cold. The other is a bad charge/ lift pump or the injection pump not building pressure at low RPM's. I have had both problems with some of the engines around here. You can rule out the blow-by because it died just sitting there or after running and warm. The pump is a little harder, Does that rotary pump have a charge/lift pump originally? Sound like the previous owner had the same problem, installing a electric lift pump already. I have been talking about charge pressure in another post. See what the pressure is from the electric pump first. If you got a few PSI, then it's you injection pump. Both may be gummed up from sitting, is there any way to run some cleaner through it on the engine? Worst thing have the injection pump worked on if you can find someone. I has seen in a photo a 1 1/2" hose with plug under the dash of a B so the driver can give the engine a shot of Ether from inside the cab. It would work... what else would it be for.... LOL

100psi oil pressure is a little high but with additives is realistic, too high and you can blow the filters off the engine. As long as you don't go below 30psi hot things are OK. Just make sure you set a high idle of about 800 RPM's to warm it up good. and get the pressure down a little. The only seal on the bottom of the injectors is a copper washer, most times they can be reused or I have anyway. Hope it is just the injector. Not to scare you but if you are getting fuel up around the injector it maybe a cracked head. These older V8's cracked a lot of heads. The crack runs from the injector nozzle to the exhaust valve seat. I know, went through a pile of heads to find 4 good ones for my 866 rebuild. Real nice truck... Real nice

Need to run them a little more.... or at least idle them... LOL

There should be some maintenance records on that truck somewhere. Check the original dealer it came from. Even if it was owner fleet maintained they would have records. Just ask the seller for the record for your reference and maintenance cost, shouldn't be a problem...Right. If I remember right I bought a 93 CL700 with 17,000 hours and 390,000 miles. It was a local oil field truck and didn't seem too far out of line. I know the Speedo was correct from the records, avg 23 miles per hour. Ran good the great oil pressure.

I heard that if the charge pressure gets much more than 100psi it will blow the secondary fuel filter right off the engine. I just replaced the gauge to see pressure. That filter is just like the construction of a oil filter and seen those blow off at 120psi. That would be REALLY bad hanging right over the right exhaust manifold. Still would like to know the range that the galley pressure should be. Know so far 20psi seems low and 100psi is too high. I got a 13mm pump as well that has been worked on. It does return a lot of fuel to the tank. I could only see it running out of fuel running wide open maybe, not normal driving. The engine has only 12,000 miles on the complete rebuild and all lines were replaced then, 1/2 inch to and 3/8 from pump... but could still be bad from sitting. Looking back at when it was missing and spitting. I had below a 1/4 tank of fuel and was getting on it. The fuel pick-up is in the lower front bung hole in the tank. From what I have seen a lot of fuel is running out and into the tank. Probably got all the fuel to the back of the tank, accelerating, and was sucking air. Guess I have to have over 1/2 full tank to go drag racing or change the pick-up, I'll change that when the truck is restored in a year or so. A working gauge would have shown that I think.

Thanks, I'll have to get it out on some deserted road out here and wick it up. Any place else the Fire Dept would be called for the smoke...LOL I did exactly what you said with the gage already to make sure it was not something in an old line, it is wire tied up by the windshield. The pump at idle really puts a good stream back in the tank, plenty of flow. There would be a point that the volume of fuel will not flow through the valve and pressure will rise. I have the govenor RPM's raised so the charge pump should keep raising pressure, good point. Maybe the miss and stubbly was due to old fuel that I did drain already. On the PT pump Cummins pinching the return line was the 2 cents way of putting more fuel to the injectors if I remember right. Not the right way but drivers did it to get more power. More than a few burnt pistons and valves I am sure.

I've been having an issue with my E9 Superliner. It starts and runs fine and if just put around don't skip a beat. If I step it a little, blow a little smoke, it noses over and start missing and sputtering, like running out of fuel. I get out of it for 10-15 seconds and it recovers. It ran Great before being garaged for 2 years. Now issues and I want to take it cross county this year. Getting to the point it has a fuel pressure gage, broke since I got the rig. I put a new gage in it today and got 20 psi. I wonder if too low and putting air into the injector lines. This gage reads galley fuel pressure, what the charge pump is putting to the injection pump. The broke gage was stuck at 80psi. So I took out the return restrictor and took out the copper seal ring and got 30psi. it seems that this part is losing the spring pressure over time. Have any of you had experience with the return restrictor going bad? My thought would have been the charge pump but it is returning a steady stream to the fuel tank even with the increase in pressure. What is the the normal galley pressure for a Bosch pump. I don't think it is different for V or inline E9 pumps.
