Well, one,new oil pump later and the oil pump drive gear has become unpressed from the shaft........Dernit!!!! It's at the shop!!!!

820,000 miles and geez I can't remember the hours. This summer was rough on the old dog. I spent most of my time in Louisiana and heck I doubled my normal hours between service cuz of idling. APU for sure next summer. I don't mind the cold but can't stand heat...

Well, I took the oil pump apart....There were what looks like small pieces of piston ring inside that really chewed up the one impeller. The screen on the pickup was bent up leaving a gap for foreign objects to get into the pump.... Well that explains my oil consumption increased lately. Looks like the inframe plans for this winter are gonna have to happen...... I don't see any real damage to any of the liners or piston skirts though.....

Ok, pan is down the pump is out and it will only turn 3/4 turn and lock up....The secondary drive looks ok... If I could just keep the oil from dripping in my eyes...

Greetings gang. I just finished changing the oil in my 03 Vision with the e7 427 in it. When I turned it over I heard a loud crack, and the engine started and ran but no oil pressure. I lifter the centrifugal filter cap and it was dry. Did I just break and oil pump?? The engine sounded normal, and I did shut it down after about 30 seconds. I pre fill my filters and such. What has to be done to check the oil pump and how is it driven? THANKS!!!!

My feeling on these re-flashes and chips and such is if the engine was designed for something like this the factory would have done it.....Maybe.....I had a buddy that did a reflash on his series 60 Detroit and within 2 months he had to do an inframe because 2 of the pistons came apart. He was lucky that he didn't ventilate the block.... The only way I would consider these things is on a fresh rebuild....Just my $.02

I add 1 gallon of Lucas when I service my 03 CX with a 427. I started using Lucas when I had my 95 CH with a 350 in it. I ran that motor to 1.5 million miles and it finally blew a head gasket so I pulled the motor. There was wear, but we figured we could have run it for a while longer if we wanted to repair the head gasket. I just figured that it was time to update.....I have the opinion that the Lucas does help. Right now I have 766,000 on my 427, and it's running 60-70 lbs oil pressure depending on the temp........

I have a Webb 650 fuel filter/heater that is getting a bit old. The FS1029 is the only element that comes with the correct bowl gasket but the o-ring that come with the filter doesn't fit. I have been using the old o-ring for quite awhile and I'm afraid that one of these days it will rip and I will have to replace the entire setup. My question is this. Does the fuel have to be heated??? There has been an ongoing argument around here over fuel heaters. My opinion is the cooler the fuel, the better the injectors will like life. Others say the fuel should be heated to flash correctly. I'd just as soon disconnect the coolant lines to the heater. Also, I've heard some of the temp controls in the filters go bad and the fuel is basically at 180 to 200 degrees. That can't be good........

Any thoughts??????

well wasn't that pretty badly designed there mr mack. i finally got the filter out and it was nasty. maybe if the engineers designed it a little better it may be cleaned more often. just a thought. anyway many thanks to forum for the info.

Aw come on!!!! It wasn't that bad!!!!! It's also a good time to stick the cupholder in the dishwasher and clean out all of the spills!!!!!!!

The 9 speed in my 95 ch did the same thing.The syncros eventually went out. I put a reman trans in it and ran it for 8 years with no problems, and that was local work. lotsa lites and stops. My shop told me it really helps to wait until you are going as slow as possible before downshifting into the low box, such as rolling up to a stop sign or lite........

Lets not forget the new fuel we have to use now! its shit!! no matter where you are!! bobo

Speaking of the New fuel, I started using Howells or Power service once a week in my '03 CX with the 427. It's a pre-emissions engine and I swear you can feel the difference!! I don't have a boost gauge or Pyro yet to really know for sure. I was going to add the stock gauges but it sounds to me like too much $$$ and pain in the tailfeathers.

Thanks guys!!! Heck my brain went into neutral and I didn't even think of that idea for the boost gauge!!!!

Hey gang!!!! I've been trying to add the stock Pyro and boost guage to my dash cluster. My truck did not come with them. I see no plugs anywhere to get the pyro sensor cable into the computer or wiring harness. Also, I have no extra hookups out on the engine for the boost guage. I'm I at a lost cause??? My dealer has been trying to help but has struck out. I'm about to give up and go to Teltek for the aftermarket units. But, they are EXPENSIVE!!!!!

The Vision hood is more aerodynamic. You'll get better mileage!!!!!!

I have an '03 vision with a 427 and it's pre emissions and I love it. I have a buddy with an '04 460 and he has had some troubles that he has been told were the first year blues for the emissions 460's. That plastic radiator tanks seem to be a sore point. Mine has a cold leak around the top tank and his had the same trouble.......He is getting around 5.8 or so out of his 460 pulling doubles with a super 10. Doubles do eat up the fuel!!!!! I get 6.4-6.8 at 63 MPH out of my 427 with a straight 10 speed and 3.70's

Rob, I certainly hope you get to feelin better. I know what it's like to have a cold just gets you down!!! One time I was blowing up Nellie and I sneezed and it took me an hour to fix the split seam in her side.....By the time I was done I wasn't in the mood...........

Oh yeah, nice hat!!!!!!!!

Greetings and welcome to the group!!!!

What trans and rears do you have in your truck???? A lot of times gearing will fool you into thinking you have no power. Also, driving style will have a lot to do with it as well. The Mack will wind up, have a completely different RPM range and feel than the Cummins. I went from 435 Detroits into my 350 Mack and it took some getting used to but it wasn't too long till I was comfortable with it. Then I got my CX with a 427 in it and I had to do it all over again!!!!!!!!

Oh yeah, don't use Mapp on a propane head......Different orifices and you may not like the results..........

That will only release the bulk of the air from the cylinder. The bleeder screw is placed at the highest point of the fluid cavity as to facilitate entrapped air rising to that elevation to be removed by "bleeding". As you will remember from elementary physics: A fluid medium, (liquid) cannot be compressed. A gaseous medium, (air in this case) readily compresses to many times it's atmospheric pressure/state.

Hydraulic power is based upon the principal that a liquid cannot be compressed. This lack of compression allows the movement of fluid under pressure to perform mechanical work. In this case, ultimately spreading of brake shoes to provide friction against a brake drum.

Wait a minute......Will the person using Rob's identity please untie him and let him go!!!!!!!!!!

Did you mean connecting rod? Anyways, 3500.00 seems like a good price for a nice superliner.......

WOW!!!! Great cleanup job for only having it 2 weeks!!!!!! Did you eat or sleep at all in that time????????

Dogs no matter what the breed are good on a spit after scraped from the road in winter. Best left for natural sunlight to do the cooking during summer in the name of energy conservation.

Rob

Yeah and lately they are pre salted and really crunchy!!!!!!!

Kool!!!! Real Kool!!!!!!

Mack has been testing SCR for several years. The shop that does my heavy work does the service work for the factory test trucks. I happened to stagger in there one day when they had one in there. What a mess of sensors, plumbing and stuff on that truck. It was a Vision with a 460.

The scuttlebutt is that SCR will use about 15% EGR VS 30% or more without SCR. That seems to be the issue. Get that EGR reduced to bring back fuel mileage and dependability. Also, a whole new industry will be developed.The DEF (Urea) will need a distribution system ETC......

Of course, we could all get Rob to pee in our DEF tanks................

Rob, Please don't let the superficial efforts of your wife to get you to bathe more often get you off track.......Stick to your guns man!!!!! All of the males of the species are counting on you!!!!!!!!!!
