Every state needs to learn the law enforcement that he provides, and Do It !!

Yes sir, i am thinking the guide pin is jamming the lifter in the bore, and may need to be drilled out with an 1/8" left hand drill bit to use an easy out to rotate and pull the guide pin

Did the EUP roller rotate? Which cylinder is it?

fjh is right. when you remove the sensors from the venturi you will see 2 little ports on the pipe and the sensor. be careful not to scratch the pipe when you clean the soot out. you can wet the soot with brake cleaner and try to pick it out gently. It is a dumb design and it WILL clog again.

I bought that truck when I worked for Mack. I have a few others, even an 'R' Model tow truck with an American Flag design. I think you have the same one.

So for a while now I have been a CDL trainer at work. I am currently working with 1 employee. He's doing good, so for fun I thought I would give him a Birdseye view of his slow maneuvers course. As you can see, I only use the Best tools for this illustration.

So... many years ago i chased this issue. I could drive the truck fine around town at low RPM's. I would get on the highway and at about 1600 RPM's or around 22 + PSI of boost, the truck acted like I shut it off. It would dump boost. It was the new boost sensor. It was the wrong part number for that VIN. turns out there are a few of them and all of them have a different voltage range on its 5 volt circuit. The one in my case was 1.5 volts (if I remember correctly) different than the correct sensor. Its been about 17 years ago.. Maybe Heinze can figure out the part number, and Mackpro is great with these sensors and such..

Ive been at the top in spring time and it was snowing. What an amazing place.

Yes.. Has the boost sensor been replaced recently ?

Those 2 guys really are the reason we are where we are today.. Really... they revived racial bias and hatred...

Thats the sadness within.. todays youtube truck drivers are cluesless

Its all around here. The local dirt haulers all sit on the floor and reach up to the roof to shift.. Im surprised that the stick doesnt shift for them when they let off the throttle.. at leatse in to nuetral..

Luv it..

After you put that shifter in, you can also remove the air bag from your seat..... You wont be needing it.. 🍻

Well i got the van back together. The test drive was a success. I would post a video, but the engine runs so quite, you wouldnt here anything. Me thinks it had an intake leak as well as the coolant leak. The new vacuum lines didnt hurt either.. She got : intake gaskets Valve cover gaskets Thermostat Coolant sensors Vacuum lines Blasted and painted covers And a water pump The serp belt was in grsat shape. The radiator should have gone to get boiled out, but....
