The Heinz

Oh boy, I hadn't heard of that. Doesn't sound like the best idea, since my pickup already doesn't let me regen while in park supposedly because of the exhaust temperatures. Let's go ahead and make the already blistering hot exhaust even hotter!

Diesel is slowly going down around here. As of this morning, it is $4.76 at the station I prefer to fill up at, but stations all over are clinging to the $5 range. Better than before, but still a long ways to go...

It's infuriating and just plain sad that it's getting more common, and is just being pushed harder and harder by all the tech corporations. Youtube is just about unusable without any adblockers now, you get nonstop ads on nearly every video now, and the videos that show up in your feed are usually trash. Facebook is full of AI generated content, probably because the average user doesn't have the same tech/internet experience as someone closer to my age, making it easier to trick them. Everything on the internet as a whole now is intended to attract and capitalize on your attention, and it blows. Spending less time on the internet and more time in reality is much, much better for us as people, I can promise you that.

My favorite videos when I'm in the mood are KT3406E's. That guy is a wizard with Cat motors and is honestly hilarious whether he intends to be or not. His most recent video about getting two 3406E core engines to run after buying from a mine wholesale was really cool to watch. If someone out there posted videos of similar but with Mack, I would absolutely follow it.

That's the kind of news I needed this morning, glad to hear it!

I forget how many there are under there, it depends on the year too. There were usually two part numbers, one ending in a 116, the other 118, that were for different PSI's. My helpfulness kind of comes to an end there...

Happy birthday Joey! Hope to see you at the truck show in Spencer May 9th!

Never driven a semi, but I bought a used Cobra 29 LTD from a yard sale for dirt cheap, and got a truck stop special whip antenna and cable job; mounted the antenna to my crossover box like the previous owner of the box had. Ended up taking the radio to a shop in Knoxville, TN while on a trip since it wasn't working, and got a new mike and tune up. Felt like a real man driving out of the truck stop the shop was in and hitting it up for a radio check, and getting several checks back. I never really used it a whole lot, and the whip got old since I was dragging it in the drive thru line, but it did come in handy on one trip down the I40 gorge to TN. A trooper had pulled a rig just to use his radio trying to redirect traffic away from 40 because a massive hole had opened up on a bridge. I was too far from 77 to jump up that way, so I got sent on a backroads journey through rural Appalachia that to this day I have no clue where I actually was! GPS wasn't working worth a darn, and of course I don't have a physical map, so I just used my noggin and got to TN without I40 lol. The CB quit working years ago now, I've been wanting to redo the setup now I have a different truck and a greater appreciation for trucking, maybe I'll add it to my ever-increasing list of things to do.

Could be brake demand switches by the brake pedal, had several instances where they would fail and cause similar symptoms.

Yeah, I won't be much help anymore. My contact at the dealership isn't as savvy at finding parts for modified Macks like I was...

My 80+ VIN list strikes again! Try old number 48RU2341, new number 25152307.

I sent the part number to my buddy at the dealership, maybe he can find the number for you. No luck, maybe with a VIN but the old Mack support has left with me...

The cams are different, I remember there being different cams for no-engine brake, Jacobs/JTECH, and Powerleash.

I'll have to make another rain check this year. Been wanting to go, but it's just too far out of my range to easily handle and would cost more in fuel than I need to spend right now.

I will say that I did see a couple 1990 model trucks with E6's from the factory, I have a couple VIN's saved on my Old Macks spreadsheet. One is a Candian 1990 RB690SX with the EM6 300 in it, the other a 1991 RD688SX with the E6 350. Your truck may have come with that E6 stock.
