Yup just sayin Heinz! oil in coolant just Sayin Heinz ! makes more sense to have Oil in coolant ! That said shit happens!

In the past, we had some failed EGR coolers causing oil and coolant to mix, I wasn't sure how that happened but it went away with a new cooler kit. There's no telling if there was another problem that reappeared later but wasn't brought to us though.

The internet as a whole has improved a lot for society, and this is but one way it has. The modern freight/shipping situation is on average so much better than how my parents and especially grandparents told me, the internet being partially responsible. The downside of the internet is how distracting it can be, but that's honestly more of a social media problem than "internet." What I wish is that people would understand that a part being a day late (making it two days' worth of waiting) is incredible, where not that long ago it would have been a week before we got it. I remember as a kid having to ride everywhere with my dad trying to find one specific thing because online ordering wasn't exactly a thing yet. Human progress is incredible isn't it?

Vodka was first made in Connecticut ......1916 Smirnoff building demoed in 1997 Heublien also made steak sauce

Yup that is correct. Turned out to be that the leveling valve didn’t even have a deflate port. Someone must have changed it and not put the correct one.

I haven't played with it yet but I think the 2 speed might be an underdrive. I'll have to shift it and see what happens next time I drive it. Some of the logging roads in the Olympic Mountains were quite steep and the original engine wasn't much over 200hp (215, maybe?). He added a turbo a few years after he bought the truck then it stayed like that until the 400 went in about a year before he retired. The Alcoa wheels were also added quite late.

Alternator is reconnected and working correctly. Thank you again.

It will look a lot different once paint is on Paul

Probably quad box with a 2 speed brownie behind it for more top end … very common back then … Bob

They got priorities baby !!!!

If your in melbourne australia i can do it for you.

It was less than 10 years ago, I didn't have trouble finding drums for my spokes, but haven't tried recently.

Hi Everyone, As those who have been following my Mack Quantum rebuild thread know, I am a bit OCD when it comes to quality and reliability. Running out of money on that build actually pushed me back toward my professional roots—I have over 20 years of experience in electronics. Recently, I have been diagnosing and fixing complex ECUs and controllers that other repairers gave up on (mostly for mates running French car wreckers), maintaining a 100% success rate. That experience made me realize there is a massive gap in the transport industry for specialized, component-level electronics support. I am looking to pivot into the heavy transport sector and am launching an on-site ECU and controller repair service here in Melbourne. What I offer: On-site Diagnostics & Repair: Fast turnaround to minimise your fleet downtime. Advanced Fault Finding: Pinpointing complex, intermittent ECU-related issues directly on the vehicle. Component-Level Repair: If it is not completely encased in solid epoxy resin, I can likely fix it. What I am looking for: I want to partner with a few local mechanical workshops. In exchange for your collaboration, I am offering a permanent, exclusive discount rate on all future repairs. Initially, I just need two things from my founding partner shops: Dead ECUs: Core units that are broken or deemed unfixable by others, so I can map common failure points (and most likely fix them). Sensor Access: Permission to hook up a scope to running trucks to record clean sensor signals for my database. During the initial rollout, complex repairs may take a few days while I scale up my local parts inventory. Once fully stocked, the goal is same-day turnaround for 99% of cases. If you run a workshop or fleet in Melbourne and want a reliable, on-site electronics partner, please send me a PM or comment below. Let's chat!

I would keep an eye on this! Still could be cups! Just sayin! The connection doesn’t add up!

Just thought I'd update with the solution, turned out to be a failed EGR cooler.

When I just got all the brakess and bearings for my 1980 Louisville they told me at the trucks parts store "don't screw up one of your Dayton hubs because it will be cheaper to convert the whole truck to budds" Luckily I was able to get all the parts I needed. They found the drums in Toronto and the brake shoes and hardware kits in Montreal. The bearings and seals were still common.

I can wait in line for a new T.V. I can wait in line for Pokemon cards I can wait in line and cause a riot for a $400.00 Swatch... NEXT ??
