If you shoot me your VIN, I can see if there's anything I can help with. I occasionally see miracles every now and then! Volvo has issues with keeping anything in stock, much less parts that commonly go out. Imagine how you'd feel when the dealer you just bought your brand new truck tells you they issued a recall but parts are at least a month out! Or taking your SCR equipped truck in for an MIL only to learn they updated the DEF Level Sending Unit to require a pigtail that's more than a month out!

You're right, it's the oil supply line. Just be careful with the o-rings on the two nipples on each end, unless you match up with a kit from a parts/hardware store, they only come on the piece themselves. Most of our techs end up requesting them, but I doubt most jobs NEEDED them.

I will say it's been a while since I've quoted a short block for an ETECH or older, most of our customers have been asking for overhauls lately. Maybe there's something I didn't know...

I'll I'd have to find a VIN or part number for one, we don't see ANY E6's here. I know from past research that Mack still makes E7 rebuild kits/short blocks, usually per order. I've used PAI for smaller parts a little bit, Lippert as well. Automann has been the most helpful for me lately.

I completely forgot that the air compressor has coolant lines running to and from, goes to show I'm not that experienced! I don't recall that happening to any trucks in the shop, but we've had a bad air compressor that got misdiagnosed into an entire short block R&R... I'll chime out for now unless someone needs some help with parts...

My job is usually pretty boring, as I'm a shop parts salesman. I exclusively handle parts for our shop "technicians," so I thankfully never have to deal with customers on the front counter. We still have our own frustrations don't get me wrong... We've seen some crazy failures before, from a previous owner running exhaust manifold studs too far into the block, destroying two pushrods, to a roadside service (that Volvo uptime called for the driver) botching a wheel seal job and ruining both spindles, hubs, and brakes. Fun stuff. EDIT: I somehow skipped the part about bad parts people: It can go both ways, but usually leans to bad training on the company's end. My training was being put next to the older guy that was a wealth of knowledge, no actual company training at all. If I didn't have a brain for it, I wouldn't have been able to keep up.

I GREATLY prefer Cummins over any other lookup. It actually makes sense and, like you said, actually has a functioning search. The only issue with Cummins is the Aftertreatment Device section, but that's because the OEM never sends them what device was installed at the factory, so Cummins lists all the available parts. At least Impact will show those parts, but Hino/Isuzu couldn't care less.

Haha, I still respect my elders, I was raised that way. I can't imagine watching a prestigious brand like Mack get dragged into the dirt by a European truck maker. I agree that Impact can be really bad (nowhere near as bad as looking up UD parts, that company is an abomination), and the majority of parts guys are lost most of the time. I like to believe I stand out from them however!

There absolutely are! I found this forum trying to research parts for an older E7 ETECH one time, and kept coming back since. The forum was extremely helpful in giving me info while researching the Jake assembly on a different ETECH. Lots and lots of amazing information here.

Was going to suggest EGR cooler, but that apparently won't be a problem for you (Very smart of you). We've seen oil cooler/side cover failures before on both 11 and 13 liters, that could very well be your issue. I also wouldn't discount the possibility of the head gasket leaking, but we rarely see that at all.

I don't exactly want to make it public, but I'm not super far from you. MP's and mDrives are absolutely my biggest money maker, that's for sure.

Hey ya'll, I've been lurking long enough I figured it was time to make an account. I've been a parts salesman at a Mack dealer for 3 years now with 3 years of Mack fleet technician experience prior. For the past 3 years I've been working as the shop parts salesman here, which flowed nicely with my previous experience, and has enhanced my knowledge and love for old Macks. Sadly, the oldest truck we've had so far has been in the early 90's, but my love for the days of semis long past keeps me invested in the field. That and my ever-increasing hatred of Volvo and the bastardization of the Mack name. Yes, a 26 year old is allowed to have good taste. I'll try to browse the Parts Wanted section to see if there's anything I can help with, but unfortunately my resources only cover trucks that are so old. Anything to help the cause!

I'm by no means qualified, but it sounds like your SCR might be dead. Pretty much every truck with 4094 that rolls in our shop leaves with an SCR. There were some times new NOx sensors resolved the issue, but most resulted in the truck getting a new SCR. Did you use an OEM NOx sensor? Most aftermarkets we tried ended up not working, to the point our shop won't use them at all.
