Didn't see that, what about over-tourqued injector hold downs, I have seen guys tighten them with a impact gun and collapse the injector body and they wont spray right? But I guess that would happen right after engine start up.

Haven't seen to many 2004 and up AC ASET EGR engines that get any better than 6.2 mpg. I am working with one guy and we got him at the 6.0 point, just added a high flow Walker muffler and waiting to see the results. There is not just one thing that makes a truck get good MPG it's a combination of many different things that get you there.

Check the air compressor air intake tube that run around the back of the engine to the back of the intake manifold, the short rubber hose could have blown off, it happened to me.

Duralit is the way to go but for small leaks like you had we have some epoxy we use that works good. But if you got the money go ahead and do the Duralite and be done with it.

Heading to Vegas for a week , Mack truck free for 6 days!!!

I vote leaky liners especially if the engine had no coolant filter on it!

It is possible (sometimes)to unplug the speedometer sensor and the truck will run wide open MPH, however most owners/companys who have their road speeds turned down have the MPH sensor tamper settings enabled. What this means is if you unplug the sensor/tamper with the adjustment or any fault occurs with the MPH sensor it will derate the HP and you will be worse off than just leaving it alone.

Thanks!

Thats it, cant seem to find it to buy or download.

Just heard a new song that started out talking about a red Mack Truck, something like "Chickenlights and Chrome" anybody heard it? If so who sings it. I heard it on XM radio Nsahville station. It was pretty good.

On the injector cup issue there are now stainless cups and new style injectors that come in a kit from Mack that will hopefully cure the cup issue. On the gasoline deal, all these trucks were dump trucks that were working in an area far from truckstops, these gas stations would have 4 pump handles on one stand, 3 grades of gas and then diesel. The diesel should have a black cover on the handle/nozzle but we found some stations would have green covers on the handles like the gasoline. The drivers just weren't paying attention.

There is a Mack service bulletin on injector fault codes, dont see many injector failures but mostly the wiring harness connectors at the injectors loose connection. We install new connector ends and this seems to fix the malfunction code most of the time. However as Rasler said the injector cups can cause issues as well. Also check the fuel tank for gasoline! We have had 4 trucks in the last 2 months that had gas in the fuel tanks and 2 were MP's and caused injector codes.

Last I could find of the E6 was in 1990 however in 1991 it still listed EME6-250L and 350L plus the EE6-350, I think these were for export.

Guess I will have to leave my phone in my tool box at lunch if I want to keep going to the strip club!

I agree Rhasler, while Mack/Volvo says their broke and no money to help (policy/goodwill) a owner/operator who has bought an MP-8 and is on their 3 set of injector cups. Volvo show up with this rig, while I like it and it's cool, I too think Mack should use the money to help stand behind their product!

Sorry to hear that! I'll talk to our sales guys. I known your situation and praying for you and your family!

Kilo6 in the shop today, fuel mileage up to 6.1, installed the high-flow muffler, hope for more MPG.

I have a Mack Service bulletin SB214017 that tells all about the wategated turbo on the 2001 (starting in OCT) - 2003 ETECH 460 HP engines. Its a 15 page bulletin and I have it printed but cant get it in a format that I can attach here. I can fax it to you if you have a fax machine? Really you should just put no more that 40psi if air pressure to the wastegate and and it should move/open. Any more that 40 PSI and it could blow the diaphragm. If it doesnt move and you hear air leaking its a blow diaphragm. If you dont hear air leaking and it dosent move it's stuck. Soak the lever with penatrating oil and try to free up.

Very common problem, as long as it goes inactive soon after warmup, I would not change it unless it was under warranty, 2year/200,000 on the EUP's unless you have extended warranty. If it starts staying active for long periods of time then get it changed. 8-2 code means #2 EUP pump. 8 means EUP and the second # means position 1 though 6.

Looks like you got a lift axle on the very back, is this correct? If so, if you crank up the air to it does it help?

The one leveling valve fills all 4 bags at the same time. I have see road tractors converted to dump trucks with air bag suspensions that leaned to one side or the other when loaded. We have installed another air leveling valve on the RH side so that each side had it's own valve so the truck would sit level. But I dont recommend air suspension rears on dump trucks, real squirrly going down the road loaded. Whats your vin and I can look it up, is it the orignal rear suspension?

The Max-lite you have on that CXU seem to be the most trouble-free but time will tell. To me they all are good. You can still get the Mack AL and AL2 on new trucks. It has been around the longest but is heavier and have seen alot of issues with loose U-bolts but that was mostly due to maintenance issues and not the design.
