  1. I have been chasing a poor running '05 C.E.G.R ASET for week's while doing other repairs to the fleet. It acted like a bad lifter... I checked everything, there were 3 EUP codes, so the owner had me replace all EUP's, Injectors, and Fuel lines.. It ran better but was still exhausting "Eye Burning" rich exhaust... I loaded the new version of P.T.T. into a New laptop, and tested everything I could,, everything I was doing including PTT was pointing at #5... I ran the valves....twice... fuel filters etc. We sent it to Mack to have them do a compression test, because our shop doesnt have the tools. (we ordered them)... Mack says #5 has 100 PSI compression.... so today I'm pulling the heads... the last thing I removed was the intake manifold, and guess what???????????? Ive only been doing this 23 years,,, and this is first for me.... W.T.F.? I can laugh at it now, but trying to explain to the owner that I'm stumped! before I found this was a bit stressful... Of course no-one will fess-up about leaving a rag in the intake and cranking the engine... 🙃

  2. at one point I had the c.a.c. out of the truck. My guess is one of the body shop people put a rag over the c.a.c. pipe and then mabey someone else jumped in and fired it up... But still no-one is speaking up, of course all of the other guys don't speak english very well... just glad no one is chewing me a new A-Hole... The heads are at a machine shop getting a valve job... It's all good..... Joey

  3. Joey, not a problem at all. I did find a shop not to far from me. Getting prices on recoring it or repairing it. Trying to see if its worth trying to fix ourselves since my brother is able to braze. We did mange to get the radiator out of the truck last night. Bushings were shot after 34 years lol, so going to replace them. just don't want to spend a couple thousand on a new radiator especially since the truck isn't used everyday or as a work truck. Just a project truck.

  6. I saw that one time with a cat.When who ever found it some one had at the paint shop let a hand full of paper get into one port like that.I think the paint shop had maybe some of the engine apart.

  8. Looks like a good show with good weather and a good turn out. Little too far for me to travel, but I hope he did well.

  9. I found a NEW inline E9 pump and the topic strayed to Hot Dogging Macks and such. So this topic is about getting the most out of what you got, not just keeping the old dog barely alive. To start I Love BIG Power, it comes at a price but with these Old Macks is so EZ to Have. Not for everyday working truck modifications but for hobby trucks and occasional outings to take the old mechanical dog on a "Run". This topic will not be for all but will be useful information all the same. I finally got some space and time to pull out the Tank Quad Turbo set-up that I got some time ago. In preparation for this I was looking for inline E9 injector pumps. To start the NEW E9 Pump was damaged in shipment. Fed-Ex Said that claim was to be files by the shipper. Pump came from Italy so not hoping for a lot. It has to go to the pump shop for repairs so.... Lets get it Turned-up. Thinking 20% on fuel and 20% on the governor. This will be a Hot road engine maybe going in a MH Ultraliner that is out beside the shop, only has 118,000 original Km on the ticker. Along with that I got a pump or two that I got over the years to put on the calibration machine just to see where things are at. (2) 12mm, 13mm & 14mm shown. Power start with the pump and you got to know where things are at to begin with. Now the Tank Engine set-up. Mocking this up today on more than likely the engine that will be rebuilt to handle the power output that this set-up will deliver with a 14mm pump and a little "Secret" stuff. No shifting required with this set-up, as manual trans do not shift well over 2500RPM's. Trans is the bullet proof cable shifted, no electronics, Allison HT750CR Automatic. There were only a very few E9's with Automatics orders only by the US Military and I believe they were HT740 Allison's. Lets talk, Hot Rod Stuff, From the other post 300bar injector pop-off is higher than Mack spec but it works better for fuel atomization it is 50bar higher than Mack spec. About every 25bar the engine timing needs advances 1 degree, 2 degrees for 50bar.

  10. Cool! Thanks for clearing me up. Honestly I was close to feel myself knowing everything about old US trucks and that wig-wag literally knocked me directly between my eyes

  13. The boost will be there. The Turbo technology since these engines were built has come light years ahead. The Garrett turbos on the E9's normally had boost in the low 20psi and narrow RPM range. Todays turbos will make 65-70psi and a broad RPM range. The Single Turbo on the Superliner made 60psi and spooled up at 1800-3500rpm's then just starts to fall off up to 4000rpm with the old Holeset. Now with a new Borg Warner SE500-91 it is 65-70psi, gauge needle bounces a lot. 1200-4000rpm range. Think I now need liquid filled pressure gauge? Look close on the hood to see the Superman E9-1200. That is NO Joke and the power is to the ground. The flywheel HP is 1500 from the Mack engineers specs/recipe that it was built to. Pump was done at Antrim Diesel years ago. This is with air to air into a water to air intercooler. To the right that is a 91mm Holset T5 that is long gone, number 8 cylinder dropped and ate a valve seat in Cleveland, went though the turbo, and kept on rolling into Phoenix 2000 mile later on 7 cylinders still passing just about anything on the road. Of course there was a "little" extra smoke form the stacks. Heard about it a few times on the CB, I just said give me five mile and you will never known I was there. The boost that I will be OK with is 120psi for the Tank engine project. The engine will spin at least 1000rpm over the 2500/2600rpm military governor so stock turbos may not get it done before running out of air. The truck this is going in is a MH Ultraliner for a few reasons. The engine will be moved back about 2 feet to where the frame narrows. Engine will still be under the cab. The reason is the turbos will hang down on the outside of the frame rails and not interfere with the front tires or steering. I will have to angle out the turbos to get the clearance with some custom wedges between heads and manifolds. No frame alterations except making it a single axel from the Canadian spread tandem it is now.
