Yes the truck I seen was a CL. I just went back to look. It said CH but was a CL 

Ok I've had enough of this motor in my 2004 CH613. I'm not putting anymore money in it. I was looking at trucks for sale this evening and I ran across a 2007 CH with a ISX Cummins. So the more I got to lookin I found more macks with the isx cummins. Does anyone know where I can find the wiring harness that goes from Mack to Cummins. 

Ok thanks Jerry, I did the one piece tank but still running the 16psi cap. I will grab a 10psi this afternoon and give it a shot. Honestly I'm to the point of thinking about pulling the motor and dropping a early 90's Mechanical motor back in it. 

Lol yeah I understand I'm not to far from Atlanta and Spent to much time in those pubs myself. I just replaced the Y looking hose going to the oil cooler and mine didn't have a screen in it. I pressure checked the coolant system and found a few cold water leaks, once I fixed those the system didn't leak down. I just installed a new cap and going to pull some water out of the tank. 

Get one thing fixed and something else happens. 2004 CH started pushing coolant again. Had this problem 3 or 4 months ago and ended up being EGR cooler was cracked. So I did a pressure test on the cooler and it was good. I moved on and replaced radiator cap, still doing it. I capped off coolant lines going to air compressor and it's still building pressure. You can remove the cap off the tank and throttle the engine up and it will push the coolant out of the tank. I have replaced the 2 piece tank to the one solid tank. This truck is going to be the death of me. 

That's guys for all the input. Find the problem it ended up being the peanuts in the front drive. Placed them with new bearings and the sound went away. 👍🏻 Seems like I get one thing fixed and it's something else. Smh truck just started pushing coolant. 

Sound like say there was a bolt and something was hitting the head of it every time it makes around.

Yes, I can only hear the tapping nose at low speed. 1-6

T310 transmission started making a knocking sound. At 20 mph at a coast you can hear it pretty good. You can pull it into neutral and it stops. Hoping someone knows. Thanks

I've been wondering the same thing. I would love to do my 08. 

The truck runs fine but the regen light flashes all the time. It will not regen at all going down the road. You can set the parking brake anytime and it will do it. Not showing any codes.

Dual exhaust, I will check them just to make sure. I've even changed the ecm. First I put a 380 hp still the same, 427 hp same and the 460 hp same. I couldn't tell any difference from the 380 to the 460. 

It's like something is smothering it. When you leave a ref light it takes for ever to get up to speed, and if you ever let up on throttle it want recover you best off drop a gear 

Nope sure don't, we plugged in computer at dealership and it was showing 32 psi under load but not sure how accurate that is. 

At 1250 rpm it's showing 68 and it calls for 50-80 psi. Truck has gotten weak over the last couple of months. It's got new turbo, intercooler, injectors and Mack has checked the Egr valve and said it's work fine. I'm clueless and tired of throwing money at it. 

I've heard from a few folks that you can shim the plunger to create more fuel pressure. Does anyone know if this will work? I just replaced mine on a 2004 AC 427 and the pressure is still low. 

Vanes are sticking on my turbo, can you buy replacement vanes? 

Ok thanks for the info. 

Just installed a new rear head on my AC 427. Got it all put back together and was running overhead and had a problem on #4 Jake adjustment, with the screw backed all the way out I could not get my feeler gauge in between actuating pin and the piston. I had no problem with the others. Any help would great. Thanks 

Ok thanks 

I've got a 2004 AC 427 that swallowed a intake valve. What is the difference between the E7 head and the AC head? 

What does P5098 M128 01 01F mean? It's staying active. 

Has anyone done a delete on there MP8 that's been successful? I've talked to one place in Canada and they have takin there's off line bc they've been have to may issues with it. 

That's on the to do list for the weekend lol

I wonder if there's anyway to up the fuel pressure
