That looks like what I want to do with my Vision. I found an all mechanical 350 with less than 100,000 0n a Remack job at a good price but I don't know how many hosses it will turn up to.

bigen I would play like I never saw it. The experts say it doesn't belong anywhere in the engine so I'm thinking it was dropped in by accident and fell down an oil galley while the cover was off to run the overhead. As many miles as you've run by now I'm betting you're safe.

keeping a couple old farts on the strait and narrow could be a full time job.... yeah I wish him luck cause I need all the help we can get.

Yep people do some mean things. I bought an old truck years ago that kept starving for fuel in a pull. The injector pump checked out fine so on further investigation I found grease rags and rubber balls in the fuel tanks stopping up the pickup. bigen's screw may have fell straight through while the covers were off to run the overhead.

Cummins is too long. I noticed an ad wanting an offer for a 673P here at BigMack and the 673P is bullet proof and will tweak up real good. http://www.bigmacktrucks.com/index.php?showtopic=12447

bigen I thought about your truck today when I was working on my water system. I was adding a new line for aux heater on the trailer and decided to look at my screen. That danged thing was so stopped up it had collapsed. I run a water filter and had serviced it when I pout the new water pump and housing on, about 2-3 weeks ago. It was funky with some kind of red grainy looking muck. It must be something that came in from the trailer system. Now I'm going to engineer some sort of in-line filter for the trailer. Thanks for bringing up this screen subject.

when I replaced #5 gasket I loosened the manifold nuts on the other 5 cylinders about half way. Then I put double nut on the studs for #5 to use as a stud puller and take the studs out of that hole. Then I slid the manifold out against the nuts and drop the old gasket from #5 and slide the new one in. Then I put the 2 studs back in and tightened the manifold back down to specs. I didn't have to loose any injector lines or anything else. If I were to replace #4 gasket I would have to drop off the EGR mixer tube but that's only 2 clamps. It won't work like that if you have heat shields or something in the way but it worked out fine for me as mine has no upper shield on the rear half of manifold..

yeah buddy. When I was in my 20s I was herding an Emeryville with a great big old 220 Cummins and a 5 speed over with 2 speed rearend. Then a B61 with 673P and triplex, then a H model with 673 with a 9sp Mack overdrive. When I got up to a cabover Pete with a 270 Cat and 5 X 3 I thought I was the cock of the walk.

I'll check mine. A leak sounds about right. Since Houston has never been right on anything else they've repaired I better take look into this for leaks.

bigen every turbo that's been on my 460 screams loud. A shop guy at Mack in Houston told me it's the waste gate that makes that noise. I don't know what it is but it doesn't effect my power or fuel mileage. I have to agree with you it's fun to turn loose a bull dog on a large car Pete or KW. Some of the sidewalk sissies can't stand the pressure. I loaded in Chicago Wednesday evening at 3pm and unloaded 6pm in the Alamo on Thursday. That's no new speed record but it's alright for a one eyed old fat man. I'd have done better if I didn't get so sleepy down by Neelyville.

I don't find over just a few speckles in it cleaning that often. I see the bulletin MackPro posted says change it so I guess I'll start changing at least 1 per year. I change my differentials and tranny oil every 100,000 to 125,000 and rotate my tires every 50,000. I use centramatic tire balancers all the way around and haven't had a cupped out tire in a long time. I don't know if it helps but I feel better doing it and usually I don't have much trouble selling my old truck when I decide to trade up. I'm back in the Windy trouble free again. How's your new ride doing??

welcome aboard spud . I look forward to hearing about your Macks

the first time I cleaned mine it had about 300,000 on it and looked like it had been used to sift red dirt. I cleaned it then and started cleaning it about every 6 months no matter what mileage. If I use green coolant I have to add PH treatment but if I use the red Conoco antifreeze I've never had to use additive for PH. I think maybe Conoco red must have additives already in it. I like to flush the system and use new every 6 months. My buddies say that's too often to service but that's okay. I grease my truck every week and change oil at 10-12,000. I think antifreeze and grease is cheaper than parts.

That sounds more like you're thinking out loud than rambling to me bigen. keep it up. I put the plate back in mine and it's doing fine. When the EGR cooler cracked cost me about $1300 and it hasn't cracked another since I put in the plate. Mack has washed their hands of the 04 problems and left us to die so I'm going to keep Obama engineering on mine until something gives. I got another no trouble round under it's belt this week. That's about 9000 miles since a belly-up so that's a new record for it. hooray One day I might get brave and try an ECM for a E-teck 460 and throw all the pollution crap away. I keep watching to see if someone here has done that before but haven't seen anything. If all I have to do is switch the ECM I'd do it next week end.

According to the machine shop the turbo had a bearing seize up. No reason for it, it just happened. The new turbo is doing fine. I've got almost another round in with no probs.

No on the tank, they kept being on back order at Mack so we put the update thermostat housing and bottom radiator hose and static fill hose on but left the old jugs in place. HK that might help too so thanks for the idea

when I figure out how to post it I'll post a picture of my "coolant pushing" cure. After putting a new waterpump and housing on mine it started pushing coolant again. I had the cylinders and heads checked and they found no problems so we didn't know what else to do. I went to the boneyard and got a 2.5 gallon steel coolant reservoir from an older Western Star because it is round and looked easy to modify the reservoir brackets on my truck to fit it. When I installed it I only filled it halfway with coolant to leave room for whatever and put a new 7 pounds pressure cap on. So far on 5500 miles or so it hasn't lost any coolant and never over pressures the 7 pounds radiator cap. I've been driving it like it belongs to my mother in law and I'm mad at her. damifino why but I think it's fixed.

I think so too bigen. I think my Vision is overall the most comfortable truck I've ever been in. Now if I could just make a round or 2 without a $1500-$2500 breakdown I'd be a happy camper. In the early 70's I put a 250 Cummins in an H model Mack so I know with the right cutting tip and the right duct tape this Vision might come into a 60 series Detroit this summer..

That's right. I've bought a lot of good manuals from ebay shopping. http://shop.ebay.com/?_from=R40&_trksid=p3907.m38.l1313&_nkw=mack+repair+manual&_sacat=See-All-Categories

Yeah I thought the binding was just part of life and it's never been real real bad so when I caught this post I tried the Dextron. If you and MackPro keep posting I might get my mess in shape to make a round trip one day without another bank loan thanks guys.

Thanks for posting the update MackPro. My manual says to use the same 15/40 oil in steering as we use in engine so I've always used Delvac 1300. I've always had a slight bind on left turns but with the Dextron it's smooth as glass again. Thanks again Jerry.

I tried the turbo swap once bigen but when I put the old style turbo the engine goes to "limp home" mode. Maybe it would work if someone knew how to re-set the ECM?

I have an 04 Vision with 460/18sp. The Vision is by far the most comfortable truck and I like it more than any truck I've driven but the 460 Mack engine is the most unreliable contraption I've ever owned. I bought mine with just over 200,000 miles on it and soon discovered why it looked so clean and had such low miles for it's age, the owner before me simply could not keep it on the road. I listen to fjh he knows what's up. If the bugs are worked out of it you've found a treasure.

me too. The top plastic to metal seam separated on my factory radiator so I installed the all metal from Detroit Radiator. It does great.
