anybody got a 2000 k 3500 4x4 dually?

[hauling8]

i have a 2000 k 3500 4x4 4 door 6.5 turbo diesel. anybody else got that year?

[SCREAMINXL]

no, why? My friend has a 98.

[bigde53]

I do 2000 k3500 crew cab 4x4 8ft bed single rear tires.
Got it in 2002 with 40k on it now has 114000. Never any problems other than a new PMD at 90k.

I have a 98 3500 4X4 and I am soon to be pulling about 15 to 20k 3 car hauler on long hauls are you have any problems is there anything I need to look out for?

Fill out your signature. What mods have you done? Have you re-worked your cooling system? Do you have an IC? A reflashed PCM? A TurboMaster? Gauges? Is your engine S or F code? What rear end ratio?

Pulling 15-20K is not a job for either the faint-of-heart or the unprepared... this is large weight for a 6.5, and if you go out on "long hauls" with the wrong set-up, you won't be back.

FWIW, I pull a 9800 lb fifth wheel and I have done all the above stuff. It still works hard at it when I see hills.

I pulled 9800 before I did the mods, too... it was a nightmare, and I'm experienced enough (and patient enough) not to kill the truck while doing it.

i changed out my 4:10 gears and put 4:56 gears in it and a air induction kit on it and thats it. i pull heavy load of roofing shingles all day long. i have 207000 miles on it as of today 9-5-07 and still runs like a champ. no more mods.YET

I just bought a 2000 diesel 6.5T , 4x4. I put my cabover camper on it and it sets low in the back so I am putting airbags on it next. I just had the cat removed. I have a boost gauge and it only registers about 3 lbs with my foot in it going up hill. It hardly moved before I took the cat off. I suspect I have turbo problems. Can anybody tell me how to tell if it is the turbo?

[grancito]

There are two tubes going into a rubber connecton to the waste gate solenoid, track the tube back from the waste gate. Pull the rubber thing out and you can put one tube into the other side to connect them together. Try it carefully, you have direct connection from the vacuum pump to the waste gate, your boost should go 15 psi plus, don't let it go so high, tells you there is no problem with vacuum pump or waste gate or waste gate controller.

[surreysinner]

15PSi plus? ;p Anthing more then 15psi ur looking for trouble with an intercooler.

Are you kidding. Mine stock would get 5-7psi tops. Now i get around 13-14 heavy foot.

[grancito]

Sure, it could blow the head gaskets, thats why I said not to let it get that high, it is just a quick test to rule out faulty vacuum pump, wastegate contoller and and wastegate. Mine reached 14 psi during this test with a light foot.

Sure, it could blow the head gaskets...........

That cracks me up.... The poor quality of these motors is disgusting.......

The Mercedes OM617 runs the same compression ratio (21.5:1) and the same boost (9-10 psi, no intercooler) in it's stock form as the 6.5 GM...... but several folks have put different turbo's on (or just put higher trim compressor wheels on their stock turbo) and run up to 26 psi intercooled boost. Now, intercooling makes the air MORE dense and harder to compress, so for blowing headgaskets, it would make that problem worse.... And the little benz engines hold together. One guy ran his for 20,000 miles, then wrecked the car. Decided to rebuild the motor before Really hopping up the power for his replacement car, and when he got it open, realized it didn't even really need a rebuild, with 280,000 miles!!

I've NEVER heard of a blown Headgasket due to overboost in the OM617 Mercedes engines, most overboost leads to skyrocketing EGT's that melt stuff....

Blame those damn POS TTY head bolts as THE culprit for blown head gaskets. Want to run 15 psi all day long? Use ARP head studs for the 6.2/6.5 block. Of course, GM's engineers never envisioned that we'd be hot rodding our engines to 300/600 from the stock 205/440 that was evolved from the 6.2 NA.

We could boost them beyond 15psi (if we could fuel them with a modified DS or DB pump) but the bottom end won't take it. Too bad there isn't an aftermarket FORGED STEEL crankshaft and stronger rods available (HINT WALT!!:D ), but the main caps wouldn't take the extra stress, nor would the block webs, unless you welded them up and drilled them for splayed four bolt mains, then fabbed new bearing caps from forged steel.

I'm suprised that GEP didn't go to four bolt mains, and a steel crank, when they modified and improved the the block casting after taking over from GM. They probably didn't go four bolt to maintain total parts interchangability for their primary customer, the military.

As an aside, deerefanatic, in the early '90's I owned my grandfather's '82 Audi 5000 turbo diesel. I cranked up the adjustment screws on the wastegate and pop-off valves, and turned up the Bosch pump a little, and was pulling 20 psi boost out of that little 2.1L five-banger! Not sure of HP, but I could embarass 3 series Bimmers when passing from 55 to 75 MPH from the gobs of torque it suddenly had (due to gearing, red line of 3400 prm in OD was about 84MPH), and I made a brand new 'Vette look stupid as I blew by his 40 MPH ass at 75 MPH on I-76 up Vail Pass in a cloud of black:D! Best yet, I came back from L.A. to Lincoln on 2 1/2 tanks of fuel, getting a low of 28 MPG on the stretch from St. George, UT to Julesburg CO through the mountains, to a high of 34 MPG from Julesberg to Lincoln at 75 on the cruise control. Boy do I wish I still had that car.
