Hey all,

 

I'm going to look at a '97 6.5TD/Auto Extended Cab 2WD.

What should I look for with regard to the 6.5TD.

I recall these motors having issues with the lift pump.

Miles are reported low 76,000.

 

Any help would be great!

 

Thanks

These motors were prone to injector pump failures and engine block porosity. They lost coolant through the block into the crankcase.

My uncle is a head mechanic at a huge dealer in ohio. He said that the main thing that he would look into is the Diesel fuel pump... Need to find out if it has been replaced or not cause it has to be done my a certified mechanic for the fuel pump...

I have a 96 K2500 6.5 Diesel with 106,000 miles on it. I have had two injector pumps done in the last 50,000 miles under warranty. I believe GM extended the warranty to 10 years or 110,000 miles. They say high heat will kill the electronic pump mounted driver. You may not have a problem unless you plan on pulling a heavy trailer. In some cases only the pump mounted driver needs to be replaced. As it stands now, I plan on keeping my truck, I like driving it.

Hello to all i am also ;ooking at a 1996 3500 dually 6.5 120000 miles and in great shape the qwner states he has never had it apart and never let him down,i hear all of these guys in here thet say the pumps are bad in them,maybe this guy has a good one 120000 and nothing done, and but the way he is asking 10000 for it its a crew cab dually full load with leather is that a good price for one.

 

Cheers

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
