    Default KB72 D-Teq 250 MOTOR (overhaul / replace)

    Good Day all.
    I had a shocking experience over the weekend..
    Sump was leaking oil... and these models do not have a sump gasket.. it has to be made up with gasket sealer.
    Anyway.. The mechanic drained oil... removed sump... cleaned it out, and put new sealer / oil / filter... BUT
    Got pieces of metal in the oil pan...
    So now...my question..
    The mechanic has submitted for a quote from engineers to overhaul (worst case scenario) or rings and bearings only..
    I am awaiting the quote..as this needs to be sent of to the dealership whom I bought the vehicle from..
    So far they sound very keen to pay for the above... however.. nothing confirmed yet..

    My question is though... overhaul the motor or replace the motor (personally I feel better with it being overhauled)

    Awaiting responses..

    Whats the mileage on your engine?

    If it comes to it, I think overhauling will probable be a safer bet (if done properly and through a RMi accredited workshop - for peace of mind and extra guarantee), you have no idea of service history of a secondhand motor and if it's not well taken care of, you will be back in the same boat.

    I hope you sit down when you receive the quote. I too was in a similar position with my KB300. Got quotes around the R90k mark to rebuild my engine and for a REMTEC rebuilt engine R90k upwards.

    Good luck with your choice.

    How many Km on the engine? How many Km since the last service? What metal did he find in the sump? Was it white metal, steel shavings, brass? It is normal to find a bit of fine sludge in some of the hollows in the sump. Is there any steel shavings caught in the sump pickup? How was the engine serviced before?
    Oil drained with a pipe down through the dipstick tube? Oil drained from the sump plug? That steel could have been laying in the sump for along time as all the oil is not drained with a service and the oil pan/ sump is normally never cleaned. Is there something wrong with the engine performance? Does it have a knock or funny sound? Does it consume oil? Is there excessive blow by?
    Too many questions unanswered to warrant a rebuild.

    How many people/workshops that you know of are draining oil through the dipstick hole, when there is a drainplug available?

    Agree with Pieter is the mechanic not jumping to conclusions. Is there anything wrong with your engine in the 1st place? Rather start by having a couple of tests done

    I have seen exactly this done, to my 250 D Teq Isuzu, at the Isuzu dealership in Umhlanga. At the time I was gobsmacked to say the least. Was quite a few years ago, do not know if this is still done.

    How long ago did you buy the vehicle from the dealership? Consumer Protection Act covers six months if I am not mistaken, if within the six months, take it back, claim money back?

    BMW, Merc and many more. They don't use the drainplugs anymore. I bought my Suz on 190k. The first time i serviced it myself, it still had the yellow paint marking on it. The drainplug had never been removed

    Hi,

    *I managed to get all service details on the vehicle up until 165415 km's, however that was last one done (with notes added Fan belts / crank shaft seal to be replaced) in May 2018, car now has 173000 km's
    *Performance is still very good, car drives very nice.
    *Slight tappet noise when accelerating - Well... sounds similar to a petrol engine when tappets make noise...
    *Using a lot of water though but not overheating... temperature gauge stays just below half...
    *Oil leaks (not only at oil pan gasket / seal)

    Diesel engines are a bit louder than petrol engines.
    With the engine running, use a large screwdriver like a stethoscope in different areas to determine where the noise is coming from.
    The third pic looks like a piece of a timing gear, which could cause the knocking sound. It would be very easily identifyable. This will certainly have to be replaced as it will excellerate wear on the gears and lead to engine failure. Remove timing cover and check.
    It could also be from somewhere else on the engine.
    Check for water leaks behind and under the waterpump and all the pipe joins. Also check if the radiator cap is in good order.

    Hi, Thanks for the feedback it is greatly appreciated.

    Please correct me if I'm wrong...As the name clearly states "Nuweling" and this is my first ever Diesel / Isuzu..
    How would timing gear particals end up in the oil pan? All the timing gears / belts / chains are in front of motor behind cam cover, and there isn't supposed to be any oil in that part of the motor unless the partical somehow entered into the motor through the cam seal / gap.., please correct me if I'm wrong...

    The motor is being stripped anyway to check overall....

    Once again.. thanks for all the responses / feedback.

    Oh wait a minute... I had a look now at the diagram's of the motor... yes, the timing chain sits behind the fan belts, inside the engine.. so yest.. it is lubricated with the engine oil.. ..
    *Radiator
    *Fan belts with pulleys
    *Cam cover
    *Cam gear with chain..

    Okay...
    So it seems the Dealership want's to rather send the vehicle to Williams Hunt in Pretoria to have the repairs / work done...
    Fine by me...Actually better maybe...

    HI Nuweling I'm very sorry to hear the bad news on the motor... Hope you can be back on the road with your trokkie soon!

    So tell us a bit about your story, it sounds like you bought your 2012 KB72 quite recently, was all fine when you bought it?

    Where or who did you buy from?

    This is a horrible start to your first diesel vehicle. Hopefully from here on it only gets better with many safe miles and adventures in your Suz!

    Hi yes you should still have a warranty of 6months on it if was bought recently that also could be old debree from previous damage possibly seen that before if car is runing fine then why rebuild just check bearings sounds like a possible head gasket or water leak instead Run a 15w-40 oil if u can delo 400 is perfect for these motors
