  • suspect holed piston - what should i replace (pistons, rings- anything else??)

    I have a 2010 3l diesel with a suspect holed piston - description of symptom below
    I bought the car as is and got it cheap so this is not a whinge thread but more a what should I replace thread :-)

    car starts with a hick up and runs rough, after starting it idles up to about 1100 and the engine is shaking a lot. Pull the oil filler cap and excess blow by - comes in regular big shots, not a heap of smoke but a bit, if I pull the dipstick I get the same woosh woosh woosh and smoke
    I connected a "Launch" scan gauge and it came up with 2 errors (no code just ad error) which both said injectors.

    Car has done 190ks, So assuming there is no damage to the block apart from replacing pistons and rings and injectors (timing belt too I guess) is there anything else that should be replaced? - not looking to take to it with an open cheque book but whilst it is apart may as well address anything obvious

    cheers

    bit hard to diagnose without a teardown , but i would start with a compression test ( even a finger over the glow plug hole will suffice ) then once the head comes off check to make sure the bore hasnt worn oval or has gouges from the cracked piston .

      it just gets better - moving it onto a tilt tray last night to go to mechanic the engine seized/locked up.........

      Should be easier to diagnose now! (gotta try and look at the funny side of this right!!)

        possibly the piston has cracked in two and has now siezed in the bore. Ive also seen the pistons fail at the gudgeon pins in one motor - that motor had great compression but sounded like a bag of hammers

          Should have gone the petrol This is exactly why I got my petty a couple of litres per 100km is much cheaper than a full rebuild the D4D is the engine that will ruin Toyotas reputation with diesel engines it should be called the common fail.

              And this adds what to the discussion?

                I hope you got it really cheap then just buy a wrecked hilux or the engine and use that.

                  Could be an opportunity to repower... with something different.

                      I was thinking along those lines.

                        Cummins 4BT is a BIG engine. 3.9L, Weight: 782 lbs w/ oil (355kg), 105 hp @ 2,300 rpm, 265 lb-ft @ 1,600 rpm

                        What is the weight of the Prado's KD engine?

                        Cummins Crate engine. 2.8L turbo.

                        https://cumminsengines.com/repower.aspx

                        Torque: 267 lb-ft @1500-3000 RPM
                        Horsepower: 161 hp @ 3600
                        Dimensions: 28.3 in (H) x 25 in (W) x 25.1 in (D)
                        Engine Weight: 503 lbs (230kg)

                        Would it be possible to have emissions approval for the Cummins?

                          That 2.8 Cummins is down on power (360Nm) when compared to CRD's available today.
                          Holden Colorado 2.8 > 470Nm
                          150 Prado 2.8 > 450Nm
                          Fix up your D4D.

                            Oh, well if you're chasing the torque of a 3.0L Diesel engine, the D4D aint even in the race...

                            Several other options there... Don't seem to have been having as many engine issues as the D4D, but not easy to find the info. Even Toyota doesn't reveal the failure rates.

                              Looks nice, can't imagine that it would be a simple retrofit. Also high torque and power never come for free, fare bit of complexity.
