    Question Colt 2.8TD HEAD

    Hello everyone. Hope I am posting this right. I have read a lot of your threads and taken some advice from you all.

    My Colt 2.8TD blew the head gasket recently. Me not having the money at the time to skim the head had a friend of mine replace the gasket without skimming (I know bad idea).

    The bakkie ran fine for about a week and then began to struggle to start. (I assume it isn't getting enough pressure) This morning it wouldn't start at all and burned out the starter motor (it's old, I have replaced the brushes before and it was long overdue to be replaced).

    The oil light also started glowing when at running temp and only while idling, while moving it went off.

    Here are the things I have done since:

    Replaced glow plugs (didn't need to)
    Replaced battery (was getting old and tired)
    Just burned out starter (will have to replace)
    Replaced oil sensor

    I now have some extra money. Would you guess skimming or even replacing the head will solve the starting issue and maybe even the oil light issue? Looking at this:

    Thoughts on this? Thanks in advance

    Best thing to do is get complete AMC head and replace with new gaskets. Then you can look at if there are other problems still there.
    Then you must plan for pump and injectors to be done asap also.
    Check your cooling system is working properly and no blockages anywhere

    The head has ceramic inserts, which means it cannot just be skimmed.

    Replace with a AMD head, as suggested above.

    Thanks very much will look into doing exactly that, not the first time hearing it can't be skimmed.

    Cooling is fine, replaced radiator recently and did complete flush of cooling sytem. Turning into a mechanic now

    Mine also did not want to start due to air into the system overnight. A booster pump worked for a year or 2 but end last year I took it to Kokkies in Silverton and they overhauled the diesel pump, turbo due to low boost and replaced the cam chain and one glow plug, R17k. So far I am lucky as the head is still original after 20.5 years but I always had an EGT (exhaust temperature gauge) and in the
    rare cases, mostly with bad diesel, where the temperature went too high I new it and gave less throttle. This year I had the radiator cleaned, replaced the thermostat and radiator cap and replaced
    the water pump. Still feel almost new and still enjoying it after all these years.

    There is an old saying about the 2 kinds of Mitsu 2.8TD owner:

    - those that have replaced the cylinder head
    - and those that still have to

    They all break eventually.

    Same is said about the gearbox in my 1Hz Cruiser, after 13 years also still waiting. And both are not only used to go to church:

    Regarding the starting issue, my head just went in my Ranger. After skimming it the car struggled to start, did a compression test and rings were stuffed.

    Sorted out rings and car starts better than ever. Check you compression maybe?

    For the oil light coming on while idling check the oil pump it may be pumping a low pressure when idling it needs to run fast to supply enough oil pressure

    Think what you want. I use all the revs to the red line often, tow a caravan at times with both bakkies and are used to big bikes and a Turbo petrol Jetta (147kw). Just know how to drive a car and
    to make smooth gear changes. Clutches on both are still original and that after many 4x4 trips with a heavy load.
