    Default Diesel Pajero cold starting issue

    Hi all
    Recently, I purchased 1992 model Pajero diesel 2.5TD. Im facing the problem of cold start. In the morning, it refuses to start even after 10 heaters. After 12 o clock noon, it starts after 2nd or 3rd try. And after starting once, then without any heater, it is half self start. Also gives smoke at start.
    It is driven more than 300k kms. I want to know from experts whether it is due to glow plugs, timing, valve seals, or nozzles of pump.
    I know the problem will be resolved after this cold weather but want to dig out the reason. Also suggest any other solution if needed.
    Shall be grateful for this help.
    Regards

    You got a new high pressure head and a new delivery valve under Rs 6000/-??????????????

    how? the high pressure head alone costs nearly 100 USD.

    That leak is the pump top hat leaking. Requires New sealing O ring replaced, which also translates to pump top disassembly. While at it make sure the LDA works. btw this leak can cause your misfiring and also hard start as the pump loses prime and air is sucked in causing foam in the diesel fuel (foam does not make pressure - liquid does)

    Clean the pump and check for the leak.

    btw what area are you trying to grease with waterproof grease?

    Thanx for the help. Can this leakage also contribute to high fuel consumption? BTW is this o ring inside pump assembly? What is LDA?

    if you find salim diesel pump wala good, then you will be literally amazed at the work that the old DPS did. The problem I found will literally all small diesel pump shops in Karachi was they did not know the importance of the LDA, break pressure, internal pump pressure, hydraulic advance, speed limiter etc. For them they just make a pump move and hand it over.

    Anyone can make a pump work 80%, it takes three times the skill and proper literature to get it 100%.

    whats wrong with using Delo Gold if you want mineral oil.

    If you want a really good flowing oil for winter - you need mobil1 diesel 5w40 or similar. Havoline 5W40 also is good.
