    Could tell us the total cost?
    Even if you are on the right track, you will get run over if you just sit there.

    because the engine becomes weak....common symptoms are:
    • Less pick
    • Less top speed.
    • Noisy engine.
    • Smoke evolving Exhaust due to gap between the walls of the cylinders and Pistons due to which the Engine oil starts to take part in combustion process.
    • engine oil level decreases day by day.

    @ishtiaq & djyawar

    i have mehran 2005... its total mileage is aprox 68000...
    its pick is great... top speed i'll say is good too as it can go above 130km/hr on cng...

    but it gives kinda light blue smelly smoke just for few mins in the morning when i start it.. but it vanishes soon n then total smokeless after that...

    and it is consuming engine oil way to fast...

    i guess the engine needs overhauling.. if so then what what parts of engine might be week n needs overhauling considering the symptoms i hav listed???

    thanxs..
