    It is just touching the upper hole of dipstick. So its ok.
    In order to check PCV valve, I have to take it out first?

    Thanks for showing the location of PCV valve but this isn't Khyber's engine. Is PCV valve located at the same place in G10?

    Ok found the location of PCV valve, thanks for the pic above.
    I have checked my Khyber's PCV valve by blowing the air into the valve, the air was going in. Then when I sucked air from PCV valve, the air was not coming out.
    Then I started the car and placed my finger on the pipe connected to PCV valve, there was a feeling of suction.

    Is PCV valve working correctly?

    ^^The direction of air through PCV should be otherwise. It allows pressure generated in the crankcase to be released, but does not allow any air to enter.

    You and speedster are saying the same thing. Because the PCV in khyber is on intake manifold so speedster being on crankcase side is able to push air in the intake manifold and not able to get it out.

    His PCV is good.

    Now this is getting confusing.
    I think one end of PCV valve is mounted in engine so we are left with only one end through which we can blow or suck air.
    But I googled it and found on some foreign website that you should experience suction when the car's engine is start and I experienced that suction.

    No confusion, the PCV in your khyber is working. Now Check the condition of the spark tip side of all spark plugs, if possible post their pics.

    I installed the sparking plugs 2 months ago. Right now I don't have the tool to take out plugs. Tomorrow I will ask mechanic to do that.

    Today I went to mechanic to see the condition of my Car's sparking plugs.
    According to the mechanic, they are in very good condition. No oil on plugs at all.

    Default Head Gasket

    I want to know about head gasket.In market there are single and double type gaskets available.
    what's the difference in them?
    and when i overhauled my car's engine then the mechanic put two single type gaskets instead of one gasket and when i asked why,he told that your cylinder head is faced so two gaskets are needed.
    Is this a standard practice?

    This is not a standard practice but a malpractice of desi mechanics.

    when the engine head surface becomes uneven due to one of many reasons like over heating or uneven/over torquing by the mechanic. the head needs to be faced very slightly in order level up the surface for maximum even contact. It is to be noted that there is certain limit to which the head can be faced after that it is to be replaced.

    The counter surface to the head is the engine block, if the engine head needs surfacing then there are 90% chances that the block also needs it.

    if not properly done or over done by the lathe worker the over heating will not go away and also the timing belt will stay loose with standard tensioner.

    Mechanic do this when they only face the head and not the block. they know that the standard gasket will not cover the difference between surface contacts and timing belt issue. So they use the double or two standard ones to fix this.

    So, bro
    Get the engine head and block faced from a reputed professional as he will be able tell you the real story if the head / block can be faced further. then get a the genuine SGP head gasket. Be sure to get the mechanic who know the proper torquing sequence and has a torque wrench in order to apply proper and even torque to all 8 bolts. You will then love the results

    Yes all three were like this.
    When I told the mechanic that there is some oil in air cleaner but no oil on sparking plugs, he said that its engine blow and this is the 1st symptom of engine getting weak. The next symptom would be oil in sparking plugs and dark smoke from silencer.
    What do you say regarding this.

    Also tell me what would be the price of good kabli steering for Khyber?
    My existing one gives kharak kharak sound on bumpy roads. I got it repaired two times.

    That is what I thought when I asked about the plugs. Technically each piston has two types of rings namely 2 compression and one set of oil ring. In your case compression rings are not sealing the combustion/expansion chamber properly but oil rings are maintaining the oil seal. So oil is not getting in but the pressure is getting out.

    This condition can last for quite a while until the deposits from the chamber will get better of the oil rings too.


    No idea of kabli steering price, sorry
