    Have a look, you will find it.

    I changed fuel tank rubber pipes when i got new fuel tank. I did not change metal fuel pipes.

    I believe fuel tank rubber pipes can be changed easily by removing rear seat.

    @axe.effect The pipes are visible clearly from under the car but they go through the floor from 2 holes. I removed rear seat but couldn't find any way to access those pipes.....so i think fuel tank has to be removed to change them.

    Oh, sorry for misguiding. But now since you have removed the rear seats, so do this.

    Get those pipes changed by mechanic then. Fuel tank removal and fitting back is not easy DIY at home.

    I had a look again under the car and there are two pipes going from fuel inlet(fuel cap), one is large and other is small. This is why every time i go for a fill up fuel spills out and then has to be slowly filled.

    The smaller pipe goes to the top and the large one is somewhere in the middle. Both would have to removed along with 3 or 4 bolts.

    Any idea about the size of pipe used on the tank to the metal pipe? Same as used in engine bay?

    Yes, fix that quickly, it can be dangerous too. The size is same 1/4 inch, to my knowledge. Let's confirm it from Mr. Smijaz.
    @smijaz
    I was told by many people that fuel pipes size is 1/4 inch (6mm). Do you agree?. I have fitted those pipes, no leak, but i find them a little big (loose).

    Compression test. Do it first and share results of both dry and wet results, before reaching any conclusion about what is wrong.

    Yes its possible. have done it myself in my khyber and cultus.

    Its important to just do it one piston at a time and keep the piston at TDC before you remove the caters and spring.

    To lock the position of piston at tdc , use a screwdriver to fix the flywheel through a whole under the gear box. its specially there to lock the crankshaft while opening the timing belt crank pulley. your mechanic should know this.

    Cylinder head.
    Headgasket.
    Engine block.

    I always thought cylinder head and engine block were same thing, but they are not.

    NOK it will cost you like 50 per piece (it will be plastic wrapped pack of six)
    SGP (OEM) it will cost you around 250 - 300 per piece (individual plastic pack)

    NOK works but if engine heats up even once they are gone. so do the math and decide

    Could not convince my mechanic. He said it is very khuwari job. He was not getting my idea i think. So did nothing much today except timing belt change, alternator belt change, tappet adjustment, break pads change, and break fluid change.

    Breaks are quite loose now, have to press them like 75% to stop the car. Mechanic said that as break pads are new, it will take time to be normal. What do u say?

    He also said that maybe rear breaks shoe need to be changed also.

    Break fluid was changed and air was removed from all four wheels by pumping pedal method.

    And if u may please explain procedure in detail so that i can explain it to my mechanic for changing valves without opening head.

    Thanks!

    brake shouldn't be loose, either there is still air in the system or worst case, your master cylinder went bad. maybe you pumped too far

    Tomorrow is brake bleeding day. @smijaz @Xulfiqar

    Question: brake bleeding is done with engine on or off?

    Correct me, if there is something else left for brake bleeding.
