Self Tunning - Khyber G-10 (Plugs, valve clearance, spark gap etc)

[metalhead]

Hi All,
Need to ask a problem I am facing with my Khyber 95. When I start the car in the morning it vibrates alot. I got it checked with a mechanic and he is saying and it is vibrating due to cold engine. I want to get rid of this vibration in the morning, the car give a smooth ride later on.
Problem 2: few days back when I checked my car, i found oil in under the air filter. What could be the reason for this ? Not only oil it was a surf(form) of oil.
Problem 3: Some time, the cars gives missing in 2nd and 3rd gear. Any idea... All suggestions are much appreciated.

If the vibration is due to low rpm, then use choke to increase the rpm until its stable enough

Check your PCV valve. May be its stuck open. Could be a valve guide/seal leak.

Could be bad tuning, bad plug wires...

What could be the problem...
My cars starter solenoid switch disengages while cranking. The starter spins but the pinion disengages. I have to wait till the rotor stops and then it starts normal. This only happens when i switch off a warm engine and then start within a minute or two. Never happened while cold starting.

Please suggest...

Weak solenoid winding ,resistance get high when hot not able to make enough magnet to hold the switch.

My guess is that in your car radiator fan is in direct mode and electrical load idle up mechanism is not present or maladjusted.

Your engine is running cold most of the time so the oil is retaining crankcase moisture instead of steaming it out, engine is running rich and blow by will be excessive. So Check PCV also.

Check ground connection, plug wires and ignition timing. (For missing problem)

Connect thermo switch with radiator fan and if possible install thermostat valve. Dont forget to use coolant otherwise just forget whatever i have said. (H)

Try installing a relay for the solenoid.

[Xulfiqar]

the solenoid hold coil is bad or is losing ground connection, check the field windings wire connections for bad ground connection

usually the solenoid goes bad after a long service life, replace it.

Thanks for the replies

Ground connections will be checked and cleaned first. Service will be second and if the problem persists then will change the solenoid.

Ijaz bhai, sorry i had already many relays installed; ignition, headlamps, blower fan. I dont want one more.

xulfiqua bhai i was wondering that can carb engine be converted to efi???? if yes then plz explain a little

Today when I opened air cleaner element of my Khyber to change the air filter, I saw white residue kind of paste near the outlet of Positive Crankcase Ventilation Valve. When I opened the oil cap, same white paste was there too. I am using Petromin Ultra 7 oil (20W-50), the dipstick is showing normal oil level i.e near the maximum mark.
I have taken the pictures.

[Xulfiqar]

that is accumulated moisture mixing with engine oil vapor. What is your engine operating temperature?

[speedster_101]

Engine temperature is around 30-35% of the gauge. The fan is automatic and thermostat valve is installed.

The car is also reducing water. The radiator and side bottle is empty every morning, I have to fill it daily. But the radiator guy told me that the radiator cap is faulty. I have changed the radiator cap, lets see it reduces water now or not.

check head gaskit , its leak and mixing radiator water with engine oil , one it happens on my fx

this idea came in my mind some time before when i see my mamu's baleno giving tons of trouble because of efi stuff,,,,,,,,,,,,,,but here i was thinking to change its air intake along with all the efi stuff with the manul one like we see in margalla ,,,,,,,,,,,,,,,you thinking opposite of that

Most probably, its the head gasket, if the engine temperature is not too cold. Your coolant is mixing in the engine oil...

[Xulfiqar]

you have a head gasket oil/coolant leak, fix that.

Can it be malfunctioning PCV ??

If the engine is leaking compression through head gasket and its pushing water from the cylinder jacket in to the oil passage then you will also have extra pressure in your coolant lines.

You can confirm this by removing the radiator cap (while cold), fill up the radiator and start the engine if coolant is jumping out of the radiator mouth or you can see continuous stream of bubbles , the head gasket is gone.

But my guess is your PCV is not evacuating crankcase vapors .

Ijaz bhai, that white creamy paste on oil cap only occurs when you have coolant mixing in oil. If oil mixes in coolant, you can also see greasy material on your radiator cap as well. So as xulfiqar diagnosed, its definitely a bad gasket.

And by the looks of it PCV can be checked but as you can recall as well, there is usually minor oil deposit on the air cleaner housing where tappet cover/PCV hose connects. The white residue seen now is because that oil is now carrying moisture in it.

Yes, when I open the radiator cap and press the accelerator, water starts pouring out of the radiator neck.
If PCV Valve is bad and it is not evacuating crankcase vapors then why the same white paste is present in air cleaner in front of PCV valve outlet?
