the main sign of weak engine is that is exaust black toxic smoke plus also creats problem during starting plus also weaken spark plugs.
smoke..
Too much vibration
Rapid reduction of mobil oil
over heating..
Giving smoke..
mobil oil in sparkplugs
usually the first sign of a week engine is the pipe goin from tappet cover to air flirter blows oil from it which makes the carbarator cover and air flirt messed up....later you can see white smoke from your silencer ...which will lead to reduction of oil level in a car...which will cause the car to heat up......which will further lead to leakage from differenent places....
the first sign mention by Tunparty can b seen in my car ..but its not throwing oil ..its throwing smoke..and on the other hand ..silencer is throwing water drops .. what does it shows?
sorry my mistake ...it blows smoke...later wen the rings of piston wear out it will start blowing oil in da carb
well is your car cng?
One more question please,
I got my Engine oil changed 16 days back and today when i checked it ,the engine oil rod was showing me a little of 4cm of oil less from the full which i had 16 days back...is it normal? does this oil also get finished someday like petrol? how much days it takes to finish if not refilled or changed ?
nah this isnt normal you got a weak engine....try checkin your engine oil again...where surface is not tilted or uneven which will make your engine oil to stack up at one side!
and dont check your engine oil ryte after u came back from a drive give it like 30 mins to settle and cool down

ya my car is on cng .. but why does it give smoke under aircleaner although car's silencer is throwing water drops?
@tunparty i checked my engine oil rite after a drive of 2 hours... maybe thats why :S ? but how it could be weak as its only 3 to 3 centimeters not inches...isnt it normal for a refill which was done 16 17 days back :S ?
@Zilla..
My car used to throw out oil in the bonet and later on it was found that the guage for checking the gear ail was loose... Do check it...
Regarding engine oil do check out that the screw for taking out the engine oil present below the oil chamber is properly closed and not leaking... and that the dip rod for checking the engine oil is properly inserted into the chamber...
@ trojan
water drops from exhaust while warming it up in morning shows that engine is in good condition.
correct me if i'm wrong.
this is wat I say zia..but my car is also giving smoke plus smoke from the pipe attached to air cleaner.
my car also throws water and no smoke...but the problem is that i am confused that where that 3 or 4 centimeters of engine oil has gone through last 16 days.....does the oil ever vanished or it decrease ?
@trojan & others
i have the same problems in my mehran w/o CNG.
Smoke from pipe(Only when i start the car in morning) but Saath main water drops bhi
Oil Vanished 2 or 4 cm in around 16 days.
When ever ill drive my car around 1 hour the water vanished from uperside of the rediator.
