today i was following my girlfriend in her car! it's a 1996, petrol renault clio and a great little runner! it's just passed its mot with no problems at all but i noticed when she first started it up there was what appeared to be an exsessive ammount of smoke coming out of the exhaust and quite a frequent dripping also out of the exhaust. after about five minutes the exhaust fumes calmed down to allmost nothing and the drip became every so often. was this just because it was the first time it had been started today and the engine was cold or something else that might need looked at. cheers

Smoking when first started, then quits is usually valve seals. Not a big deal as long as it quits in a few minutes. Keep little closer eye on the dipstick.
Tail pipe dripping for a little while after cold start is normal. It's moisture condensing in the exhaust gas. It'll quit when everything warms up. They put little holes in mufflers now so it won't just sit there if you didn't drive far enough to heat everything up.

White smoke I presume? That always indicates the presence of water, while blue or black smoke indicates oil burning. Condensation in the engine and exhaust can make a lot of water to come out when it first starts, so unless it seems to be losing coolant, I wouldn't really worry too much about it since it did calm down and stop after running a bit.
If you are losing coolant, you could have a water leak in the block due to a bad gasket or a crack, but that would be continuous.

It's quite normal for an exhaust to emit steam after a cold start, it's just moisture condensing in the cold exhaust. Same goes for the dripping.
If that's all that's happening and the car isn't losing coolant or any other fluid, there's nothing to worry about.

If it runs on diesel, I would expect a little white smoke to come out the tailpipe when its cold. but if its gas, you could have a too lean of a mixture in your fuel system, or your car has a some worn rings and it has started to burn a little oil, especially after the engine is turned off for 20 minutes or more, and lubrication seeps into the combustion chambers and is burnt with the fuel, hence smoke out the tailpipe. What was dripping? Water? Fuel? Oil?

All that is is condensation thats in the exhaust system that gets forced out as the system warms up, on cold days you'll notice a fine mist that gets blown up the back window a few minutes after the car starts up. Its nothing to worry about, they all do it.

the place is the liberty of selection? Non-human beings who smoke constantly had the alternative to not bypass someplace human beings would be smoking, yet now human beings who smoke haven't any selection in any respect. the government say that this would help inspire human beings to stop. in the event that they choose human beings to stop why not take cigarettes off the shelf, why not ban alcohol additionally, in spite of everything it particularly is undesirable on your well being. of direction they'll do neither of those as they make too lots money from the two. human beings are already asserting that the ban has decrease down lung maximum cancers by using 17%. In 4 months!? don't have self assurance the hype.

If it is cold outside....yes, it is because the car is not warmed up yet...it always gives a white smoke then when the engine is warmed up, then it does usually subside and the drip? yes that's normal for Renaults.

Renault clios need valve stem oil seals changed ,that causes the smoke ,due to oil leaking overnight .The dripping means head gasket needs checking or replacement ,dont delay or the head will warp as it made of alloy will have to be skimmed.

blue smoke from cold starting generally indicates worn valve guides. it's the oil that drains down and lays on the pistons being burnt off. the water is merely condensation from the exhaust gasses.

What colour is the smoke? If its white and you have water dripping its the head gasket gone.Blue worn engine,but clears don't worry just getting on..Black and clears with some drips nothing to worry about.
