White smoke from Exhaust

Hi

I recently took my Renault Clio X Reg Auto along to local ATS to fix a rattling exhaust.
They replaced the brackets/clamps/mountings connecting front exhaust pipe to engine.

Days later exhaust rattle returned getting worse. Problems startingcar, started Ok but not smooth and severe knocking noise, which settledafter a couple minutes, when engine ran smoothly, although exhauststill knocking.

Day before I decided to take car back to ATS to sort out exhaustproblems excessive amount of white smoke emitted from exhaust tailpipe. Noticed temperature gauge was reading high, stopped car toinspect coolant level which was low /reservoir empty, so topped it upand drove home.

Tested car today, coolant level ok, excessive white smoke still being emitted once engine warms up.

From researching on internet white smoke seems to indicatecoolant/antifreeze getting into engine system due to head gasketproblem.

Could ATS botched repair have caused problems or I have I been simply unlucky in that head gasket has failed??

Many thanks for help.

    Hi

    Problem solved (at least temporarily), bought some K Seal Permanent coolant leak repair from local car shop for £9.99.

    Put K Seal in radiator overflow, ran car on drive for 20 minutes for it to work, no need for draining coolant/anti-freeze etc, took car for long test run.

    Hey presto, problem solved, no white smoke.

    From internet research this solution might only be temp fix, someone said might last for 6 - 12 months. But for 19 year old car, worth most probably less than it would cost to have gasket professionally replaced, it will do me.

White smoke petrol 1.4 renault clio.not stem


White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.



It is also possible to be a engine problem you should immediate visit a car service.

I have a nissan sentra eccs with automatic transmission 1993 model, the exhaust is releasing a lot of white smoke, is this normal?


sorry but if you have white smoke coming out your exhaust, most likely you blew a head gasket. antifreeze is leaking into your exhaust and out the tailpipe. check your engine oil dipstick and see if the oil is a milky color. your local auto parts store sells a temp fix for it just ask for a head gasket sealer. good luck

1.9 dci no power and bluey grey smoke is coming from the exhaust


There are indeed traces of oil coming out of the exhaust. Blue smoke is burning oil. Grey or white smoke is usually coolant/water going through the engine. This can be caused by leaking head gaskets, valve guides depending on the engine, excessive blow-by, etc. Large amounts of oil are not good; and water is even worse. I would look at getting the head gasket replaced. The loss of power is because neither oil or water likes to burn, and once your engine clears it out, it probably runs ok for the rest of the day. Then I'm guessing the next morning, it comes back. This is an urgent fix, because prolonged leakage can damage the engine block, head, or both.

Hi, what does it mean when huge amounts of white smoke comes out of the exhaust? otherwise drives ok? it is a renault megane 1.5 dci 2004. regards catherine


Symptom: White smoke or water vapor from the exhaust. You notice white smoke coming from the exhaust when you start your car. If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem. Possible causes:
  1. Transmission fluid may be entering the intake manifold through vacuum modulator.
    The Fix: Replace vacuum modulator
  2. Cylinder head gasket(s) may be bad.
    The Fix: Replace cylinder head gasket(s).
  3. Cylinder head(s) may be warped or cracked.
    The Fix: Resurface or replace cylinder heads. (Resurfacing is not a DIY job)
  4. The engine block may be cracked.
    The Fix: Replace engine block.

Renault Clio 02 enging rattling


If it materializes when the engine is under load it could be the fuel you are using. Try a higher grade fuel. Also a common cause of engine rattle is from the exhaust manifold head Shields. These are made of sheet metal and rust out causing what you have described.
