Ford Mondeo Turbo Estate W reg white smoke, lots of it, from exhaust . Head gasket not the problem, does not seem to be
oil being burnt. Could it be a problem with the fuel injectors ?
Or is it something else.
Have entered Escort as the Model because Mondeo isnot a
choice. BUT IT IS A MONDEO
Hi there, The most common concensus with white smoke is coolant leaking into some where in the combustion chamber as in head gasket, however you have said its not. turbos unless there is massive internal damage usually blow out black/grey sooty smoke. Is there bearing noise in the turbo at all? or Loss of boost? If so it could be early indication of the turbo failing. I would reccomend goign to a mechanic and having a leak down test perfomormed. Sometimes called a compression test. Or you could buy a decent compression tester and check it yourself. IT coudl also mean tha tna oil seal is blown or leaking Check your coolant resivour to see if there is any oil in there and check you oil dipstick to see if it is milky or off colour. Generally if there is either of these two it means that there is some \sort of leak between the two systems Oil and coolant. Anotehr common problem with these engines is a crack or warped head itself. However if your sure its not either of the above it could possibly be water getting into the combustion chamber via the injectors as in dirty fuel, however you would notice knocking and predetonation/ pinging surely. and generally the car woudl be running really rough. Make sure you keep a good eye on the coolant level as if it runs out it will surely kill your turbo friend. Hope this helps you out there, Cheers STeve

White smoke is an indication of water in the exhaust. This can be from condensation in the muffler, but that type of smoke usually dissipates after a minute or two of running. Constant, thick white smoke is usually a sign of water leakage into the combustion chamber(s), either via a blown head gasket, cracked head, or cracked block.
Regarding 2001 audi a6 quattro 2.7t....i was driving to work the car was fine then white smoke starting coming from under the hood and tail pipe. i stopped veilce and alot of oil was dripping from front of car. I towed it home and i looked under the hood and there was oil from valve cover gasket. i let the car sit for a few days, had it running again for a good hour and no white smoke was coming out. I removed the valve cover and gaskets are all bad. i want to know can the valve cover gasket leak cause the white smoke to come from exhaust pipe?
This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.
Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.
What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.
The white smoke you are seeing is steam. From your description, sounds like you have coolent seeping into the combustion chamber, mixing with your fuel/air, and exiting out through your exhaust as steam. 1, blown head gasket. 2. cracked head or block, 3, warped head due to overheating. Most common is #1.
What happening is you have a bad head gasket or its starting to go bad. As long a little oil is getting in to cylinders causing that smoke once it warms up that gasket is expanding thus the smoke stops. I would keep an eye on oil levels if it gets milky replace gasket asap. Could also be intake gasket but highly doubt it this sounds like a worn head gasket.
It's very simply to find out if the turbocharger is causing blue smoke from the exhaust vs a blown head gasket. So, remove the turbocharger's compressor inlet centre hose (from the aluminium side of the turbo). Then see if there's in plenty of oil coming out from the hose and from the turbo. I'm 100% convinced that the turbocharger is damaged in your case. You can remove also the exhaust pipe out from the turbocharger, and see if there's a lot of oil coming out. Repair or replace bad turbocharger with a new one (or with a second hand in good condition one). Good Luck!
One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.
blue smoke out of 1.8 turbo its allways bad oil seal inside turbo.need new turbo or rebuild OEM. with 24 years experience working with vw never seen single headhasket go bad on 1.8 turbo engines.blue smoke its 100% turbo every time
White smoke from exhaust = water into the cylinders, when this happens it usually means head gasket gone or starting to go. Check the water level, and take the car to the garage for a check up , if it is the head gasket, as I think, you risk to blow the engine at any time.
