Hi, I've got a 51 reg escort van with a 1.8 non turbo endura de engine, it was chucking out large amounts of grey smoke when under load and using lots of diesel, but since running it down on fuel and refilling it is now chucking out lots of black smoke on acceleration and under load and seems to have no power, any ideas welcome, Cheers

Find the fuel injector, then trace the fuel rail backwards to the connector, might be a saftey clip on top of the chrome plated connector....it's round and needs a special tool to open the spring inside the connector. The link below is for a 3.0L Taurus engine, same connector though.

General rules of thumb:
Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings
High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings
Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides.
VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.
I have a 1998 ZX2 with 193,000 original miles. For four years it has had a turbo on it and I run 13's in the 1/4 mile at the local drag strip. So far, the engine is holding up just fine. Now, the transmission is a different story. But, if you aren't beating the car up every week at the drag strip or trying to destroy a set tires with a smokey burn-out, you won't have to worry about the transmission.

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
Grey-ish smoke sounds like rich mixture,not oil burning.Grey-to black is usually excess fuel.Whitish smoke is coolant being burned-bad news! If rich mixture,check for air intake leaks (air intake hoses/manifiold gasket),MAF,fuel pressure regulator.
