Me again.Driving the motorway 85 m.p.h oil light comes on.I turn the ignition off and coast along the hard shoulder.Check the oil and it was on minimum,top up and off we go.Stop at my destination,few hours later start engine clouds of smoke which disappeared with in 1 minute.Off we go home,but engine seems lethargic and gutless but above 2 thousand rpm all is well up to 90 mph.Get home check oil shes used another litre.Next day start her,takes about 15 to 20 seconds again lots of smoke which soon clears, again she is not happy under 2 thousand rpm.The van is not burning oil out of the exhaust.I decide to take the turbo pipe off which goes to the intercooler it is dripping in oil.Turbo must be gone? I change it £451.00 pounds all seems great.Check oil it has used another load,where is it going not out of the exhaust.It seems to be pressurising why?The performance is down below 2 thou rpm but still ticks over fine at 800 rpm but oil is going as fast as the diesel.There seems to be a slight tapping noise now and again from the engine could this be a broken piston,rings or top end?

They are prone for blowing holes in the piston when they get a few miles on. This causes loss of power and using oil, when this gets bad it blows the dip stick up and sprays oil onto the turbo, occassionally causing engine fire, so be careful!

The hole will be minute or at the side, if it was an obvious hole it would miss and throw of loads of blue smoke. I could do with more detail as you thread is not that informative for me to get much from it.

Do any of the cylindes look damp or oily in any way? Is it a 5 or 4 cylinder, 5 cyl usually blow no 4 piston, 2000 onwards ie a cdi engine. Does around the dip stick look oily?

Dear Dava,the engine is a 4 cylinder.The bores look fine,if anything the back one looks a little bit oily but not excessive.The valves look a bit coked up but look as if they are sealing.The top breather pipe is the one which is smoking alot and the dip stick hole,but the oil looks as if it is being pumped out of the turbo(brand new remember)through the intercooler and up the hose which holds the air pressure sensor etc.why is it doing this? could we have fitted a faulty new turbo

I think it's nice when some one comes on here to tells us the out come aswell as saying thank you. Thats all most people ask on here, it took me years and a lot of money to get the knowledge that is available for free on here, glad you got a result, allbeit an expensive one. Before you dive in buying new parts, price an engine up, they are expensive but we find some times it's as cheap to buy a new engine than to repair them, the engine comes complete with clutch turbo the lot, plop straight in.

Friend of mine fitted a new turbo to a leyland engine and failed to prime with oil before starting, blew the new turbo. Revved the Ba??s off soon as he had started the engine.
