I have just got home after a very frightening (for a "know very little about cars" person) journey.
About a week or so ago I noticed an unusual noise from the engine on my 147 JTD 16V M-Jet (53 plate). Best way I can describe it is like gravel / fine stuff in a cement mixer type noise when revving above 1500 - 2000 ish. It is not the engine which still appears to run fine. Best I could locate is where the air intake pipe joins the engine.
Today, I started the car cold and when it was about halfway warm, noticed a lot of smoke from the exhaust. As it has been very cold, I continued, until it started billowing out from under the bonnet and into the car through the vents!
I pulled over and popped the bonnet. The smoke appeared to be coming from the back of the engine, near to where the dipstick is located. When I took the dipstick out, there was a release of pressure (like when you open a bottle of pop)?
Started up again and got it home, but the engine felt "lumpy" and stuttered when driving. Popped the bonnet at home and gave a few revs and again got smoke in the engine bay, this time appearing to come from front right side of the engine. Not sure exactly where as I was in the car when revving and it stopped when I wasn't!
I have recently replaced air filter and MAF sensor which cured a lack of power issue, but I'm not sure what this can be and I don't want to keep starting and driving incase I'm going to cause more problems!
Engine had a bit of a rebuild 2 years ago aftert a snapped cam belt.:cry:
Any help or where to start would be really welcome!

Just looked black and oily, nothing too unusual I don't think:

When I drove the car home, it was far less smokey, but still a fair bit from the back.

I have tried to upload 2 videos, 1 of oil filler and 1 of smoking in engine bay, but it didn't work as the file type is wrong. Any idea what video files this will accept? I'll try to convert it!

That's a good plan!
Doesn't seem to be much smoke now, but when driving before, I literally had my own smoke screen! Smelled like burning oil, you know the smell when the engine gets too hot or if you've spilled a bit on the exhaust... but I haven't and the engine wasn't too hot.
As I said, it was coming from exhaust, from under bonnet and even through vents, but now, although smokey, no where near as bad.
A friend suggested that the turbo may have frozen up and then any dirt etc may have freed off and be burning? Don't know if this is plausible or not?
I'll try the you tube thing, but don't hold your breath!! :lol:

Yes, checked coolant, pretty blue colour and no sign of oil:thumbs:
It was slightly below the min mark, so have just topped up.
Just started engine for video purpose and there is now very little smoke. Still get a bit when revving above 3000 which rises from between engine and battery. Not enough to video though. Wondered if maybe engine being warm made a difference as it had cooled, so I've left it running and will keep an eye on it.

my feeling is turbo.........buning oil......smoke through exhaust.......... :-(

take bottom turbo hose off if u can and see if the impellor is still intact, a turbo on a car cannot freeze up, as water isnt involved

i would say turbo as well, given the noise it sounds like the bearings went in the turbo, which i suppose in theory could allow some pressure back through the oil lines and add a small amount of pressure to the sump, hence release of pressure when taking dip stick out.

as above take hose off and check for play in turbine shaft, would suspect it to rattle like hell. would also burn oil and create smoke if its gone.

check oil level and be sure to maintain good levels.

Sounds like turbo bearings to me too - seals fail allowing engine oil to be sucked into the motor and burned. Get it checked ASAP, before more damage gets done to the turbo - a rebuild by a specialist is a quarter the price of a new one. There is also a possibility of runaway. That's when seals leak so much that oil is drawn into the engine enough to make it rev itself to death even when the throttle is closed and fuel is cut off. The only way to stop it is to stall the car on the brakes, or wait until all the engine oil has been burned and the motor destroys itself. It's rare, but it does happen. You'll find a few scary videos on YouTube if you search for "diesel runaway".

Mr. AA has confirmed that Turbo is no more :cry: So next question is where to get a replacement. New C £800 :wow: Recon £500 and second hand either £350 with 1 year warrant or £282 with 60 days.
The £350 option looks best unless anyone knows of a better / cheaper deal. Of course, on a 53 plate, the scrap yard is tempting!! :cheese:

£500 for recon is taking the ****** an hours work as tops plus bits

advice here from a dude who builds turbos for a living........ be very very selective when sourcing a recon as it will only be as good as the person who works on it, and.......are they using genuine parts.......the levels parts are machined to isnt often the same

turbos do not wear out if the oil as been looked after so buying a second hand one that is from a well serviced engine would be my choice as, if its original then it should be like new, the bearing in a turbo is actualy the OIL ! dont be thinkng there are ball bearing type bearings in them, as nothing can spin fast enough so the shaft floats on a film of oil.

if looking for second hand try also looking at fiat vans with same engine cold be a cheaper deal ..........:)
