SCENIC DCI BLUE SMOKE?

[anthony25]

hi all i posted this thread on here a few weeks back...my friend has a 2004 megane scenic 1.5 dci...the cars always run fine up untill a few weeks back,the car seems to throw blue smoke out mostly through 1st,2nd,3rd gear up too until you get upto speed and it seems to stop,it picks up speed ok as it should,ive done an engine flush today,also give it fresh oil and filter,run sum injector cleaner through it all to no avail it seems,the smoke has a sort of burning smell in it,i can hear a whistling sound from under the bonnet when accelerating which my friend says hes never noticed before,ive never owned one so wouldnt know if thats normal etc...any pointers here is always appreciated thanks??

[anthony25]

just to add...there is no smoking at all when the cars idling,but rev the car and it will smoke.

The whistling is probably the turbo which is usually audible when the windows are open, so if it's on its way out the whistle may become more prominent. The rally cars I've seen limping back off the stage with a blown turbo smoke like hell.

The head has to be removed to do it right Anthony. do you find it smoking blue when the car has been stood overnight & only first thing in the morning?

[anthony25]

hi twr no..it smokes all the time from cold hot etc...get the car upto speed say do 60mph on the d road and there is no smoke at all,seems to smoke when revving at idle,and when building upto speed etc...i noticed yesterday when looking directly under the bonnet..the black plastic pipe which comes from the turbo on the right hand side seems to have alot of oil from where it connects to the turbo itself,it looks as if its leaking oil ???

[TWR]

Internal oil seal within the turbo, IF that is the case, it's been a cheap Fix in comparison to the Valve stem seals Anthony.

[anthony25]

i take it the turbo has to be removed to fit new seal etc?

Just been having a look at the pros & cons regards this Anthony, when your friend car has had the right diagnostic on this, do not jump for the "NEW UNIT" you can either go for a recon with 12 months warranty, one from a scrap yard or a Megane breakers, or 247 car parts on Google, the turbo is not a big job to remove, it can be done in a matter of 2>>3hrs, I would FULLY CHECK the pipe work to the turbo first, check that the oil is not getting lost, it seems that the oil is dropping into the inlet, but I may be corrected on that, but what ever, running with a defective Turbo can cause further problems so I suggest you get it checked ASAP.

[anthony25]

can the replacement seals be purchased etc as had a look on ebay cant seem to find any,maybe a main dealer part etc?...thanks

[anthony25]

I would search around your area first Anthony, what part of the UK? do not rush into buying a replacement without getting the right Dio on the problem, do not go to K.F. otherwise you will end up having to bye a new engine, if you are not well up go to a local small family owned garage but do not take their first answer as final.
