Sounds like it is running on its engine oil. I could be wrong, but I think that engine has a problem with the intake manifold that can crack and allow oil to work its way into the cylinders.

More research on what you have reported, will lead you on to turbo charger "bearing" wear problems caused, generally, by an insufficient flow of oil to them. In the case of the above engine, by not using the right type of oil and leaving it in for too long until it becomes too thick. You need to use synthetic 5w/40 (diesel use) oil in this engine and change it <9k mls/1 year period. If you have done otherwise then beware! But if you look after the 2.2Dci as I have described, it will run efficiently for a big mileage. As unthrottled points out, the plastic inlet manifold can also warp causing intake and running problems but consider the TC bearing wear problem first. BTW, do not be tempted to run the engine until you have examined things carefully, as this could wreck it!

yep most of the research I have done does report the thr Turbo charger. I have also read that there is a mechanical actuator that can stick. Is that a possibility? I havn't run the engine since the last episode. Thanks

The "wastegate" that I believe you are referring to, limits boost pressure by diverting the exhaust gas away from the turbine wheel and is "informed" by a pressure sensitive actuator. There is a metal pipe with a rubber L shaped connector at the rear of the TC and you need to ensure that the rubber connector is intact. But from what you have described, I don't believe that this is the problem area. A test you can do is to remove the large plastic air flow pipe between the bottom of the intercooler and the inlet manifold to check the amount of oil in it. It is normal for the inside to be slightly oily, as the TC shaft bearings float in a spray of oil. But if much oil is found, it means that the TC bearings have worn excessively for the reasons I have described in my last post. You have not set out what mileage the engine has done. If it is high, ie>200k, the bearings could be excessively worn because of the amount of use. Finally, you have not informed us if the engine oil level has been checked and gone down materially.

The mileage is 139,000. The problem with checking the oil level is that on back of the dipstick it shows full, on the front (face up as when it is removed), it shows at lowest level- on the bottom mark.
|

The TC should be good at the above mileage, providing the engine has been lubricated/serviced as I have described, which you have not confirmed. The oil level is at "full" when it is at the top of the hatched mark on the bottom side of the dipstick (when extracted), as you have reported. The full level should equate to ~ 5mm down from the top of the mark on t'other side of the dipstick and should be confirmed by 5 circles when the oil level comes on the screen.

a link that night explain what I mean. Video taken after dipstick has been wiped, by the roadside and after the car has stood for a couple of days.
youtu.be/j-PkgNYSl68. You might not be able to see it but it shows half full on one side, but full on the back side.
|
|
I have seen the link where it shows full at the top and t'other side is ~5mm down on the scale but not down to half full. Looks ok to me. You have still not confirmed if the full level appears on the screen when the oil check is requested after the start card has been inserted. As an aside, it seems to me that you can't have checked your oil in the past if you are only working out how to do it now! Could you also have only told part of the story here I wonder?

There has never been an oli level check light on on startup.In other words on startup the oil level has indicated Ok , on every start. I have relied on the oil check uo being ok. I only doubt the oil dipstick as I am confounded as to why the vehicle is behaving this way now. It has eerted a doubt that I maybe at fault.In the past the oil was checked by the service mechanic. The last oil change was 32 months ago and when I last checked the oil level it read the same on both sides. i belive the extraction of the dipstick draws latent oil which is held inthe dipstick tube as you drag it outand gives a false reading. I belive that the upper face is the true reading.. Another reason why renualts are idiosyncratic and so crap that a basic oil level reading is confusing by design and I wish I never bought this piece of crap.

No oil check "light" comes on but, as you know, an indication of the level ( >5 roundels) comes up on the screen start sequence and when you press the button on the stalk to go through the cycle. The oil level is easy to check and the dipstick is like any other if you understand which side shows the full level, which l can confirm is on the bottom side. I don't recognise your description of Renaults. The engines are actually very good evidenced by the fact that they can keep going for so long without even an annual oil change! But, as I have explained above, they must be lubricated and serviced properly, like any other engine, which is also set out in the handbook. I am afraid that yours appears to be a classic case of excessive TC bearing wear caused by lack of proper lubrication. Best of luck!

You call yourself maintenanceman and admit not changing the oil for 32 months. No wonder you have a problem, this is way beyond any limit even for modern oils and specially for a turbo diesel where the oil gets highly stressed.
Suggest you stop wasting everyones time and accept has failed through lack of maintenance and that now you need to pay out and fix it or scrap it.

Why is it that little details like 32 month oil change intervals never appear in the OP? Well, that's that little problem cleared up.
|

Beyond belief. Is this how forums fill up with horror stories?

No sorry that was a typo.It was meant to say 3 months ago and checked around 3/4 weeks ago. No cheap oil has been used. I think the last lot cost over £60,(1 x 5L and 1x 1 L) just for the oil. Sorry about the rant, I was just upset that now it's scrap.
