As above loosing a few litres every few 100 miles, problems not got any worse although a hazard waiting to happen, sourced leak which appears to be the oil return pipe that goes in to top of turbo as elsewhere looks dry

I've nipped it up but it didn't budge so must be tight...

Brings me to the o rings... Had a mobile mechanic change by turbo away from home so didn't see the work being done, and I think the o ring must have either been stuck on the old turbo or it dropped out or a number of things..


Brings me to this, I paid £6 odd for part number 7701471740 from renault, now when I undo the feed pipe and replace the I ring do I need to prime the turbo then? As it's a used turbo and should be full of oil or lubricated anyway.... So do I still need to prime or can I get away with changing and tightening back up?


Also having a whoosing in the passenger footwell... Was like it before turbo was done and after... Torque appears to be down a bit aswell, not much but I can notice it's not pulling like a 1.9 dci should.... Mpg and everything else appears fine, maybe a split on the pipe work on that side? Is there anything common? As pipe work appears to be plastic and is the air pipe (to filter)

Thanks in advance

Assume you changed the turbo cos old one failed? Was any other work done to work out why it failed so that could be put right before new turbo was fitted?

Hi

Not sure why turbo failed, the centre turbine was knackered

Apprantley egr and all associated pipe work was cleaned, I beg to differ tho.

Now appears to be leaking from the oil return so was wondering if I need to re prime or if it's a case of undo, new seals and tighten back up?

No, you don't need to re-prime it in this particular case, just keep the engine on idle for a bit longer the next time it is started.

I'd take the intercooler off at some point and make sure that's clear - just in case that was skipped. Quite easy once the bumper is off.

Mine had a refurb Turbo 20k ago and it continues to use oil - not loads but enough to need a monthly/1k top of of 250ml ish. When I had two bikes on the back on a 230 mile motorway trip it used 100ml and most of this ended up in the intercooler as far as I can tell. Were the car worth more I would get the turbo off and refurbed again but turbo repair companies seem hit and miss so there is no guarantee I would be any better off...

Otherwise runs fine generally. New EGR has settled the rough idle for now at least.
