Noisy,rattling 2.5 crd engine
 

Hi guys

I have had my voyager approx a month now and I am not feeling too confident with the engine. I had a few issues with a smokey engine,after an oil change that seems to have resolved itself. The exhaust back box was rattling and tickover,a new exhaust sorted that. But my engine sounds a bit noisy,with a metallic,rattling noise on tickover or when revving the engine. Could it be the manifold? I know the car had a replacement turbo recently,would they have removed the manifold to do this? Or are they just a noisy engine?
Any help would be appreciated
Thanks
John

Sounds like something has worked loose....a heat shield or something.

By todays standards I find the 2.5/2.8 CRD engines are a bit loud and rough at idle, although when cruising on the motorway mine seems alot smoother.

my voyageri the same as yours : bit loud and rough at idle, although when cruising on the motorway mine seems alot smoother.;););)

I've had injector issues recently and when one of them was a bit worse than just leaking slightly, it was giving a rattle like tappets can.

Take the engine cover off and see if theres any carbon build up. May also show up as exhaust fumes or diesel fumes inside the car.

Thanks guys,
I have tried putting injector cleaner fluid in the tank,millers on the first tank and wynns on the second. Neither seem to have made any difference. I have also changed the oil again and tried adding a tin of Ammtech Engine Restore to the oil (this stuff worked wonders on my Vauxhall Combo Vans).
I took the car away this weekend,about 120 miles down the M4 and it drove fine and pulled well,even with 4 adults,3 children and luggage.but when I pull off from traffic lights and accelerate hard,there is quite a lot of black,sooty type smoke initially,then it clears.
I will stick with it for a minute,keep you posted and maybe get a diesel specialist to take a look. I thought it maybe an injector? Or I had this on a Saab TD and it turned out that the timing was out on the fuel pump slightly (I think it was slightly to advanced and gave over fuelling)

Thanks again
