2014 2.2 Diesel rattling under load

Postby Little Mark » Wed Nov 21, 2018 12:12 pm

My 2014 103k 2.2 diesel rattles really badly at start up but it largely settles down after 5 minute warm up. When it has warmed up you can rev it up stationary and it sound fine and likewise if you drive it normally. If you give it some stick the rattly noise comes back and sometimes it sounds like the top end has no oil. Really worrying as you can imagine.

The van is new to me but I have changed the oil and filter (seemed to make it worse), air filter and fuel filter. Does this sound like an injector issue or is the timing chain loose? Any pointers would be appreciated. Thanks.

I still haven't fixed this and I got the time today to take the engine cover and sound deadening pad off and there is Diesel everywhere. I can't see it bubbling from any joint but the lip at the front of the rocker cover is full of diesel, there is Diesel in the injector recesses and over the injectors and a light covering all over. Obviously I will have to clean it all down tomorrow but any pointers for a leak on the injectors/high pressure line. Anything common to leak here on these engines? Thanks

I didn't think that the later engines suffered from this, but have you checked the tightness of the injector clamp bolts?
It's the small headed bolt bang in the middle of your first pic, but don't be tempted to overtighten it.

Regarding the leak,Check all the injector pipe unions,or there are some small O rings where the leak off pipes connect to injectors.
That will not cause the rattling though,
If it sounds like 'diesel knock' best to get pcm updated to latest level first,
But what it needs is injector pilot correction learn routine,to cure rattling.
