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.
