Hi, Just completed a 250 mile motorway run last night, when I got to my destination, I noticed that the engine seemed to be knocking loudly when blipping slightly above tick over, but disappeared when revs raise above around 2000 rpm, the noise was very noticeable and my first thought was camshaft or small end, but when restarted later today despite running the engine for 20 mins to warm up I was unable to replicate the fault. Any advise what this can be.
Also, the engine seems to produce a noise which sounds like pre ignition on a petrol engine at 2200 but disappears when revs rise, anyone else experience this or is it a regular characteristic
And finally when the engine is on tick over, after about 40 seconds it runs lumpy, as though one injector is intermittent on tick over, anyone with ideas on this also?
Thanks in advance
Jon
