Sound out of oil filler cap
In this clip (not my car) you can hear a noise out of the valvecover.
Now my engine has sort of the same sound. My gutfeeling is telling me there is something wrong. To be precise: A broken rocker or tappet or a not completely sealing of a valve. I also heard and read that more diesels are a bit noisy and some of them had bad tappets/rockers. Before i will inspect the camshafttrain ill do a forte engineflush for the remote chanche of a clogged tappet. For my curiousity: Does anybody else heard this noise out of the oil fillercap? Or want to check it ? |

Nope no paranoia
If this sound is normal, how can it permanently disappear after an engineflush and new oil? Completly silent now Last edited by 5cilinder; Nov 26th, 2011 at 18:56. |

My D5 makes about the same noise, has done since we bought it. Maybe a little bit of diesel knock, not currently worried about it.

I have the d5 185 version and my sound is more of a deep popping sound and certainly louder than that shown in video . Keep bonnet shut when running and you wont here it !

I reckon it`s crankcase pressure moving pockets of oil that gathers in head casting webs around myself. Likely nothing to worry about.
