CDTi loud metallic noise when idling:
I'm not having much luck with the silver surfer currently! It has suddenly today developed a loud metallic rattling noise on idle.
The noise goes away as revs increase, and there is no loss of power or any other change that I can detect. Any ideas chaps? Is this consistent with one or more engine mounts failing? Sent from my iPhone using Tapatalk |

Could be your crank pulley - does the noise seem to come from near the offside end of the engine ?

Hmm, not a million miles away but more metallic sounding somehow. Also on this video the sound seems to take a few seconds to kick in - mine is straight away from start.
PS should have said I had my pulley and all belts done two months ago, so not that I think. Sent from my iPhone using Tapatalk |

Tom- do you know what make of pulley was fitted ? - anything other than the genuine Corteco item can fail quite quickly.

No it's not a Corteco, unfortunately. It's by a French manufacturer from memory - I will have a look on the invoice. I have done less than 2k miles though since it was changed, can non-genuine ones really fail that quickly? Annoying if so but I shall be straight back to the garage!

Also worth checking the water pump pulley for play, as that can make a similar noise when it is on the way out. |

Lack of funds and needing one quick I had one of these fitted last October and it's still going strong...although to be honest I've only done a few thousand miles since.
Comes with a two year 20k warranty anyway so if (or when) it does fail I'll replace it with a genuine Corteco one. https://www.ebay.co.uk/itm/321209234685 EDIT: If you do need one and go for it they don't come with a new stretch bolt so you will need to get one. I got one from Rimmers.

Sounds exactly what I had just a couple of months ago, bottom crankcase pulley broken. mine sounded like timing chain rattle or cam belt tensioner rattle, sound went when engine was under pressure, only sounded once you took your foot off the gas and the engine was just ticking over but it was the bottom crankcase pulley.
