C5

[Marshy]

I have a 2002 C5 2ltr HPI Exclusive SE which I have had from new. Although the engine was noisy from new I was told that there's no problem, it seems to now be more noisy and when cold it ticks over like a diesel. As far as I can tell the noise seems to come from the the engine and sounds as if the tappets need ajusting but these I believe are hyd type.

Has anyone had this problem and did you get it fixed?

regards

Sorry - a quick read of your post lead me to believe you had an HDI - so I've deleted.

The noise you are refering to is probably the camshaft variable valve timing unit......theyonly have it on the hpi

 

Its fitted on the inlet cam and can be accessed under the timing belt cover once the belt has been removed.

 

It requires oil pressure to control it, however inside it it has a couple of seals that can leak and allow it to rattle and make it sound like a diesel.

 

Rather than start taking it apart you might want to drop by your local dealer and let them have a listen......if it is this component that has failed they will recognise the sound and advise you accordingly
