Hi all, I have a 1998 XK8 with noisy VVT's and would love some help with tracking down new ones as my local dealer says that they are unable to get them anymore. Thanks Mark.

Hi Mark and welcome to the Club,

Try the David Manners Group,  who are Jaguar Specialists,

Failing them Rimmer Bros or Barretts,

Is it the variators that are noisy? If it is then in my experience it's often an oil circulation problem as it's usually oil pressure that actuates them. Dirty oil, oil that's too thin or low pressure for any number of reasons, including things as simple as a blocked actuator pressure valve, can cause variators to rattle or lock in one position etc.

Of course they could be faulty, but if both (or all four? I don't know the XK8 engine) started rattling at the same time then I would look for another cause.
