Help - is it VVT or chain tensioners
#21
As the rattle is only 1-2 seconds on start-up, I am inclined to point to the VVT locking pin as the cause. Oil pressure forces it off its seat on start-up so the VVT can start operation. If the VVT is not locked on start up, the vanes in the unit could clatter against the housing until oil enters the VVT under pressure, and this will take about 1-2 seconds.

Early XJ8 VVT Noise
Hi Guys
I'm new here but not so new to Jags!
I recently got a Daimler X308 1998 with the early type VVT, i have it stripped down and want to know what i should be looking for regarding the VVT noise?
It's only done 52k miles and needed a good service which i have now completed with a engine flush, the noise is still there and being a techy myself I am 100% sure it is the VVT, i just have no idea what i need to do to fix this!
Is it just a new seal someplace or something more serious? Any help very much appriciated.
Kind regards
David
