hi have a scooby on a 2000 and the cams sound quite rattly on the turbo side is this normal :confused: : also seams to suffer a lot of turbo lag will a dump valve sort this out and what one should i use ... i have done no mods

 

A dump valve wont sort out lag, But you shouldnt have any on a my2000 with a td04 anyway.There must be some other issues? Are you sure this noise isnt the up-pipe blowing?

 

sorry being thick here up pipe ? it just seem a little slugish some times to was goinging to put new plugs in and see what happens
