do you mean that the VANOS seals work is useless unless I install the rattle repair kit, in my case?270,000 miles!!! Wow!
Would you say that the noise is a rattle? If so, consider installing the Rattle Repair Kit: http://www.beisansystems.com/products.html
I think the noise of my vehicle is having less frequency & also not continuous, will be there for one or two minutes then it will disappear. Will check it further & will provide update here ***8230;
