I would like to find a solution to this as well. I have replaced all three chain tensioners and the vario cam tensioners and pads (for other reasons). I have a new oil pressure release valve to install. If anything I think the startup rattle is worse after replacing the tensioners. I also installed a spin on oil filter adapter.
