Ok well it's time to rebuild my 06 510. It has a tad over 12,000 miles and never let me down. I figured I would give her a complete rebuild including a 530 kit. I took all the pics to use as a reference for assembly but maybe it will help someone here.
Do not pull on the oil line it is held in by the cam holders
Remove the cam holders. Do not mix them up but they are numbered 1-4
Set them aside for now.
Remove the 4 head nuts AND washers. You will need to turn the engine upside down to get the washers out.
Remove the cam chain tensioner
