I'm in the process or performing the 105,000 mile service on a 2003 V70 non-turbo. I see the marks on the cam sprockets (on the outside) but nothing on the inside to align with at the head. I believe the cam sprocket markes are to be vertically aligned with the engine but not sure, the belt slipped and I lost my cam reference. There is a "V" on the pulley that appears to be at the bottom and what looks like a mark on some device behind the pulley which seems to align with a small casting mark on the block. My belt slipped with I was taking it off and I am somewhat confident the crank marks are 'right' but I am not sure how the cams are referenced from.

Thanks for any and all support or advice.

For the Cam marks the top timing cover is the refrence for the marks. Slide the cover on and line them up.
