P0014 P0017 P0011 Timing Codes on VVT 5 Cylinder (cams over advanced and not sync'd)

[777funk]

My son's first car (04 XC70) was bought running great, but using coolant due to a blown head gasket and warped head.

We fixed this and still is running great, but giving us some codes.

We rotated the engine several times and all marks line up (as well as cam locking tool). So I think that means it's in time.

Where might we look to solve this?

I should add that we also notice the oil pressure light flicker occasionally.

The cam timing has to be reset with the VVT units clocked hard counterclockwise per the VIDA procedure

I’ll try find the link

I was thinking the VVT pulleys needed to be turned fully clockwise to the end of rotation (with cams locked) before the belt goes back on. Is this incorrect?

If I'm understanding you correctly, I may be in errror. I was under the impression that with the cams locked, the cam gears should be turned fully clockwise before the belt is put on. Is this not correct?
