Default Vernier slipped!

The adjustable venier has slipped on the inlet side of my 4x4 cossie and has become very laggy and the allen bolts where done up tight, is it just a case of loosening up the allen bolts and setting it back to zero or is it a case of re-timing it again?

Cheers

Rand

safest thing would be to check the cam timing from scratch
