Cam Towers

[viparz]

When I removed my Cam Towers from my old head there were guides that half sat in the head and half in the towers, ensuring that it all lined up straight. Is this their actual purpose, I noticed that a couple of them were missing?

If I installed my head without all of them, would I be doing my Z a great injustice? If so, where do I get them from.

Thanks in advance

Viparz,

The dowels are required for alignment of the cam bearing towers. Upon removal, they will sometimes they stick in the head, sometimes in the towers, sometimes in both. I ordered new ones from Nissan a few years ago, and they were still available. L24/L26/L28 all used the same part.
