Z18 Valve cover on a Z24 engine

[Manykarma]

Ok, so I just found out that the Z18 engine existed lol. I’m still learning of all the engine these truck came with. I love the way the valve cover looks with the Nissan Turbo lettering. Would I be able to swap my steel Z24 valve cover to the Z18 one? I just bought an aluminum Nissan Z valve cover but I kind of want to sell it now and buy the Turbo one. Are there any fitment issues or differences? Also, the one I want to get seems

There are no differences.  Heads are same shape.  I think spiff has one in his z22 turbo

Just an fyi, the aluminum valve covers and the stamped steel ones do not use the same gasket. The aluminum ones use a flat cork gasket and the steel ones use a solid rubber shaped gasket which is vastly superior IMO.

The bolts are longer on all cast aluminum covers than the steel ones.

 

I suspect that the Z18 uses basically an old L18 block and internals, just like the Z20 uses basically an L20B block and crankshaft.

The Z20/22 aluminum valve covers use the same bolts as the L16/18/20 valve covers and the same as the inline 6 cylinder aluminum valve covers.

You will have to source a valve cover from overseas. Most commonly seen in Japan or Australia expect to pay $250++

Australia may have one but it would have been imported. Z18ET was a Japanese domestic option. I think they look cool.
