A friend of mine recently picked up a used one and is going to go through it. He seems to remember that the ZZ3 crate engines from GM had some sort of inherent problem (valvetrain?)

Anyways, he wants to address it durring the rebuild.

Anyone hear of a problem with those crate engines??

Thanks!

They use a plastic timing cover... but you can just install dowels and install a conventional timing cover
