anyone know of a place where i can get a lost motion assembly and a collar for a z6 head? all the junkyards want to sell the cylinder head as a complete unit.

 

dont only replace one. get them all its more money but its better this way.
that way you can upgrade them all.
besides i dont think you can only buy one. call honda.

 

Replace them all while everything is torn apart. Honda will sell them individually, but you should just replace all 4.

What they said ^^^. Just replace all of them... The dealer was the only place I could find them for sale..

 

Loosing a lost motion assembly....hmm...sounds sort of tricky.
How do you re-locate something that is by nature lost?
Very existential.

Just kidding. +1 for replacing them all with some from a junked Z6. You will be happy that you did. I was.
