your wish is my command:
Go to Ack's FAQ (the link is in my signature) and do a search for
fsm. Since you are probably talking about an 8-valve G16, you can use the engine section of the Samurai Factory Service Manual (fsm) to disassemble the head and remove the camshaft. That information is in the first section at the top of the page.
If I am incorrect (and yes, it happens...

) and this engine is a 16-valve, go to the Tracker FSM link and select Section 6A from the list for teardown instructions.
Hope that this helps!
