Just tearing a down a 1.6 16 valve that threw a rod. to take the head off it looks like I need to remove the cam..... do I? and what size is are the hex head bolts? Also if you know is the water pump pully same on 8 valve and 16 valve? And I guess I will keep rambling with all my questions. Distibutors listed on ebay all say 1.6 liter 8 valve, is it the same distributor as 16 valve? Thanks, Sami Jr.
