Okay I Just bought an automatic 2001 sl1 engine and started to fool around with it. Just for fun. I was wondering if different cylinder head years are compatiable with others. Ex. 2001 with a 2000 or vise versa. I also took apart the cylinder head and noticed a little groove. I was just wondering what it does and if there was any importance. Like is it used for water or oil. Is it possible to just bore it down and get rid of it all together? I also wanted to know if the rocker arms are adjustable?
Awaiting your reply,
