BAM

is it stamped somewhere on the motor? just curious cause i always thought it was ATC but i found out it could be something else.

 

All 2000's are ATC engine codes. Its also stamped on a tab by the timing belt off the head

 

Mean anything in particular if its NOT stamped there. Mine's blank. I know what it is, just found it curious that its not stamped.

 

Either its a replacement head or they skipped that part on yours. I have no idea honestly
