Fitted a new catch can today along with re-doing the pipework as it was a right mess (my bad from the first attempt haha). While i was at it a noticed a half moon shaped hole in the side of the cylinder head, i could get my little finger in it but it seemed to be sealed behind from some metal object, now it looks like where the AMK/BAM vvt tensioner goes but not sure, anyone with a APY engine give me a heads up?
