Ok so a little history first. Engine had a top end knock so I tore the top end apart and found a broke lifter. So while heads was off had them checked bought new lifters had cam inspected it is good bought new timing chain and oil pump and put her back together. She starts and runs but I have a engine timing code. Can anyone tell me what the actual engine timing is supposed to be at idle. And if there is any tolerance on this

Thanks in advance
