Hi Guys, new to forum. I have a 2002 Deville 4.6L. While replacing the valve cover gaskets I noticed that the timing chain on the pass. side back towards firewall seems loose. it was drooping with quite a bit of slack. Is this normal or do I have a problem. I realIy do not here anything out of the ordinary while engine is running. Oh yea, one other thing. After the car is turned off their seems to be a rush of air somewhere by the intake. Only does it when it is cold. if so how do I fix it? Thanks.
