So I noticed a leak coming from where the passenger side valve cover meets the head. So I went to the dealer to pick up a new gasket and spark plug tube seals. When I went to remove the valve cover bolts, they all unscrewed with virtually no resistance. The Haynes manual says the torque specs for these are 53 in/lbs which obviously is not very tight at all, but these almost seemed like I could unscrew them with my bare fingers! Got me thinking that maybe this is the reason I'm experiencing a leak there. Nevertheless, I'm still going to replace the gasket though. Anyone else have a similar experience? Also, the valve covers have never been removed before, so it's not like someone was in there before and forgot to tighten them down enough.
