I finally found out what the obnoxious rattleing noise coming from under the hood was. The timing chain tensioner (upper or lower?)
is worn out and it makes a terrible noise from under the valve cover near the timing chain area. Does anyone have experience with this and is looking to make a little money on the side. It needs to be fixed right away cause I have let it go for about 3 weeks now and the noise has increased severely. I would like to do it rather then take it to a shop so I can get a feel for the engine but I am unfamiliar with Nissan and have never worked in the timing chain area before. Anyone who might be of some assistance please let me know?
