99SE
CEG'er
I have a 99 se with the 2.5l v6. I have had this noise for awhile now. Its coming from the timing chain side of the engine. It sounds like the chain is loose and is slapping against the cover. It sometimes goes away though. The higher the rpm's the more it goes away. I've been bad about trying to get it fixed and hoping that it would just go away on its own. "Knowing its not". Now my engine is making a loud knocking noise on the top of the engine. Its coming from the back side of it. It goes away under heavy acceleration too. Both noises are sometimes unheard completely then they come back. ITs so loud that I can hear it going down the road at about 25 mph sometimes with the window up. The motor runs phenominal. It has plenty of power and it doesn't miss what so ever. Doesn't burn any oil at all. It has 66,000 miles on it. It seems like it just started an oil leak at the front of the oil pan under the crank pulley. I don't want to replace this engine already. Damn I just bought a new fusion and I don't see that I can afford an engine right now. The gas mileage is great. Its getting 27-28 mpg highway. If it didn't make those noises the car would be perfect. I love this car. It feels so good. Can any one help me with this problem? Has anyone ever changed the timing chain tensioner themselves? Please. this is my everday driver. Need help before it completely blows
