Re: '03 E350 5.4 WTF is this noise? video included
It's definitely coming from the right front corner of the engine. I can NOT hear the noise through the oil fill tube. I had a guy at the Ford dealer listen to it and he said he could hear it through the oil fill tube and that it sounded like a cam chain tensioner. My neighbor owns an auto shop and he said cam chain tensioner. I didn't buy that but after listening to it for all this time I started to worry. In the last month it started to sound worse. Last weekend I replaced both cam chain tensioners. This 135k mile motor is very clean inside and the chains and guides look perfect. The noise is still there. The problem with pinpointing the noise is you have very little time to listen because it goes away in 10 seconds or less. Then you have to wait at least 5 minutes, sometimes 10, for it to do it again.
