'01 f150 4.0 knocking at idle in gear
180k miles, it does it when its warmed up, in drive, when it gets to some off idle rpm its gone, i pulled the fan and shroud apart and am using a noise detector and seem to get it from the front more, its like a rod knock, when cold sitting overnight, it starts quietly, until its warmed then the noise returns, its a 4.2 v6
