4.6 engine knock!!!
Today I did a oil change on my 05 screw 4.6 v8 w/ 24000 miles.I have done all my own oil changes since I bought it new, will this affect a warranty repair. The engine sounds like a diesel at idle not right away. I have to let it warm up for a minute or two and then the noise starts. I can not hear the noise from the inside this maybe why I haven't heard it before. My oil is motorcraft with a motorcraft filter. If I raise the idle to 800 - 1000 the noise goes away (I had someone press the pedal while I listened) I have read other post all talking about the 5.4 not 4.6. I appreciate the help guys thanks!!

Maybe you overfilled it, although i doubt it. I'd take it to the dealership, and actually talk to a technician and walk with him out to the truck and show them, thats about the only way that the dealership will no whats wrong. Good luck.

yep, the 3v 4.6 is in the Mustang GT
the trucks get a 2v 4.6
sounds like you don't have enough oil in the motor, or you put too much into it.

I went to the dealer today and they told me that my engine does not have a knock. That it is normal and if the noise doesn't get worse with higher rpm's there is no problem. My neighbor has a 97 4.6 and his doesn't have a knock. I can not hear it inside my truck but outside I hear it. The dealer also said since I have done all my own oil changes any engine claim would be denied from ford motor corp. Does this sound like a bunch of BS? Should I go to another dealer? Looking for some advice guys thanks in advance.

Is the knock louder on one side than the other. Try listening through the wheel well and see.
My 4.6 has a knock at idle that begins about 2 minutes after startup. It will go away at 1000 RPM and above. My knock is on the left (drivers) side.
Dealer hear it, says it's not right, but I am out of warranty. I will drive it until it breaks, or I find a dealer who will take it like this.
