Well, its a 2001 f150 4.6l, first time posting new member be easy. Good truck starting to flipping rust. Ha! Anyways, Noticed one day as it was idling blueish smoke out the pipe and was starting to run rough, so i pulling the intake manifold, lower intake had sitting oil it. Further, the intake ports black, so last Saturday brother and i pulled the motor through the engine bay, hood off, All day and half of sunday. After work today I pulled the valve covers off camshaft checks okay, oil pan comes off and the whole bottom of the pan is covered in this gold/copper flakes. What is this from?

 

dono if a 4.6 uses em but connecting rod small end bushings maybe?

 

Trust bearings are gold plated (kind of brass) in CAT diesel engines... i thing gas engines use the same type of material. You should go further to dealership..
