[QUOTE="k-rub, post: 1298449, member: 21298"] I had two different rattles going on last year. One was at startup that went away pretty quickly. The noise originated from the top of the motor. I went in and asked them to check for PCM/TCM updates. They updated both and the top rattle went away. Haven't heard it since. The other rattle was a similar sound but was coming from the lower part of the motor and I could hear it next to the wheelwell mostly on the drivers side. This noise didn't go away. It just kept rattling even after warm. I brought it in, the dealership diagnosed it as cam phaser rattling, and they ordered the parts. The day before I dropped it off to get fixed, my new SP 592 spark plugs arrived. I installed them and that rattle was completely gone. The truck idled, started, and drove much better. I cancelled my service appointment and I haven't heard any rattles in over a year. The dealership thinks the rattle may have been spark plug knock. I had run a 5Star tune for a short while. I think the tune fouled the stock plugs because they were super burnt up. The new plugs made everything much better. I have a catch can and the EBOV is vented to air now. I don't get a whole lot of oil buildup in the can but I do get oil residue on the top of the skidplate where the EBOV points. No hesitations and no rattles. 31k miles and I beat on this truck pretty good. Now the transmission is an entirely different story... [/QUOTE]
