Hey how you guys doin out there? I have a question about my f-150's motor(4.9 300)...Sometimes when i start it up after its been ran earlier on in the day it makes a clanking noise for a few seconds in startup. I don't know what it is and i'm just curious because i've heard how good these motors are and i wanna hold onto it. Sometimes it does it and sometimes it won't. My other f-150 did it once or twice that i know of but i don't drive that too often. My dad said his 88 did it from the day he bought it brand new. Could anyone answer this one for me?? thanks alot...Jake
