I've posted a couple threads and have had lots of visits but no replies am I doing something wrong?? Please Help

 

Wrong? Not particularly.

You're under warranty and working with a dealer. No much anyone else can do.

However, you can educate yourself about what the dealer is talking about so you can better understand possible issues and whether or not the dealer is correct.

SEARCH the forums for "piston slap". It's very common.

Also, read the full-text TSB to see if it applies to your vehicle. It's available on a different F150 Site:http://www.ford-trucks.com/tsb/fullt...php?tsb=06-4-7
