yeh looks like water/coolant stain.... I slightly over filled my coolant recovery tank durring one oil change and as the truck ran, it purged out the extra on mine once and the cooling fan blew it in the same spot of the ccv cover as well, I think it does it with rain and car washes as well? but just my thoughts ,haven't had a camera under the hood to see it happen? its just what it looked like, that area and the brake master cyl. area seem to always get dirty and need cleaning off, and the dust from the under hood insulation is a pain as well. if any one finds out for sure i'd like to know as I try and keep the under hood parts as clean as I can.

I tried to tow my 5x10 trailer yesterday. The 4 pin plug is hosed. I have an appointment with the dealer on Monday. Its on the list ...

1. 4 pin connector
2. MAKE SURE G30 was done (yeah right) thats why I prompted squid for the part numbers if known.
3. TSB 14-003-09 --- I cant get the entire full read TSB ... Id like to throw this one on the service desk.
4. The truck feels restricted at times / kinda flat.
5. clean turbo TSB ... found it once but had to log off and I lost it.
6. Whats this white crap.

So the list is growing.
