I have a 2013 3.5l ecoboost I want to remove the throttle body to clean it is there a gasket on the back side the at I need to replace after cleaning or is it reusable if there is a gasket

 

Bump

 

There was no gasket on my 5.0

 

I have a 5.0 with the gasket. All data does not specify which engine, but it does say to discard the gasket.

 

hmm maybe that's why I'm getting a whistling noise haha wonder where my gasket went!

 

they should all have gaskets and you should always replace them.

 

My truck is nearly at 80k so I cleaned my TB last weekend. There is a little gasket in there. I just wiped the area and it still looked in good shape so I left it.

Wouldn't hurt to replace it though and I believe it is "recommended" to throw a new one on anytime you clean it. But I haven't had any problems
