how do i seafoam my 2003 f150 4.6 supercrew thanks in advance

 

I don't know how to post links to other post on here. Or if I even can I'm on a blackberry so its different from a computer.
I've read several good threads on how to sea foam.
When I clicked on your post one that you need to read is at the very bottom of the page. Under the similar threads.
I know I'm not much help but that should point ya in the right direction.

 

I know this will stir the pot but don't do it! Do research on Hydrolock, thats what could happen when sucking Seafoam into your engine. To get carbon build up out of your engine takes physical effort with wire brushes and sometimes more.

 

Interesting. I haven't read anyone saying don't do it. This could get good !
I have never done it and honestly never really heard about it until I joined here.
