I seafoamed my 5.2 yesterday two different ways. Did half the can through the brake booster vacuum line to the intake manifold, and around 4 - 5 oz in the throttle body.
It smoked like crazy, which is always a good sign. The thing is, before seafoaming the engine, I've been having a steering problem where the steering gets insanely difficult to turn when you are at a stop or real slow. I know it's not my VC because I don't have wheel hopping.
Anyhow - after the seafoaming and letting all that crap burn out, I noticed my car is not locking the steering up as bad, it's like 70% more easy to turn now.
What I'm wondering here is that is there a vacuum line that goes to the power steering pump or something that provides vacuum to assist steering and could've been cleaned out when I seafoamed yesterday? The power steering fluid levels are fine, and were not touched.
