Sea Foam

Just curious has any one used Sea Foam before and is it as good as the reviews say it is. Also, can any one tell me where the pcv valve is located in a 2004 F150. Apparently according to the directions it is supposed to be sucked threw pcv valve, added to gas and oil tank 1/3 in each. Does any one know where this valve is?? Thanks

I have used Sea Foam. Did it do any good? I really couldn't tell you. I read that a lot of people have used it without any problems. I put a can into a full tank of gas and run it through.

I wouldn't put that stuff in the truck

Seafoam is great for Carb'd vehicles...but do you really want something that caustic and nasty in your motor and electronics.

You hear good stories about the stuff, but there are lots of guys who have had Seafoam cause damage.

FWIW, Ford themself specifically says not to use additives like Seafoam. I'd trust their judgement

My experience with the stuff has been real good. I've used it in both my Expy's, my 'Stang and my F150 for rough idle, injector cleaning and just general internal conditioning. I run half to 3/4 a can through the brake booster vacuum line, 1/4 in crankcase (then change the oil a day or two later) and a full can in the tank. Do a search and I'm sure you'll find lots of info; lots provided by myself, so I won't bother repeating myself.

But, as Tylus points out, not everyone is comfortable with it.

PCV Location

If you have the 5.4L 3V Triton the PCV valve is located inside the valve cover and is not a replaceable part without replacing the valve cover. There is a line, rubber, I think that goes between your PCV and throttle body/air box.
