how to seafoam a 4.7

[SwollenMonkey16]

I just got a 2008 work truck and was thinking about seafoaming it. I put up a post in the 3rd gen section but no answers. Anybody have experience? Any tips?

Easy; don't waste your time...

What would you recommend

What's wrong with it?

Nothing. It's got 202k miles on it and it feels a little sluggish. I just want to make sure to keep it as healthy as possible

Chevron Startron. Every oil change, for a few oil changes. Then every other oil change.

NEver really thought much of that kidn of stuff but Chevron Startron has made me a believer.

Take a look at the owners manual. If it doesn't have one in the car, look it up online, and make sure all of the maintenance is up to date.

Seafoam is somewhat of a placebo (their fuel stabilizer is ok, but other companies have better products for that). Using seafoam likely won't hurt anything, but it has been known to occasionally foul (newer) spark plugs, and (rarely) displace carbon deposits from the top of pistons, to their ring lands, creating a potential hotspot, and potential ring land failure - meaning the engine needs a rebuild. Normal engines are designed to handle some carbon buildup on the top on the piston, and elsewhere in the upper combustion chamber. If the inside of the combustion chamber is absolutely disgusting, it's likely because the vehicle hasn't been running well for a long time, which obviously needs to be addressed first.

Seafoam won't really "fix" anything. It's a cleaner (a very mild one at best). Think of it (and all the other magic juice products) as preventative rather than reactive. If it helps you sleep at night, go for it, but it's foolish to think it can replace real maintenance/repairs because some random youtuber posts a video of his whatever being cleaner, and all his vehicle's issues are now fixed thanks to Seafoam.

Example - Random person: "I have excessive oil/gunk buildup in my intake manifold. Seafoam cleaned it right up."
Me: "why does your engine push that much oil through the PCV/crankcase ventilation into the intake manifold? Maybe your engine has excessive blow by..."

See what I'm getting at?

I may give chevron fuel system cleaner or lucas deep clean a try

While you're in there, pop a spark plug out and take a look. Check the air filter too. Both are easy to check, and change, and are the leading causes of running rough / getting ****** MPG.

It works for correcting issues like rough idle/running. I used it on my 99 sport.

Be courteous and do it somewhere the neighbors won't get upset.
