It clears out some things. I recently did mine along with a tune up. It wont hurt anything to do it though, if anything it may clean out some carbon deposits, sludge etc.

There are definitely two schools of thought on this - for and against. For myself, I successfully used Seafoam on my Mustang GT with no ill effects. One-third in the gas tank, one-third in the oil, one-third in the intake.

It didn't set my world on fire, but it made me feel better about maintaining the car, which has almost 150,000 miles on it now.

I like gunk where it is except during an overhaul. With good reason.
When I was a kid my dad bought a Ford pickup, 6 inline. Didn't know what kind of oil had been in it so he started using Havoline. After a while it started using oil and smoking. Didn't have that many miles. Tore it down. Obvious that it was sludged up with non-detergent oil and the Havoline detergent was cleaning it off. Like the pushrods covered with gunk with an inch clean on the top end where the oil flow was washing them off. Good, huh? No. That much crap circulating around was enough to plug the filter (which he changed often) causing it to bypass and circulate the dirty oil. Oil rings on the pistons clogged with the gunk and stopped lubing the cylinders.

This was an extreme case but illustrates the point. Some engines with problems come apart clean, some dirty. I don't know what the crud buildup hurts but I'd rather leave it where it is than put it in the oil stream.

If you pour the sea foam into the crankcase like you pour oil into the engine.
It cleans it all out. That is why it is vital to change the oil after doing this. It will clean all the gunk out of the engine/oil passages.

Yeah I would only put that stuff in the crankcase if I was about to do an oil change.
