how to clean out sludge in an engine?
Hi Gents,
I keep hearing about the stuff called "seafoam". Exactly what is this stuff and how does it work? Is it some sort of super cleaning agent? I have never seen this stuff in Pepboys or Autozone, so exactly where are you supposed to buy it? Also, if you buy you it, how do you use it? by adding it to your engine oil? By pouring it into your fuel tank as an additive to clean fuel lines?
If this stuff is useful in cleaning out gunk in a motor, does it do any harm to an older engine, such as mine with 146k miles, where tolerances/rings and so forth and no longer like new?
Any info highly appreciated.
