Engine oil flush in a 00RS, good idea or bad?

If the engine has many miles on it, then the answer is "nay"

The block has about 40000Kms and the valve train has 165000. Why nay?

 

[Richard L.]

The engine flush will remove sludge/buildups from nooks and crannies, thus opening up the possibility for an oil leak if the block is dirty inside.

Ok so i have a question is it better to start doing flushes/seafoam early in an engines life and keep up with it or is there some magic mile number. Same goes for fuel injector cleaner etc......if that stuff really works. Fyi my 05 rs has 21k miles on it what would be a good "treatment"?
