Hi all,

Just wondering if anyone knows of a product that will clean away carbon from the top of  the pistons without having to pull the engine appart.

I have heard their can be a build up and i thought it would be a good idea to give the pistons a clean just incase.

Cheers.

Do a search on Subaru upper cylinder cleaner, and also "Seafoam"

So maybe run the Subaru Upper Engine cleaner through (Makes a shit load of weird smoke. I remember seeing them do it when I worked for Subaru) and then change go for a ride, then change your oil to clear the contaminants.

Thanks for the advise I will look into it.
