I couldn't find any posts or even comments on the topic on this bulletin board.

My 1980 242 DL has 134k miles, is in storage, but didn't *seem* have have problems, such as oil burning. I'm unsure when I'll take it out of storage, but I've been keeping it maintained for that day and would like to do so. Looking through the spark plug holes this afternoon, I can see that the piston crowns are full of carbon soot.

Other car owners, especially Saturns and 1998-2002 Toyota Corollas, do a piston soak to clean the piston oil rings and piston oil passages, which get gummed up and cause oil burning. Most report success with reducing oil burning. Chemicals used include Berryman B12, Marvel Mystery Oil, and kerosene. These are exclusively 4 cylinder vertical engines, which lend themselves to even distribution of the chemicals around the piston oil rings.

My B23F engine, like most B2** engines, sits at an angle, so I'm unsure as to how much even penetration of the piston rings will occur if I pour chemicals into the combustion chamber.

Thoughts?
