Hello.
Sorry for my bad english  My 7afe have been smoking blue smoke for some time now.. and the smell of oil is present almost all time (USE ALOT OF OIL!)... It smokes never when idle, only when i give it some trotle. i have been thinking it may be the Valve seals, but it might be the piston rings aswell... what is your opinion? |

What happens with the rings is that the oil control rings end up stuck to the piston and let oil into the combustion chamber. Piston soaking and running an oil flush usually frees them up enough to where the burn is very little if at all. More or less ALL 7A's do this, it's just a matter of the severity of the burning. So that means they've been running and driving for years this way, so it's not going to hurt anything outside of spark plugs and the emissions equipment. Trust me, do the soak and flush and change it out to 20W-50 and that should help significantly.
