Piston Slap: Less Slap, More (oil) Control

Pete writes:

Hey Sajeev, I got one for you.

Several engines nowadays are set up to operate on half their cylinders under light-load conditions. Would the design considerations for piston rings vary from those normally used for such cylinders that are only used part-time? The question arises in the context of a 2009 V6 Accord that is currently in the Honda dealer’s shop to have the piston rings replaced at the manufacturer’s expense to cure a continual oil consumption and spark plug fouling problem.

MaintenanceCosts If only it had a hatch. The Model S is so much more practical, has similar performance in non-Plaid form, and is $20k more - and the $20k premium seems almost worth it just for the hatch.
Lorenzo I'm not surprised. They needed to drop the "four-door coupe", or as I call it, the Dove soap bar shape, and put a formal flat roof over the rear seats, to call it a sedan. The Legacy hasn't had decent back seat headroom since the 1990s, except for the wagons. Nobody wants to drive with granny in the front passenger seat!

Vatchy What is the difference between a car dealer and a drug dealer? Not much - you can end up dead using what they sell you. The real difference is that one is legal and one is not.
Theflyersfan Pros: Stick shift, turbo wagonExtra tires and wheelsBody is in decent shape (although picture shows a little rust)Interior is in decent shapeService records so can see if big $$$ is coming upCan handle brutal "roads" in Uganda, Rwanda, and Tanzania, although the spare wheels and tires will be needed. (See picture)Cons:Mileage is high Other Volvos on the site are going for less moneyAnyone's guess what an Ontario-driven in the winter vehicle looks like on the lift.Why wasn't the interior cleaned?Clear the stability control message please...Of course it needs to cross the border if it comes down here. She lowers the price a bit and this could be a diamond in the rough. It isn't brown and doesn't have a diesel, but this checks most TTAC wagon buyer boxes!
