I live in Maine. My 2008 CTT, which just turned 150,000 miles, spent its first winter in a cold climate last year, and it was garaged all winter (and seldom driven). This year, I'll be commuting a couple of days a week, so it will be parked outside on some cold days.
More significantly, I'm considering not storing my 996 this winter, but instead keeping it garaged at home. My wife's Atlas takes up the other bay. The 957 would spend the winter outside. We get some bitter temperatures in Maine a few times a year, but generally it's just a traditional New England winter - cold, with plenty of snow.
With no signs (based on a look when valves were blasted last winter) or symptoms (noises, oil consumption, and so on) of bore scoring currently, how much should I be concerned about keeping the Cayenne outside and potentially introducing scoring? FWIW, my engine (9PAAI1) falls in the range of structurally honed cylinders for 2008, I believe.
OP - Shouldn’t a good 5w30 full synthetic flow enough to properly protect the cylinder lining? Could you find a friend with a barn or stall to park the 996? Then you can schedule winter time conjugal visits with it if you don’t sell it.
I'll look into a block heater, but I'd like to see a functional example before committing.
I could store the 996, but I'd rather have it nearby in case anyone interested wants to look at it. Besides, it's comforting to know it's there in the garage to peek at.
I'd say your odds of bore scoring will increase substantially with letting the engine get really cold repeatedly. If you plan to keep the Cayenne long term, I personally wouldn't do it. You could winterize it and keep it outside for the winter and not drive it (or the 996), but those really cold starts won't be good. It's just the engine we have in these things and we know what causes problems in them. Some type of engine heater would resolve the issue. I think.some came with a Website unit as an option. Maybe you can find a salvage Cayenne that had one and buy the heater setup. I think maybe Jeff Spahn has info on these.

I have the heater, but then again I park in a heated garage at home and at work. Car only sits in the cold on ski trips. Retrofitting the Webasto heater is quite a job. Like take the car apart type of thing.

Yeah, that's what I'm thinking - no matter how I try to tell myself that it will be fine, avoiding those cold starts will be key. I do plan on keeping this long-term; frankly, this is the best vehicle I've ever owned, and some days I enjoy driving it more than the 996. Hilarious given that I only paid $15,000 for it, and put a few thousand more and some time in it to take care of some deferred maintenance items.
