It's more of an issue with aircraft engines where an overhaul can start at $25,000 and go up, and where it's quite likely that an engine has been sitting for too long. That having been said, I did see one airplane that had been sitting for 15-20 years be started and flown out on a "ferry permit" for it's annual inspection at an airport 150 miles away.

Unless the cam is sitting in the oil, I don't think the engine design makes much difference. There is a lot of pressure on the cam from the followers - when the rust comes off it leaves pits with possible sharp edges. These will spall the followers and the cam in time. How much time depends on how deep the rust was. YMMV.

Yes - "Camguard" - but you have to use it before the engine sits for a long time. I use it in our cars because we only drive them every other week or so. I also use it in the airplane because I never know when it might be down for more than a couple of weeks.

Starting a car that has been sitting and having its engine being "OK" are two different things. One of the big killers is rust on the cam from the oil having drained off. The rust grinds the cam followers shedding metal into the engine. Yes, it's running, but for how long before it self-destructs?

One of my least favorite colors, personally. Though I might have forgiven it if it had a manual transmission.
