250K isn't a stretch at all IMO.... unless the car is tracked quite often.1. There isn't proof out there about a trend of carbon build up problems in Honda DI engines.
2. The easiest way to avoid problems with a warranty claim is to not install aftermarket parts like a catch can. If that worries you, don't bother during the warranty period.
3. 1st engine change?
Here is your answer from a valid source.
4. 250K miles on these engine?
There isn't enough data out there to know that yet.
The K20C engine came out on FK2 CTR (europe), not enough years in the road to know their longterm reliability but so far the engine seems to be pretty good.
I owned an Acura RSX typeS with the K20 family of engines and sold it at 216K just because after 14 years I was ready for something else. That engine ran amazingly well and have no doubt that it go another 84K or more. It started running it's best at around 100K miles. I remember thinking 'well, it is finally fully broken in'. I didn't run it that hard or flog it every chance I got as most of the time I was just going to work and back, but in general, Japanese engines, especially Honda and Toyotas are good for at least 300K or more. Yeah, I know we're talking a turbo engine now that will probably get flogged to death and this is more about general usage.
So to wrap it up; my buddy in CA has a 02 Toyota Tacoma with the 2.7L engine and he is at 730,000 miles. Yeah, he had to have a valve job, transmission rebuilt, ball joints but the point is, the truck still has the factory short block untouched! Pretty amazing if you ask me.
Your car if raced every weekend results may vary.
