Ed, for those who do not know, how many miles do you have on your civic?
We read a lot of bad news on this sub forum, of course it IS the "mechanical problems" part.
So tell us the good news in some cases, like on yours? Aren't you pushing like 300,000 miles on the original engine/trans?
yep, I'm at 291,000 miles. I recently replaced the alternator and the door knob rod that opens the door fell out of its place b/c of a broken plastic part. Fix: $4. I religiously take care of my car and drive it conservatively. It also helps that that commute is mostly highway. YES, I dread the day I MIGHT see a crack on the block and notice a loss of coolant. So far I haven't. My mechanic friend told if it hasn't done so by now, it won't, especially at that mileage.
Original motor yes. I change the oil everytime the oil reminder goes to 15%. I average 6-8K miles between oil changes (all filters get changed regardless if they are not dirty). Original Tranny, yes. Regarding the tranny, I've changed the ATF every 30,000 (and again with the next 2 oil changes after that to get most of the old ATF out). Trannies can grenade themselves if the fluid isn't changed regularly. Should be done every 30,000 regardless of mileage.
In these 300,000 miles, I've:
1) replaced the front calipers (ok by me and this was several years ago)
2) replaced the A/C compressor (seems to be problematic at 100K or so). I got a new one on amazon for $300 last year.
3) replaced the passenger side motor mount. This was about 2 years ago.
4) replaced the alternator (two weeks ago)
5) replaced the pipe behind the muffler (It could've been the whole muffler with the pipe, I don't remember). This was last year.
6) replaced rear shocks. This was 3 years ago.
Good news? These cars WILL LAST if you take care of them. If not, well, whatever, that's on you, LOL. Other problem areas of the 8th gen is the paint. A lot of their clear coat seems to peel, but my Borrego Beige hasn't. I wash my car by hand about 5 times a year with Meguiar's shampoo (yellow liquid, it also waxes it) and nothing else. I SHOULD hand (or buffer) wax my car more often, but the paint is in great shape. When I do, I use cleaner wax. I know, my car deserves better, but I just don't have the time. Anyway, I can't think of anything else these cars suffer from.
The coolant/cracked block issue is hit and miss (IMO). It doesn't happen to ALL civics, but when it does, it sucks. Hard. If the car is in good shape (mechanically and esthetically), then I would venture on to say it is worth getting a new (2010+) block. It all depends if it's worth it to its respective owner.
Sorry for the long post.
