Have you all inspected your valves because DI?

I’m at 211,000 miles on my 09 LNF. Lots of minor things broke over the years, but this thing feels unbreakabke.
Power steering motor 3 times, twice under recall, third time I did it myself.
Driver door handle has broken 4 times.
Original factory alternator just went at 210K
Original factory battery went at 170k
Starter went at 140k
Shocks and struts twice, around 80k each time
Original factory radiator blew up at 200k during an ice storm
Replaced both cam actuators when they threw a CEL at 200k
Evap purge solenoid line had to be replaced because it was rubbing against the break fluid reservoir and got a hole in it.
Cam position sensor changed at 210k
Nipple on intake tube connecting PCV line busted around 200k
Several sets of leaky headlights
ignition lock cylinder seized up and replaced under recall
By far spent the most money on brakes, rotors and tires. It ate them like crazy.
As of right now the clockspring is broken so there’s no horn, air bags, of DIC controls.
everything else on the car is original and bone stock, including the clutch. Was driving It between 50-120 miles a day since I got it in 2010. Got a new Chevy Cruze last July and now I drive it mostly for fun. It feels like a tank compared to the Cruze.

At 170k I had to patch a section of rear quarter and rocker panel that rusted out bad. Had to cut out a 9" x 12" section from a car at a yard to fill in. Check your rockers guys. A hole/body plug in the door sill and pillar and some Fluid Film would have saved me a ton of work had I adressed it a few years ago.

I did check valves at 113k. Installed the powell v3 oil separator, ran it for 15k till an injector failed and I swapped in an LDK (timing was due, I thought cyl 4 was gone, I needed it done quick). So I disassembled the old engine and the valves looked no worse than when I did the cleaning at 113k. I can't recommend the separator, but I can recommend giving them a clean every now and then. I probably won't have to clean these for about 40k miles. If I feel like doing it then. If your car is winter driven check the fuel line!! I'm about 90% sure a piece of rust made it through the fuel system to the injector and held it open.

Hey long time member but havent been around in 4 years.
2010 cobalt sstc owner. Bought new for $30,000, drove it for 8, gave it away to friend at 286,000km when the engine started to have issues. Piston ringland #1 started to chunk away. New owner is a GM mechanic and pulled it apart and put a few grand back in to rebuild it for a daily driver. I moved onto a 2018 STI for a reliable DD.
The car was a blast to drive and own. Mostly small issues over it's life, replaced under warranty. GMS1 until warranty was up, after 23psi 91 octane Trifecta ECP tune with a k&n intake, zzp 200cell downpipe and forge atmospheric blow off. It was quiet exhaust wise with a rumble when you stepped on it and a massive blow off. It snapped necks daily and was a bit rice but my fav mod ever by far. Never dynod it but i just told peeps it was low 300's hp mid 300's tq.
Pretty low cost of ownership. Had to pay for new headlights(water inside) wheel bearings(2) roll pin in the shift assembly, Corroded abs module wire, control arm bushings, all 4 rotors/pads replaced twice, zzp big brake kit the second time. $1000 for the intake,downpipe,tune,bov. Great bang for he buck overall. 27-33mpg depending how driven. Tire life wasn't that good either, but I was in my 20's and loved to WOT. The LSD was awesome. Oh and that damn $150 trifecta cable...
The 2.0 Ecotec always felt strong, unlike the 2.5 EJ in the STI, I have a bit over 100,000km on the STI and it's a beast in the winter, but not as fun as the cobalt was in the summer, that torque steer was insane with a 110kmh 2nd gear. I NLS'd a few dozen times and it felt good to not lose boost. The STI is an 80kmh 2nd gear and loses a ton of boost. And there's a 500lb difference.
I think that the pistons went due to the Trifecta ECP tune/bov.Think it would've lasted longer staying on GMS1. Never de-coked the engine either, did seafoam once(half in breather hose, half in tank), ran 93/94 rarely.
Cheers. Don't sell your baby unless you have too lol.
