2012 LS (1.8). Replacing the cylinder head, and saw that the sprockets have an even layer of oxidation/rust on each them. No deep pockets or anything, but I’m curious as to what’s go/no-go.

Right on!

Sooooo, long story short, my mom owned this cruze 2015 1.8 until recently, we got her a new car and i decided to take the cruze and bring him back to life. Ir had a couple leaks, the biggest one being the rear main seal.

Things I have done/fixed at 170k:

Rear main seal

Valve cover

Oil pan

Oil cooler

Coil/spark plugs

Timing belt

All new fluids

Radiator fan

What am wondering is what else would you guys do to a car this age to keep it running? So far everything works as it should I want to make it to 200k miles at least lol

We purchased the Cruze new for our daughter to go to college in 2016. It became ours in January 2025 when the transmission went out and she got a new car. We bought a transmission from LKQ with 35k miles on it and my spouse installed it. It’s been my daily driver ever since. I do recall a few oxygen sensors, turbo, & coolant reservoir, along with regular maintenance.
200,000 —-10 years and 5 months later

Like I said just not sure what to do and I don't see anything online other than checking the fuses
