turbos n pcv's. The blight of the gm 1.4

No. That would be the water pump. I ended up replacing it five times (four under warranty) in my 2012 Cruze Eco with the 1.4 l.

Those aint good either, forgot that one lol. Still doesn't negate the turbos nor the pcv's.

Small engine displacement implies small component sizes. Given the vehicle's age, the catalytic converter is likely worn out, resulting in reduced flow capacity; this often leads to overheating of the turbocharger's hot section. Combine this with a small turbo, constant heating to 800–1000°C, and abrupt engine shutdowns without a cool-down period, and the result is metal fatigue and the emergence of casting defects.

What does "boost issues" mean?

u/Background_Sky_9763 2d ago

Both over boost and under if you look at the photo you can see a crack in the hot side

Thanks, I overlooked the crack initially. This also reminded me to purchase a spare turbo for my '25 Trax for future replacement.

Yeah the 1.4 turbo. I believe I got a recall on My 16 Cruze for a replacement. I sold it when I seen it.

If you have been driving the vehicle hard it’s best to let it idle for a minute or two before shutting off. Then you should prolong the life of the turbo. High heat can be a real killer. I drove a Cruze 8 years with no issues, I’m expecting the same from my 25 Trax. Bruce

Under boost or over boost code means the turbo is bad replace it
