Review on 🔧 New Genuine GM 55573746 Camshaft Cover - Improved Replacement: Part 25198874 by Ayush Bonuccelli

Great factory part for a great part. The sad thing is when others have replaced this part because the pressure control valve on top of the cap has failed (a whistle along with a rough idle), like mine you need to fix the root of the problem or you will replace these cover again. The problem is the failure of the small orange PCV rubber valve in the intake manifold. What you need to do is remove the hard corrugated/ribbed line that connects to the top of the intake manifold and shine a flashlight through the hole on the intake. You should see an orange PCV valve. You may need to spray in some carburetor cleaner if the valve is covered with oil. If you don't see it after that, this will lead to the failure of the pressure control valve. Mine is gone and this is the second time I've changed the cap. You have 2 options. 1) Replace the intake manifold and worry about the PCV valve eventually failing again, which is guaranteed to happen due to poor design, or 2) google "Chevy Cruze 1.4L Turbocharged PCV Valve Repair Kit", buy and install it, which is pretty easy. It took me about 3.5 hours to complete. With this kit you can bypass the crappy factory design of the PCV valve and most likely never have to replace a cap again. You can also search YouTube for it and there you will find a video that explains this question much better. How does it help some.
