Valve Cover Replacement on 2011–2015 Chevrolet Cruze and 2016 Cruze Limited — 1.4L Turbo
A valve cover contains engine oil at the top of the cylinder head and incorporates part of the crankcase ventilation system on the Chevrolet Cruze 1.4L turbo. For a 2011–2015 Cruze or 2016 Cruze Limited with the appropriate LUJ/LUV engine, oil leakage, a burning-oil smell, whistling or rough idle can lead to inspection of this assembly. P0171 can accompany a ventilation fault, but neither that code nor any other code proves that the cover must be replaced.
This guide covers planning and diagnosis for the first-generation 1.4L turbo installation using the selected aluminum replacement. It is separate from the 1.8L Cruze cover. Confirm the engine code and VIN before ordering: a broad listing that includes the year 2016 does not establish compatibility with the redesigned second-generation Cruze.
Intermediate; diagnosis can require professional test equipment
Plan 2–4 hours for a careful first-time cover repair, plus diagnosis
Planning allowance: $80–$170 for a cover kit; tools and other repairs extra
Allow the engine and turbocharger area to cool. Park securely on level ground, keep the key away and follow the vehicle’s battery-disconnection instructions. Do not reach near belts or fans during running tests. A flashing malfunction light, severe misfire, oil-pressure warning or oil dripping onto hot exhaust parts calls for stopping the engine and addressing the fault before driving.
Vehicle and engine fitment
| Vehicle | Catalog years | Engine and scope check |
|---|---|---|
| Chevrolet Cruze | 2011–2015 | First-generation 1.4L turbo; confirm LUJ/LUV and the original cover layout. |
| Chevrolet Cruze Limited | 2016 | Carryover first-generation 1.4L turbo only. |
| Chevrolet Sonic | 2012–2020 | Selected 1.4L turbo applications; not the Sonic 1.8L. |
| Chevrolet Trax | 2013–2021 | Selected 1.4L turbo applications with market and engine-code restrictions; use Trax-specific repair instructions. |
| Buick Encore | 2013–2021 | Confirm the listed LUJ/LUV application. Other 1.4L variants and Encore GX must not be assumed compatible. |
| Chevrolet Volt / Cadillac ELR | Volt 2011–2015; ELR 2014–2016 | Listed separately in the manufacturer’s catalog. These hybrid applications need independent VIN and engine verification; this turbo Cruze procedure does not apply to them. |
Use the catalog table as a screening aid, then check the exact engine and part references. Inspect the breather outlet, coil opening, oil-fill neck, dipstick location, gasket profile and harness mounting points. A year-and-model selector that overlooks engine differences is not enough to justify installation.
Selected aluminum cover and included parts
ASIN B0DKTKLMH6 identifies A-Premium APEVC0216, a silver aluminum cover. Amazon lists the gasket, bolts and oil filler cap, and specifically requires the bolt sealing rings to be used. Reference numbers include 55573746, 25198877, 25198498 and 25198874. Compare the received kit with its instructions and the original assembly before removing anything.
The aluminum material is not a promise of more power or a permanent cure for ventilation trouble. Inspect the gasket channel, bolt seals and machined contact surfaces for damage. Do not substitute ordinary washers for the supplied sealing rings, and do not mix old and new hardware unless the kit instructions explicitly allow it.

Diagnose the PCV system before buying a cover
GM bulletin PIP5197 describes how a missing or displaced intake-manifold nonreturn valve can damage the cover’s ventilation diaphragm on specified LUJ/LUV applications. It calls for checking both assemblies, along with intake leaks and oil-cap or dipstick sealing. That relationship matters when a new cover fails again: replacing the cover alone may leave the underlying problem in place.
| Observation | Useful next step | What it does not establish |
|---|---|---|
| Oil along the cover seam | Clean the exterior and trace the first fresh wet point. | Oil farther down the engine does not identify its source. |
| Oil in the plug wells | Inspect the well seals and coil boots; remove pooled oil before opening a plug hole. | A coil does not automatically need replacement merely because it is wet. |
| Whistle or unstable idle | Inspect ventilation hoses and have the PCV system tested using the applicable service procedure. | A whistle alone does not identify which component has failed. |
| P0171 or other airflow/fuel-trim codes | Record freeze-frame data and diagnose air leaks, ventilation operation and the intake nonreturn valve. | Codes are not proof that this kit will solve the fault. |
| Repeat cover or seal failure | Check crankcase pressure and the related intake components. | Installing a metal cover does not remove the need for system diagnosis. |
GM’s bulletin also lists P0106, P0299, P0507, P1101 and P2096 among possible accompanying codes in its covered vehicles. Each has other possible causes. Do not buy a turbocharger, intake manifold or valve cover based on the code list alone. Use the current diagnostic information applicable to the actual VIN.
Photograph the leak before cleaning it and note whether it occurs at idle, after a drive or only after an oil change. That record helps separate a new leak from leftover oil. If the engine consumes oil without an obvious external leak, further testing is needed rather than assuming the gasket explains all of the missing oil.

Costs and preparation
Allow approximately $15–$50 for consumables beyond the cover, with reusable tools potentially adding $80–$200 if you are starting from scratch. These are planning allowances, not current Amazon prices or a shop quote. Diagnosis, a damaged breather pipe, an intake-manifold repair and ignition work can change the total substantially.
Ask a shop to explain which test supports each proposed replacement. A written estimate should distinguish the cover itself from diagnostic labor and any related fault. If the vehicle has already received multiple covers, that history is useful evidence and should be mentioned before another part is ordered.
Replacement workflow and specification checks
1. Record the connections and prepare the work area
Photograph the wiring and hose routes, gather the applicable service diagram and inspect the new kit on a clean bench. Keep small parts organized by location. Read the sealant’s application and waiting-time instructions before exposing the engine so you are not searching for supplies halfway through assembly.
2. Create access without damaging connectors
The factory procedure removes the coil, disconnects the ventilation pipe, moves the engine harness and removes the dipstick before releasing the cover’s 15 fasteners. Label connectors as they are disconnected. Support the harness rather than letting it hang from a remaining wire. Lift the coil evenly with the specified equipment and release hose locks without twisting aged plastic.
3. Lift the cover and inspect the sealing area
Account for all fasteners and attachments before lifting. Keep dirt and loose seals out of the cylinder head. Inspect the removed gasket and cover for evidence of the leak, then clean the mating surface gently. Avoid abrasive discs, metal gouges and excess solvent entering the engine. Remove every temporary opening protector before fitting the replacement.
4. Prepare the gasket and bolt seals
Seat the new gasket in its channel and retain all supplied bolt sealing rings. The factory procedure calls for sealing compound at two specified junctions, not around the entire perimeter. Use the exact location diagram and approved compound for the application. Do not borrow the special thread-sealant instruction from the different 1.8L cover.
5. Apply the correct tightening procedure
The GM 1.4L reference specifies 8 N·m (71 in-lb) for the 15 cover bolts in its illustrated sequence. The coil’s two bolts are also listed at 8 N·m. Confirm the aluminum kit’s instructions for its hardware and seals, and have the applicable sequence diagram available before assembly. Do not invent a bolt order from a photograph or use 71 ft-lb.
6. Reconnect and verify the result
Restore the harness routing, coil connection, ventilation pipe and dipstick. Check that all locks engage and no wire is pinched under a cover edge. Verify the oil level and restore the battery connection according to the vehicle procedure. Observe any required sealant waiting time before starting.
Run the engine only after the assembly is complete. Watch for fresh oil, an abnormal whistle and unstable idle while keeping clear of moving parts. Shut down if a problem appears. Recheck after a short drive and full cool-down, and confirm that the original diagnostic complaint has actually been resolved. Extra bolt torque is not a substitute for finding a leak.
For a visual overview, see 1A Auto’s 2011–2015 Cruze valve-cover demonstration. Confirm the demonstrated engine and replacement design before using any step; the selected aluminum kit may have different hardware.
Mistakes that cause repeat work
- Skipping the intake-manifold and PCV diagnosis when the original complaint includes a whistle or lean condition.
- Ordering for a second-generation Cruze based only on a 2016 year match.
- Losing a bolt sealing ring or substituting an ordinary washer.
- Coating the entire gasket with RTV or using the 1.8L thread-sealant instructions.
- Overtightening small bolts to compensate for a displaced gasket.
- Clearing codes before saving the information needed to diagnose the original problem.
Frequently asked questions
Does aluminum permanently solve the PCV problem?
No material choice can guarantee that. The ventilation assembly, hoses and related intake components still have to function correctly. Select a cover for verified fit and a supported installation procedure, then repair any confirmed cause outside the cover.
Should I replace the intake manifold at the same time?
Only when inspection and the applicable diagnostic procedure show it is needed. GM’s guidance explains why it must be checked; it does not mean that every cover replacement requires a new manifold.
Can I use this procedure on a Volt or ELR?
No. A catalog listing for the cover does not make the turbo Cruze workflow appropriate for a hybrid vehicle. Confirm those applications separately and use the vehicle’s hybrid service and disabling procedures.
Do I need new spark plugs and a coil?
Not automatically. Inspect for oil contamination, damaged boots and other evidence, then follow the maintenance schedule and diagnostic results. Replacing unrelated parts by default adds cost without establishing the cause.
