Toyota Prius Cylinder Head Replacement | Engine Repair Broken Arrow
When a Toyota Prius starts misfiring, losing coolant, or running rough, it may be more than just a head gasket issue.
In some cases, like the one we show in this video, a full cylinder head replacement is necessary. This Prius had suffered damage likely caused by overheating or valve failure, and we had to tear down the engine for a complete top-end rebuild.
If your Prius is showing similar symptoms, don’t wait. Delaying repairs on a hybrid can lead to more costly damage. Visit a trusted mechanic near me in Broken Arrow who understands both hybrid and traditional engine repairs.

What Causes Cylinder Head Failure on a Prius?
Common causes include:
Overheating from a failed water pump or clogged radiator
Oil starvation due to PCV or oil control issues
Valve or timing component failure
Once the head is cracked or warped, it’s no longer safe to reuse. At that point, replacement is the only reliable option.
What to Replace Alongside the Cylinder Head
When performing a cylinder head replacement, we always recommend additional repairs while the engine is already disassembled. This saves labor costs and prevents future breakdowns. Here are the related services we often include:
Head Gasket Replacement: A critical part of the job. We always use high-quality MLS gaskets.
PCV Valve Replacement: Cheap insurance against future oil leaks and crankcase pressure issues.
EGR System Cleaning: Gen 3 Prius models suffer from EGR clogging. We clean or replace it during head jobs.
