Cylinder Heads Perth
Precision Repairs, Reliable Power
Cylinder heads play a critical role in your engine’s performance. From valve sealing to combustion efficiency, a properly functioning head ensures your 4WD performs as it should — especially under stress.
At Oceans Automotive, we handle cracked, warped, or leaking cylinder heads. We machine, pressure test, reseal and reassemble using OEM-quality parts and the right tools for the job. Whether petrol or diesel, we’ve got the experience to restore your engine’s top end with confidence.
The Process
Cylinder head servicing is a precise and multi-stage process that requires careful handling and expert assessment. Here’s how we get it right at Oceans Automotive:
Initial Diagnosis & Inspection
We start by confirming the symptoms — overheating, oil contamination, white smoke or loss of compression. A visual inspection, compression test and cooling system pressure test help us determine whether the issue lies with the head, gasket, or a deeper engine fault.
Removal of Cylinder Head Assembly
Once confirmed, we remove the cylinder head from the engine. This includes draining fluids, disconnecting intake and exhaust components, and carefully disassembling surrounding parts to avoid damage.
Crack Testing & Warpage Measurement
With the head removed, we perform detailed testing — including dye penetrant testing for cracks, pressure testing for hidden faults, and straight-edge/mechanical checks for warpage that can lead to sealing failure.
Machining, Sealing & Valve Work
If the head is repairable, we clean, machine and resurface the mating surface, reseat or replace valves, and install new stem seals. The result is a flat, clean, properly sealing head that’s ready for reassembly.
Reassembly with Quality Parts
We fit a new head gasket, torque the head to spec in sequence, and reinstall all related components — including camshafts, timing gear, and associated seals. We also replace any worn hoses, bolts or gaskets in the process.
Engine Testing & Road Test
Once the engine is reassembled, we refill fluids and start it up, monitoring for leaks, idle stability, and operating temperature. A road test follows, ensuring the job has been done right under real driving conditions.
