Precision Cylinder Head Specialists

AWD Machine, a division of All Wheel Drive Auto, and located in Bothell, provides precision machining for modern aluminum cylinder heads.

We handle resurfacing, multi-angle valve seat machining, valve regrinding, guide and seat replacement, and thread repair, along with full cleaning and prep. The process is straightforward—inspect, machine, verify—so the cylinder head goes back on the engine sealing correctly and operating as expected.

Built on real-world repair experience and using equipment from Rottler Manufacturing, AWD Machine delivers consistent results for repair shops, builders, and DIY customers.

We run a full-service schedule Monday through Friday with fast turnaround times to keep jobs moving without delays. Heads are processed continuously through the week rather than batched, which allows work to move from cleaning to machining to final check without sitting.

Scheduling is straightforward, communication is direct, and turnaround is set based on the actual work required so you can plan the next step without guessing.
