From the legendary EJ-series turbo platforms to modern FB direct-injected engines, we diagnose and rebuild Subaru boxer engines with the patience and parts they deserve. Most of what we see — oil consumption, rough idle, persistent misfires, weeping seals — has a known fix when you know Subarus.
What we work on
Every Subaru boxer four. We carry the special tools, OE gaskets, and torque specs that make the difference between a one-time repair and a comeback.
- EJ20, EJ22, EJ25 (SOHC and DOHC)
- FA20, FA24 direct injection
- FB20, FB25 PZEV and standard
- Turbocharged WRX and STI builds
Common Subaru engine issues we fix
If your Subaru is drinking oil, leaking onto the driveway, or running rough, you are not alone — and these are repairable.
- Excessive oil consumption (piston ring service)
- Cam carrier and cam seal leaks
- Misfires from valve cover gasket oil contamination
- Timing chain tensioner failure
- PCV and crankcase ventilation issues
Our process
We start with a documented diagnosis — compression, leak-down, fuel trim, and scan data — before we recommend a repair. You see what we see, and you get a clear written estimate before we touch a tool.
