Not long ago it was propelling our Subaru Impreza WRX around in the dirt and powering it into some donuts; now it’s sitting on the workbench in several pieces.
Thankfully, that was deliberate, as Redline Rebuild host Davin has stripped the WRX’s flat-four engine to its component parts and begun to clean off years of gunk.
To everyone’s surprise, the engine really doesn’t seem that bad either. No doubt it needs a closer look, and Davin is already making a shopping list of which parts need changing, what can be reused, and what should be upgraded, but it’s amazing how well the engine – well, one half of the crankcase – has come up after a thorough clean.
While generally stout, these Subaru engines do have some common weak points, so a proper inspection will be required to ensure everything going back in for the rebuild will be up to the task.
But that’s part and parcel of any work like this – whether the recent Mini A-series rebuild project, or the usual pushrod V8s that go through the Hagerty shop.
Along the way, Davin is enlisting the expertise of some Subaru specialists – in addition, naturally, to the advice doled out in the YouTube comments – and we’re sure to hear more useful nuggets as the build progresses.
