   Why does my Subaru WRX have a turbo problem?

   • That said, a lot of older Subaru WRX’s may have already had the turbo replaced. Otherwise, turbo problems become more common when tuning and modifying the WRX and WRX STI models.

   Why does my Subaru WRX misfire?

   • Leaking or faulty injectors may also cause misfires. Finally, newer direct injection (DI) Subaru engines can have misfires due to excess carbon build-up. Carbon build-up usually isn’t a problem on the WRX until close to 100,000 miles. It’s standard maintenance on DI engines since there isn’t any fuel flowing over intake valves to clean them.

   Nov 21, 2023 · The primary culprit is a faulty camshaft seal that is prone to early wear and tear. When the camshaft seal starts to leak, the camshaft gets less oil, which causes more friction and heat. You could check the engine for signs of oil leaking onto it from the faulty camshaft oil seal.
