This is one of several documented WRX / STI problems we track, and it fits inside the broader Engine Guides guide. If you're weighing repair against replacement, cross-check the Subaru repair-cost database and any open NHTSA recalls on your VIN before booking a shop.
Subaru applied too much RTV sealant at the timing-cover and oil-pan joints during assembly. Chunks break free over time and lodge in the oil pickup screen, starving the bearings.
Manufacturing defect — over-application of RTV at engine assembly.
Manufacturing defect — over-application of RTV at engine assembly.
National average $2,200–$4,000. Pan drop + cleanup; $8-12k if bearings already damaged
Difficulty 4/5. Drop oil pan, scrape RTV, reseal with Subaru OEM gasket maker, inspect bearings
Low oil pressure warning despite full oil; Silicone bits visible on dipstick; Glitter (bearing material) in oil at change
