Absolute Reseal (Cam Carrier & O-Ring Specialist)
Stopping the Leaks at the Source
The Modern Subaru Challenge: FB & FA Engine Leaks
While older Subarus were known for head gasket failures, the modern FB and FA engines (2012–Present) face a different challenge: failing cam carrier sealing and internal O-rings that are prone to failure.
The “Chocolate Milk” Problem
Modern FB/FA engines feature a unique upper oil pan design. Inside, small rubber O-rings separate your oil from your coolant. Over time, these O-rings smash flat or crack due to heat.
The Result: Oil leaks into your coolant, turning it into a “chocolate milk” sludge that leads to deterioration of all the coolant hoses which results in your engine overheating and catastrophic failure. Our Absolute Reseal replaces these critical O-rings at the source, saving you from a costly engine replacement later.
Don’t Settle for a Patch Job
When these O-rings fail, they cause dangerous oil-to-coolant contamination or drip onto critical points of the engine harness or the exhaust, creating a constant burning oil smell. At Absolute Subies, we specialize in the Absolute Reseal Package—a true engine-out service designed to address every leak at the source and return your Subaru to factory-dry specifications.

Why a Complete Reseal is Required
A proper Subaru reseal cannot be done with the engine in the car. We pull the motor entirely so we can access every hidden O-ring and clean the old sealant down to the bare metal. We don’t do quick external patches, we rebuild your engine’s sealing system for long-term reliability.
