Over time, the seals inside Subaru’s AVCS pulleys can begin to leak, leading to oil seepage around the front of the cylinder heads, inconsistent cam timing performance, or AVCS system codes.
The Flatirons Tuning AVCS Cam Pulley Reseal Kit includes the critical O-rings and seals needed to properly reseal your OEM AVCS pulleys, restoring smooth and reliable operation without the high cost of complete pulley replacement.
Each kit uses OEM components designed to handle high-temperature engine oil environments and maintain a secure seal under performance use.
Ideal for any engine rebuild, cam service, or routine maintenance when the timing system is already accessible!
Includes:
- AVCS Cam Cover O-Ring (x2)
- AVCS Cam Covers (x2)
- AVCS Cam Cover Bolts (x6)
