E46 M3 (S54) CPV High-Temperature O-Ring and Service Kit for Constant Pressure Valve
**FALL 2024 - THESE ARE IN STOCK!**
It doesn't look like M3Forum will be put back up, so I want to ensure these are available as people continue to service their cars. For those who may not know me, I'm the one who developed and have offered this CPV oil-leak fix/solution exclusively to M3Forum members since back in 2011! Viton Fluoroelastomer high-temperature O-Rings to fix the infamous CPV oil leak on the S54 motor (also known as the Euro valve). These rings are much higher quality than the Buna-N o-rings that are used for most gaskets (including the CPV). These have twice the temperature threshold (400 degrees) and are much more resistant to oil/petroleum products. If you notice an oil leak under the car where the engine and transmission meet that appears to be the rear main seal, its most likely a CPV leak. It isn't the actual valve that has failed, but the o-ring seal itself has hardened and failed. In fact, the CPV is not a common failure item, so replacement of the valve is not necessary. Exact fit to factory specs!
The o-ring on the CPV WILL leak, it is just a matter of when. Even if you are purchasing a new CPV, you should still replace the o-ring with this more durable one! The kit includes the special tool for CPV removal. A 4" extension is recommended. If performing this job with stock headers, a swivel tool will also assist in accessing the valve!
3 Ordering Options:
$5 for one o-ring
$8 for two o-rings
$25 for the kit, which includes the removal tool and (2) o-rings
