Do you own a 2.0T TSI powered VW or Audi? Do you have a engine stumble or misfire, check engine light or mysterious oil leaks in the driveway? Theres a good chance your rear main seal and PCV valve is failing. Don’t replace it with another known failure part from the dealer. We have an upgraded solution to permanently fix that seal. Along with the PCV valve that causes that rear seal to fail you wont have to worry about this issue again!
The factory stamped factory unit uses a flimsy and very thin rubber surface to seal around the crank and even when holding a new one in your hand, you wonder why the manufacturer would think this would be reliable long term. Our replacement solution uses a Patented billet machined plate that is bored to a larger diameter to make clearance for use of a Viton rubber seal that is more heat, fluid resistant, and more than double in thickness. In other words it makes you feel a whole lot more confident when installing the new part when removing the old. The crank is constantly spinning inside this seal too so over time as heat cycles are put through the engine, rubber will expand and contract and become brittle over time, especially when saturated with oil constantly.
The most common causes of rear main seal failure is failure of the PCV valve. The TSI engine is known to have PCV valve failures, which will cause an excess of crank case pressure. This pressure will cause more pressure than the rear main seal can handle. PCV issues can surface with multiple symptoms but when a car doesn’t show signs of many of them we end up pressure testing the system to make sure the rear main seal wasn’t compromised. It is safe to say that if a car needs a rear main seal it needs a PCV valve in most cases.
This Job is expensive due to having to remove the transmission to access the seal.

Porsche Boxster IMS installation at the shop today. IMS *bearing* failures are a real problem. The bearing that supports the intermediate shaft was poorly designed and prone to failure. It gives little to no warning before it fails and when it does fail it destroys your motor. Dead, done – you’re not rebuilding the old motor because it’s fu^%ed. You’re buying a new motor.
This has been discussed to death on line, and then discussed a zillion times more. In the end though, the answer is always the same, only Porsche knows, and they probably don’t even know, and at any rate they are *not* saying anything.
Problem is that Porsche replaced a lot of engines in the first five years or so, all under warranty. Not all of them were IMS issues, some were RMS issues that could not be solved, some were for cracked heads, some were for porous castings, some were just service manager’s taking the easy route to making a customer happy. Porsche took all of the motors back for analysis. most were re-manufactured with upgrades and these went back into the system.
These days we rely on the experience of knowledgeable independent repair people, but they only see cars with problems so they have a biased view.
