I made this thread so I wouldn't completely hijack the persons thread where this started.
Most people with VWs know that there have been specific complaints about the 1.8T engines. Main complaints were from Passat owners, so I ended up taking some pictures from my car, which uses the same engine but just in a different configuration (transverse vs. straight).
My breather hose, which is a part of the PCV system, which often times gets sludged up on these engines, cracked and I figuered I will take pictures of how it looked inside.
Here is the location of the hose, Y pipe, and you can obviously see the crack.
After I replaced the pipe I cracked it open to see if there were any deposits inside and how it looked.
Here is what I found:
It was eaten up byu the hot oil fumes, heat and cold shifts I would say. The rubber became very brittle and resembled dried, cracked river beds or deserts.
I found oil throughout the system and it all wiped off without a problem.
JAG asked about the following things, so I am putting that up as well.
OCI: Mostly 5000 miles. I have gone as long as 7500
Oil used: Mobil 1 0w-40, Synpower 5w-40, Syntec 0w-30.
* The interesting part about this was that the car did not start receiving synthetic until 23 000 miles. At that time the OCI was 3000 miles.
Driving habits: Mostly highway, but the car sees every type of driving. Redline; slow driving with early upshifts; stop and go and highway.
*Again this is a special category, because when I lived in NYC the car was mostly stop and go (while on conventional oil).
If anybody has any other questions let me know.
