It is highly possible to still get oil in the intake tract, even if you eliminate the possibility for it to enter the intake stream through the PCV. The same blow by that may be pushing oil out the PCV hose will also push oil through the turbo compressor "seal."mr20nza said:After trying this for a few months, there seems to be no difference between recirculating the PCV pipe or venting it to the atmosphere (K&N breather filter sustained at a height above the valve cover). Today I checked the IC pipe from the IC--->TB. When I added the K&N breather filter and vented the EGR pipe, I cleaned out the IC pipes very well, not a bit of oil remained.
The oil remains after removing the IC pipe from the IC-->TB look identical compared to when I removed it before I was venting the PCV. Therefore... I see no reason why this modification is beneficial if it doesn't hold back oil from entering the intake and piping... either that, or I simply have leaky turbo seals. But either way, I saw no difference in oil build up, it simply remained the same.
