oil in IC/IC pipe

[Smitty]

I have recently replaced timing belt, water pump, head gasket, & had valves replaced that were bent. I have noticed oil in IC pipe just before the intake manifold. What causes this? Turbo oil seals? PCV valve? Etc?:zx11:

Turo oil seal,there will be always a certain amount of oil in the IC hoses,this is not unusal,and nothing to worry about if it is not exsesive.

we changed the PCV valve, & replaced the broken dip stick tube. this seems to have made the vehicle run much better. i read that a lack of possitive pressure on the boost causes oil leakage by the turbo oil seals. this apparently was the case. thanks for the reply.
