I have an 06 STi, which I have recently lost ALL oil pressure in. I took the car apart, replaced the oil pump, put it back together, and still have no oil pressure. I also removed screens from the oil lines connecting to the turbo, so that can't be the issue. My next step is the oil pickup tube. My question is this: Is the pickup tube actually called and "oil strainer?" And if so, I have heard multiple things about this part actually being welded to the block. However, I have looked at several diagrams, and they show it just being bolted on. Anyone out there know the answer to this? Also, how hard of a job would it be for me to do myself? I know the engine has to be lifted, I would just like to know if any of you guys have done this yourselves? Thanks in advance for the help guys.
