Saab 9-5 needs help

Hello, I bought a 2001s Saab 9-5 combo with 185 hp and automatic transmission. Is a Swiss model. 205,000 km of complete maintenance at Saab all about 15,000 km. It is not yet installed the new crankcase ventilation. Unfortunately the ZKD is also over. Otherwise everything in it except sunroof, CD changer and theft warning system. Now to my questions: can I install the oil tank seal also with a seal made of 0.3 mm sealing paper? (I have my problems with sealant) Pressure tube just before the entrance a throttle valve housing I have a connection for a pipe, similar to the connection to the vacuum pume at the cylinder head. Where does the pipe come from where do I have to look? I found nothing at first glance. Does the automatic transmission from the 3.0t V6? LG Karsten
