what is the correct oil pressure ? + strange pipe

[johnnys]

I have just got a new engine in my 2002 c4 996.

This was after 4 RMS leaks.

I thought the engine pressure didn't look right and just before checked my manual and it says it should be running at 3.5 bar at 5000 rev with a warm engine.

well it hits 5 bar at 2500 rev

Iv only done 900 km so far so I hope this isnt effecting the engine as I wish to run it in well.

Also there is a rubber hose coming out from the left of the air intake that has a metal plug in it. Nothing for it arrived with the engine and the service guys said they asked Porsche and they said dont worry about it. How ever on the new 2004 996 there is something attached to it. My dealer does not have a car in so I cant see what it is anyone know what that sounds like ?

They had to use my old air intake and Im worried that It was assumed the part that fits onto this pipe was meant to be there as well and It needs to be ordered.

the engine they put in is not the same as the one they took out so It must be a new version.

This sort of job is not done in Wellington NZ as the population doesnt support high Porche ownership and the cars that are owned arent drivent much my car had 46,000km on it when the engine was done. Any ideas ie the difference between a 2002 engine(3.6) and a 2004 model??
