hi i bought the car with the m50 mani already on, but the pcv pipes were terrible. the pipe going back to the intake was reduced down to a vacuum sided pipe, and where it connects onto the pcv the pipe was bait too small and has split swell

. i have welded the pipe on the dipstick and i have just purchased the e34 525i intake boot. my question is what size are the pipes and elbows i need? it would speed me up ordering them now and less time on waiting for parts to arrive
second is the propshaft bearing i have the zf box and i am using the e36 prop and need the e30 centre bearing. i bought one off ebay fitted it and it is slightly different and the rubber has come away from the bearing already and its not even on the car yet

does anyone know where i can get a decent centre bearing from but not break the bank?
the brown e30 temp sensor is in,does the wiring go to the c101 plug? both wires or just one?
cheers
jon
