Engine Mechanical problem
1992 Other BMW Models 6 cyl Two Wheel Drive Manual

ive got a 1992 5 series 2.0l its a m50 24 vavle DOHC engine and im having trouble timing up. On the 2 smaller spockets that join the 2 cam shafts together there is 2 arrows on each one and on the bigger sprocket that joins the cam shaft to the drive shaft also has arrows on it can you just tell me where the arrows should be when the engine is at TDC on its compression stroke?
