E46: Brakes + oil leak sorted - still running rough!

Wednesday 16/7/14:

Replaced vacuum-pump.
Replaced both camshaft-sensors.
Replaced MAF sensor.

Well, I'm certainly glad to report that the oil gushing onto the exhaust / cat has stopped with the replacement of the blown up vac-pump and I now have good pedal feel and stoppage. Sadly, even the return of some vacuum isn't enough to cure the low-idle and rough running. I replaced the obvious things, both cam sensors and the mass-airflow meter, but this hasn't sorted it either. I'm guessing there is either a severe vacuum / vent problem, or it's going to be to g related... Oh joy!

The diagnosis will go as follows:

Remove and fully check out inlet manifold.
Thoroughly check all CCV lines and the valve.
Clean and check all electrical connections.
Test for compression.
Move on to timing.

Other jobs:

Adjust handbrake and refit discs.
Fibreglass fill n/s/r wheel arch.
Check squeaky ABS sensor.
