Alfa 156 2.0 CF2 Cam Specs - Technical
I am looking for a technical answer on the specs of the standard cams contained in this engine.
I have a 99 model and I am doing research using pressure transducer and a scope to verify the cam timing is O.K. or not, on a running engine, to aid diagnostics. It is a quick (5 min) test to verify engine breathing by placing said transducer into intake and then exhaust gas flow. Mapping the resulting pressure pulses vs crank rotation provides confirmation of engine breathing.
In order to get good basline data I need to know the specs of the standard cam.
I am looking for:
Cam Lift IN: Cam Lift EX: Duration: Lobe Center Angles: Valve Timing: Valve lift: TDC Clearance.
I also need to know the degrees of advance of the inlet cam once the variator solenoid is activated it may be actuated in stages, if so this advance 'curve' would be helpful.
I intend to share my results here when I have completed the research.
many thanks in advance
