CHECK CURRENT DATA. 1) Starttheengineandletitidle. 2) MeasuretheAVCSsystemoperatingangle and oil flow control solenoid valve duty output using Subaru Select Monitor or general scan tool. NOTE: • SubaruSelectMonitor For detailed operation procedure, refer to the “READ CURRENT DATA SHOWN ON DIS- PLAY FOR ENGINE”. <Ref. to EN(H6DO)(diag)-26, Subaru Select Monitor.> • Generalscantool For detailed operation procedure, refer to the general scan tool instruction manual.	Is the AVCS system operating angle approx. 0 deg., and oil flow control solenoid valve duty output approx. 10%?	Check the follow- ing and repair or replace if neces- sary. • Engineoil (amount, dirt) • Oilpipe(clog) • Oilflowcon- trol solenoid valve (clog or dirt of oil rout- ing, setting of spring, clog of valve) • Intake cam- shaft (dirt, dam- age of camshaft) • Timingchain (matching of timing mark)

 

That's from the FSM. They reckon check the oil feed line as well...

 

Thanks a lot, checking the oil feed line will be a mission as it goes down the side and under the engine... but I'll see what I can do..
