just gave my car a mini service this weekend, oil/filter cam gasket and clean all the breathers out.
first up the cam shaft was looking quite scored and the tip of the lobe looks to have worn maybe 0.5 mm apparantly its 6.67 mm lift so this could reduce performance no? not a very scientific test as i just compared the lobe against the untouched material either side that doesent contact the follower, no ticking on start up though.
oil was as usual very black even though changed regularly (15/40 magantec) oil pressure recently has dropped to 2bar occasionally at idle (normally 3 at idle) and idle/speed seems a touch low/rough around 800rpm ,cleaned icv out bo joy there.
still getting very intermitant code 48 (low battery voltage) when it happens battery seems to charge around 11.8v at idle then when engine light goes out charges around 13.6v both measured across battery terminals , also when light comes on, idle goes all over theplace??
