3.find a banjo fitting to vanos oil port, blow high pressure air to vanos, while use battery power to activate intake and/or exhaust solenoid. it'll free the vanos anyway. if it works, you can hear the cam shift sound(open the valve cover can let u easy tell if it works). related video u can find on youtube by searching bmw double vanos. banjo fitting u can buy from ebay or anywhile u can find, I just made one from old broken hoses.

For clean up head, u can either open the valve cover(need change valve cover gasket which is cheap and easy to do), clean it phsycally; Or use any engine flush product on the market after u can start engine and right before change oil.

Good luck.
Projects, I did the compression check and confirmed the weird results: all were between 60 and 120 psi, which I assume is way to low. Is this the fitting I need to unhook then blow air into (pic below)? So I need to rig up a banjo fitting to an air hose to get some good air pressure in there, correct?
