SOURCE: Oil running out my tail pipe
Excess engine oil can only enter combustion chamber from four areas, (1) the intake manifold [pcv system failure], (2) Valve stem seals worn out [pluged oil return holes in heads causing oil to get sucked past worn seals] (3) Worn/varnished up/broken piston rings,(4) Highly unlikely but a hole in piston. Since you only show excess oil on left rear, suspect #2 or #3 although usually more than one set of rings will wear out or (gumm up).Check compression with all plugs out, ignition & fuel disabled, i believe 120 to 150 psi is good, if ok , check #2. If this has the older efi intake, its rare, but also could have a failed intake gasket for that cylinder and be sucking oil from underneath.Hope this helps!

look for block return lines- air leak in suction lines -block fuel line or filter - defective injection pump -inoperative glow plugs.

SOURCE: 1993 honda accord burning oil
worn piston rings produce blue smoke all the time especially under acceleration. time for another rebuild or total replacement.. i am not very familiar with metric but thet is still a lot of miles, replace the rings, or replace the engine, or replace the car. it sounds like it is well worn

U got a bad piston rings! U have to pull down the PiSTON to replace the PiSTON RiNGS, oil is getting in ur combustion!
Check also the valve guide oil seal, hope that is the faulty one! 'Cause replacing PiSTON RiNGS will cost a LOT!
Check on that first, Oil in ur air filter means a BLOW BACK gas from ur combustion is pushing the oil into the air filter!
BLOW BACK is a residual combustion air that should have been burned or gone thru the exhaust, but w/ poor seal of ur piston ring, it goes into ur CRANK CASE and into ur EGR system w/ excess oil!
Hope that explains everything!
