Ja točno to je problem, olje teče mimo in ne skozi variator (kakor je pri Nord motorjih).
Problem olja na min je to, da se precej bolj greje, s samim variatorjem pa še vseeno nima veze.

Closed Phase
When the closed phase is required (idling and full power area), the electromagnet (1) is de-energized, thus the valve distributor (2) pushed by the counter spring (3), stays up preventing the passage of the oil leading from groove (A) from reaching the variator. In this case the timing of the intake valves remains unchanged (closed).
Open Phase
If the open phase is required (average speeds at high torque), the electromagnet (1) is energized, thus pushing the valve distributor (2) downwards. In this position the oil, leading from groove (A) enters chamber (B) of the piston, from where it passes through a special hole intro groove (C) machined inside the latler.
The oil can only leave this groove through the upper hole (in communication with the oil delivery duck (C) to the variator) as the lower hole no longer leads to the exhaust duct (E) because the valve distributor (2) is lowered. The oil passes through duct (D) and (F) and reaches the chamber (G) moving piston (4) axially towards the engine. The outside piston (4) is fitted with helical teeth and as a result of the above-mentioned axial movement it is force to move clockwise (as seen from the timing side). The rotation is transmitted through a straight-toothed grooved profile to the pinion (5) which is screwed onto the threaded lug of the camshaft (6) and transmits rotation to the shafts. This way the timing of the intake valves are changed by 25º.
When the electromagnet is de-energized, the valve distributor (2) returns to its initial position, shutting off the flow of pressurized oil to the piston (4), but allowing the oil to return to the exhaust due to the thrust of the counter spring (7).
