Hi Guys
I have a 2007, Signum 2.2 Direct GT with a Z22YH engine, 155HP, aproxx 130,000 miles.
It started using an imporessive amount of oil (20-50W), like 4 liters per 1500 miles.
There is no oil in the coolant
It does not "smoke blue and white"
Can worn piston rings or valve seals really be the reason for the consumption of that amount of oil ??
Had it on a lift, no leaks found, no oils under the engine
Any of you had any similar experience ??
