Had my aveo 2011 1.6 G3 for about 4 years now.
One big pain with it is the notorious valve cover gasket.
I follow all the steps carefully while replacing it. Super clean surfaces, correct torque and sequence etc.
Tried various amounts of silcone gasket around the half moons.
But as always after about 7-8 months of heavy use it begins seeping a film of oil down the front, always starts off in the right corner, then slowly spreads.
I change it every year!! Seems to go quite hard after less than a year which I assume causes the leak..
Tried original gaskets, aftermarket ones also. All the same.
Is it just a serviceable item that needs replacing every flippin year??
