- LaCrosse 2013
My lube tech advised the last 2 oil changes that I have a leak at the timing cover gasket, 1st noted at under 50K miles, now 54K miles. He advised that this Buick engine has a history of this problem and that Buick may have some extended warranty program in placefor the repair. Does anyone know or is anyone else have this issue?
