Are you suee about HEAD GASKET and RINGS? If driven with light flashing cat. converter damage may occur!
Just called mechanic who did plugs he is fixing gasket and rings this weekend.Oil got into pistons when plug was pulled he claims no damage will come of this at this point .Iwill not drive the car till it is fixed.Don't trust more damage will occur.Thanks for info.Don't know who to trust anymore.Cars are a necessity not a luxury!
I agree! However I think your problem is your VALVE COVER gasket rather than head gasket OR rings! Defective or worn out valve cover gasket will allow oil to run into spark plug chambers!
