Well I just finished talking with my mechanic. I asked him to put new rings and seals, gaskets and whatever ells needed. Today he told me that I need new pistons. I dont understand this, because the engine runs fine in the summer. In the winter it will start hard, and thats the winter. Can it be the pistons are that bad? Never have problems in the summer, and it never blows smoke from the exhaust, except when I floor it. I am unhappy because this will cost a lot of money. Can anyone tell me what a set of pistons with rings might cost? Thank you for your time and help. -Nick
