Just having the coolant system from my car (99 STS with 108k) drained and replaced while I´m away from the UK for a couple of weeks (first time it´s been changed since 80k at the latest according to the service book). When I dropped the car off the mechanic at the Cadillac dealership noticed a small amount of oil in there, and said that if it turns out to need it´s head gasket replacing then I should simply scrap the car. The car itself cost 2500 pounds/$5000. The reason being is that he said the head gasket parts required would cost a mammoth 3000 pounds/$6000. Now I´m no stranger to the cost of Cadillac parts, but is this an excessive price? Surely head gasket replacements are available a lot cheaper for me to import then get another non dealership garage to fit? I´m willing to get it fixed if it does turn out to be a head gasket going, but not if it costs more than the car cost me!
