I've had re-occuring problems with this guy. Once, I was getting an oil change at a local Valvoline, and the technician noticed some dark substance in my coolant reservoir. He told me to get it checked out just in case, for it could be a sign that oil is leaking from a crack in a seal of the head gasket. I took this to Kevin at Upstate Onsite to perform the necessary tests and he jumped on the opportunity to convince me that my head gasket MUST be replaced, $2,500 he quoted me to do the work to make my vehicle safe again. He made it seam like my truck was a ticking time bomb, unsafe to drive with my children. When it comes to this kind of money, I took it for a second opinion. I was shocked for them (second opinion mechanics) to inform me that the leak-down test had indicated that NO oil was leaking and that my seals were tight and strong. They told me that cracks in the head gasket aren't even common in my make and model of truck, and that my truck was safe and good to go. I've put 3,000 miles on my vehicle since then, and my truck is still running strong. Just because I don't know much about automotive repair, does NOT give him the right to take advantage of the uninformed. read more
