could not talk to mechanic only the receptionist. she said HC particulates in car and then driving caused blown head gasket. I thought the HC was a sign of blown head gasket overheating or not. If not then where did HC in radiator come from. her answers were circular and shop seems extremely busy with one mechanic

Expert:  ConditionedAir replied 1 year ago.
It needs to be in the "car" category. This is heating and air conditioning experts.

Hi, welcome to our site. I am a Certified Master Technician with 30+ years experience and I will do my best to assist you. Please keep in mind that, while I can provide you with technical guidance, working on this type of issue may require you to have not only access to several different automotive tools, but the skills to use them as well. As I’m unable to hear, see or touch your vehicle, it is very important that you provide me with as much information as possible.How can I help you?

I took the Pontiac to mechanic and was told that I had a blown head gasket based upon hydrocarbon particulates in readings taken these reading varied from 3 to 21 ppm. Is this definitive? while I can pay there first est of 1300 to 1700, they raised it based upon the make of the car to 2500.00 + I realize this is an expensive procedure but I am not knowledgeable enough nor to I have the equipment to attempt anything myself. That is all that I can tell you

Oh it is 2008 Pontiac grand prix v6
Expert:  Juan Crespo replied 1 year ago.
In cases such as your vehicle's, where the HC shown are minimal, I always advise using a chemical such as Blue Devil Sealer (click here to view offering from Advance Auto) as the first method of repair. I've had great success using this product and thus have saved my customers thousands. The only caveat is that instructions printed on the can must be followed to the letter; no deviations or shortcuts. Best Regards.
