My son was fighting gremlins on a ford I said head gasket, he worked on it for a couple of weeks. I bought the kit, he did the test and confimed it in a couple of minutes.
We have one old school station in town that is owned by a friend of mine, no ethanol at all in his place. I haven't spoken to him about the new mandate but I'll see him in a few days and will ask.
I just found an 04 with 113K miles, It's from Oklahoma so it has a few hail dings and was in a pass side wreck with a less than perfect paint job. The engine and undercarriage are absolutely spotless. :banana:
