Ole reliable had to tow her home today. Guessing i blew a head gasket on my way in to work last night. Motor was hydrolocked in the parking lot, guessing it filled up during the shift since it didnt overheat on the way in. Towed it home, its at the garage door now awaiting repairs. Drained a gallon of coolant out of the oil pan! I wont really be able to tear into it next week, but im guessing passenger head gasket. Got all spark plugs out in parking lot at work except #4 as i didnt have a socket that would clear the header. #3 was was sparkly, like it was burning coolant. Guessing #4 will be as well.
