I bought this 1997 Outback DOHC with 198,000 miles about a year ago. Just after purchasing the car I took the car for a road trip from Seattle to Santa Barbara while towing a 400lb trailer. About two hours from SB my car started to overheat. This was strange because I had recently had the radiator replaced. When I opened the hood the pressure cap on the radiator had fluid on it and the overflow reservoir for the coolant was overfull. After the car cooled, I took the cap off and started the engine while filling the radiator from the top. I nursed the car to my final destination. On the way home from this same drive I had another overheating when I pulled off the freeway and went to the gas station. I let the car sit and then the next day took it to a jiffy lube to have the cooling system purged and filled, eliminating any air pockets. I was able to make it the rest of my trip without any hitches but I still had suspicions. Since this trip the car overheated twice and then finally when I checked the car after another overheat I found oil in the coolant reservoir. Since then I have pulled the engine and got the heads off. I am not a trained mechanic and wanted to hear another persons opinion about my cylinder walls and heads. I want to know if it is worth installing new head gaskets on this motor or if I should search for a new block and machine the heads. Thanks in advance!
