Well my daughter finally killed it. Her 97 Outback had a slight knock during start up after it sat a couple days after I changed the head gaskets. I had told her to check the oil every time she got gas. Needless to say she did not always having an excuse. Well last week I heard it knocking every time she started it up. It stopped as soon as the oil pressure came up but I knew it was a matter of time. Her Grandmother was saying how proud of her she was when she stopped to buy oil when the oil light came on last week. Needless to say I was not proud at all. Last night I had to run out and get her off the side of the road. It is knocking all the time and will not stay running for more that a couple minutes. I am happy I save the engine out of the donor 98 that supplied her transmission. That engine will end up in her car this weekend. I dragged the car home the few miles this morning. Merry Christmas to me.
