I am the very proud owner of a 1990 Subaru Legacy L Wagon with 232K on it but I find myself at a crossroad. You see, at the moment it smokes sooo bad that I could sell it to the marines to drive into the middle of combat and use it as a rolling, dependable smokescreen. The family who owned it before me took real god care of it. They installed a new water pump and timing belt not to mention lots of other new parts. It seems that oil is leaking somewhere behind the black plastic guard up front and leaking on to every single inch of the exhaust and putting enough 10W-30 on the road to classify my vehicle as the next Bond car. So my question is......How hard is it to change those leaky seals??? Anyone do a write up or tech article on it with step by step instructions? Is it ion the Chilton? Any special tools required? this is my daily driver so I can't have her apart for a week. I am handy with the steele (chrome plated) so I am not too scared of getting the hands dirty. Any info would be much appreciated. Thanks, Greg coloradosubarules@yahoo.com
