2001 forester head gasket issue
One shop told me that I needed it fixed in the next 6 months or bad things would happen. He did not expect to do the job so I don't think his assessment is biased.
But my regular mechanic looked at it and said it was no big deal. He told me to keep an eye on it, but that the condition would not necessarily get worse or that it may take a long time to do so.
Since I have no expertise in these matters, any thoughts you may have would be appreciated. I obviously prefer the second opinion, but do not want to screw up the car. The seepage is oil, and thus presumably not subject to the extended warranty by Subaru discussed in previous posts relating to coolant.
