steve56 Posted March 30, 2019 Share Posted March 30, 2019 (edited) Bought 2001 Legacy with external head gasket leak. Just got anti freeze in the oil. I thought the 2001's didn't have the have the internal leak problem. Whats the best procedure for doing the head gaskets now that the antifreeze had mixed with the oil.

montana tom Posted March 30, 2019 Share Posted March 30, 2019 If it mixed bad enough, then there is most likely bearing damage. Otherwise, if you think its ok , flush it out , then use #642 Subaru head gaskets . Myself , I would search out a replacement motor. 1 Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 30, 2019 Share Posted March 30, 2019 Any engine can get an internal coolant leak from a blown head gasket - that’s exactly what a blown HG is all about. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 30, 2019 Share Posted March 30, 2019 They didn't fix the coolant leaks till 2002. 99 to 01 models leak coolant and oil. Replace the head gaskets. GD 1 Quote Link to comment Share on other sites More sharing options...
