KHE Posted November 13, 2012 Report Share Posted November 13, 2012 No repair in a bottle is going to work. I would not waste any more time or money on that car. Who knows what all the snake oil did to the cooling passages in the heads and block. You could try back flushing the heater core but if it doesn't clear up, it would need replacing which won't help the leaking head gasket.

Thanks, back flushing the heater core may be logical step before junking it out. Link to comment Share on other sites More sharing options...
KHE Posted November 13, 2012 Report Share Posted November 13, 2012 My response should have had the preface: If you are not going to repair the engine properly, I would not waste any more money on it.
