I dont think that just re-tightening the bolts will fix the leak....It didnt on mine. Just replace the gasket like me and gearhead are doing. The new one is only $25 and supposedly you dont have to lift the engine. Im gonna try that this weekend. Chances are that your gasket is worn out and it needs to be replaced. The OEM gaskets are aluminum and rubber so over tightening it will definately squash it.
