95oldsVan Posted March 28, 2006 Report Share Posted March 28, 2006 In the process of tearing down the 3.1 Grand Prix engine,I took the balancer main bolt off today and a bunch of oil came out of the hole from the snout.I never seen this much oil come out of there...im starting to wonder if a possible crack in the crank somewhere...or if this is normal or not on these engines...maybe a bad front seal?If so,how can so much oil get inside the crank bolt hole? Any ideas? Either way,the tear down continues.... Quote Link to comment Share on other sites More sharing options...
