95oldsVan Posted March 28, 2006 Report 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
