Landrover Posted March 10, 2022 Share Posted March 10, 2022 I thought I share this with any Chevy GMC Duramax owners. While doing routine maintenance on my 2017 Chevy Duramax. I noticed a small oil leak at the front of the engine. I suspected a bad crankshaft seal. Under warranty the Chevy dealer confirmed a leaking front crank shaft seal. That was the easy part here’s the nightmare. I was informed that the harmonic balancer pulley which has a rubber grommet in between the pulley for engine vibration was deteriorated and needs replacement. I was told I was lucky to have brought it in. If the pulley let loose it would have destroyed the engine. Speaking with the mechanic he said several like this has been reported. The bad news. There is only one pulley available at a North Carolina dealer and they refuse to sell it to my dealership. GM has zero available and are looking at 12-16 weeks maybe. I have started the complainant process but it also takes time. GM no longer will give you a loaner vehicle of the same kind you get what they give you. Which is wrong but better than nothing. The other sad part is there are no new trucks available to buy. 🤯🤯 There are better quality pulleys out there after market at $500.00 range. In negotiation’s with GM they may reimburse this cost to me. It’s not like GM to do this but we shall see. The battle continues.🤪 It looks like my Oliver travels are on hold for awhile, with the fuel prices this all my be a good thing. 😇 1 3 7 Grant 2022 GMC Denali 2500 HD 2019 Elite 11😎 Link to comment Share on other sites More sharing options...
