Here's an update on my 5/30 post about valve clatter. I took my 4 month old (3000 Miles) G80 Sport in for service on 5/21/18. I got it back today, 6/22. I was originally told it was defective CVVTs. After starting to tear the engine apart they discovered the problem was a manufacturing defect with the tappets on the valve chain. The tappets installed on my 3.3T apparently lacked a provision for allowing sufficient oil lubrication, hence the clatter. My service advisor advised that they found that 3 of the 24 tappets had been seriously scored due to insuffient lubrication. He said that it was only a matter of time before the other tappets started showing the same wear. They ended up pulling the heads and replacing all 24 tappets with new ones that have a new part number and that replaced the old tappet part number. What was most alarming was that this defect is more wide spread than I was lead to believe originally. I was told that it affects 3.3T's & 3.8's that were manufactured before they made the tappet part change. Since I took mine in a month ago, my dealer is dealing with a third 3.3T with the same problem. My only advise is that if you hear a valve clatter upon cold start up, talk to your service advisor. If he blows you off, talk to the service manager. BTW, because the G80 is so well insulated, that it is hard to hear the valve clatter from the drivers seat. I first heard it after I got out of the car right after starting it up in my garage.

When was the tappet change made? What is your cars build date? (Inside of drivers door)

Thanks.

Me build date was 6/2/17. I bought it in Feb this year. I was not able to find out when the revised tappets were released for production or to dealers. It sounds to me like Genesis should issue a recall or at least a tech bulletin.
