Damn that sucks, good luck with them Gents. It seems that they're keen to tell us that they've never heard this problem before and that we're hearing things or whatever, i wish they'd just sort the problem and be done with it.
Heres a recording i did last year before they replaced the lifters
After replacement it was quieter but its now getting back to this level again, and sooner than it did last time too.
Thinking about it, i am dissapointed, but being a seriously long term Holden owner, i'm also deeply embarrassed by this engine / car. I live in a pretty prosperous small mining town, i have had people change there minds about buying an AFM v8 after hearing the racket mine makes, and i'm sure its hurt the sales at the Dubbo holden dealers too. And you know i cop a fair bit from the local Ford guys, which is getting irritating.
By the way a mate in Sydney said that the motoring writer for the Telegraph did a write up on this problem a few months ago?
Of course the fix is easy, i just replace the lifters and cam with something better and bingo the problem goes away. But that means disconnecting a system on the car thats supposed to work, dammit. Anyway, post up your vids here of your rattling engines as i'm writing a letter to GM at the moment and i will be mentioning this thread, who knows maybe they'll look?
Cheers
