JOP3 Posted October 13, 2007 Share Posted October 13, 2007 This is my inaugural post on any forum, anywhere and it feels good to be amongst folks that understand "The Car." I've got a 2005 Caterham de dion, with a Ford Zetec SVT 2.0 liter and a lightweight flywheel -- and even more to the point, a ZF limited slip differential. I've only got about 500 miles on it and the only thing that bothers me a little is that when the drive train is not under load, it makes this sound. Doesn't seem high enough frequency to be grinding, but not low enough to be called a rumble. I've got Amsoil EP lubricant and the LSD additive that came with the unit in the pumpkin now. Don't know if I just need more miles, 30 minutes of figure eights or just the understanding that "this is normal." If someone has heard of this before or if I've left of ALL the real important info, please let me know. Thanks for the help. I'm sure to keep reading and maybe this won't be my last posting. -JOP3 Link to comment Share on other sites More sharing options...
Al N. Posted October 13, 2007 Share Posted October 13, 2007 JOP- DO you have the Cat 6 speed box? Regardless, does putting the clutch (even if you're in neutral...no load) in kill the rattle? I say all this, because I have the 6 with a lightweight flywheel and my box rattles a lot when you have the clutch out and are in neutral. So much so that my very experienced mechanic (though not necessarily with Se7ens...he only services one other) didn't want me to drive it at the Dragon. But a quick search on BlatChat (the UK club site) revealed that TADT="they all do that". Especially apparently if you have a lightweight flywheel. Scott L. had a similar rattle and I think they wanted to take apart his gearbox. When I was down at the Dragon, I left my car idling and some of the guys asked me "What the hell is wrong with your car?" Seth of BAM (Canada), asked about the flywheel, and when I told him I have a lightweight one, he said..."Yeah, that's typical." That said, check your gearbox fluid too. Oh, and welcome aboard. I certainly hope this thread's not your last.:thumbs: Link to comment Share on other sites More sharing options...
