I have an F6 as well . Both are silverThis one was the old which came first chicken or egg. We believe some time in the cars early life its was over revved causing the loosening. Possibly a missed gear. We got it at 1500ks.Did this as well. But which first, flywheel or balancer Link to comment https://www.fordxr6turbo.com/forum/topic/84568-loose-flywheel-bolts/page/5/#findComment-1461347 Share on other sites More sharing options...

A big heavy steel harmonic balancer should help that. The whole crank assembly namely crank, h/bal, flywheel, clutch need to be balanced really well on a modern machine. Its alot to do with crank harmonics and balancing and not being a fully counterweighed crank like in the EF/ELs does not help either.

Threadlock was the first thing I did years ago. Harmonics will defeat it.

Anthonyfgxr6tute New Member 2 Member For: 7y 11m 8d Posted 27/06/17 09:55 AM Share Posted 27/06/17 09:55 AM I've also got the flywheel bolt problem.It's an fg xr6t ute 6speed & It's running a mal wood option 3plus kit.One of the bolts snapped & ruined the clutch ,flywheel & crank.So I've replaced them with a new clutch, flywheel & I also put a new f6 engine with 20 000ks on it in.This time the bolts where tig welded around the head of the bolts which was recommended by several reputable builder's. Well now I'm in the process of putting a built engine in so the old one came out the other day.When we pulled the box out we noticed that the clutch plate had grooves & marking on it like it's flopping around.Would this be where the vibration & imbalance causing the flywheel bolts to loosen be from?or would that stem from something else?Any help on the subject would be awesome thanks.
