3Katz Donating Members 122 Member For: 7y 3m 18d Posted 27/01/22 01:40 PM Author Share Posted 27/01/22 01:40 PM No I haven't found the problem unfortunately. I took it to a tuner and we put a set of chassis ears all over the engine and still couldn't determine exactly where the noise is coming from. We replaced the balancer, tightened the cam chain an extra click and no difference. The engines been pulled down twice and everything measures up fine. I've had a clevo before with noisy forgies and I certainly agree that's what it sounds like but on the clevo the rattle went away once they were up to temp. And they all made noise wheras with this, if it is piston slap it sounds like it is just one piston. And it doesn't go away/lessen when hot. Mate I'd be happy to send you a keg of goon, in fact I'd be happy to pay for your flight to and from Bundy, a motel stay and a rum factory tour for you to come and disgnose this lol. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710234 Share on other sites More sharing options...

If you want I know bit of pain change the chain tensioner to factory tensioner and See if the noise still exist. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710235 Share on other sites More sharing options...

I put a 71c thermostat in it when I built it and I reckon if I put a 80+c one in, the noise would go away. Dunno if it would cos I never got around to changing it, but that's what I reckon would happen. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710250 Share on other sites More sharing options...
Tom Tucker Donating Members 703 Member For: 5y 10m 23d Posted 28/01/22 11:14 PM Share Posted 28/01/22 11:14 PM I have similar timing chain/tensioner noises. It's pretty common with stiffer valve springs. I wouldn't worry too much 2 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710264 Share on other sites More sharing options...
3Katz Donating Members 122 Member For: 7y 3m 18d Posted 29/01/22 08:23 AM Author Share Posted 29/01/22 08:23 AM I forgot to mention the Atomic tensioner has been replaced with a factory one already. I have a low temp thermostat in as well - changing it too a higher temp one is a good idea which I'll try. I'm almost at the stage of taking it back to the tunner and just getting into it and seeing what develops. The problem is it's a real nice ute, and sounds like a bucket of sh#t so it's not as enjoyable to drive as it should be.

TBRE won't use them they are huge overkill even for big builds. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710266 Share on other sites More sharing options...

Might be on the money, or it was something completely different.Done 35k like it and still going so meh 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1710269 Share on other sites More sharing options...

Having a very similar issue built atomic motor stock chain and tensioner though Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1713937 Share on other sites More sharing options...
3Katz Donating Members 122 Member For: 7y 3m 18d Posted 22/08/22 01:08 PM Author Share Posted 22/08/22 01:08 PM Not yet, it's got everyone stumped. Went back to the dyno and got all the low speed tuning done but have a wastegate issue to sort before getting stuck into it. Going to ignore the noise for now and see if anything develops 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96403-what-is-this-noise-carton-on-offer/page/2/#findComment-1713940 Share on other sites More sharing options...
