blackbfute Member 5 Member For: 17y 10m 14d Gender: Male Location: Brisbane Posted 21/04/08 10:59 PM Share Posted 21/04/08 10:59 PM Thought I would post this one for you guys... I put new injectors in my ute about two weeks ago, put in the custom 15psi tune and went for a drive. It's a Bf series one, 6 speed auto. I've been running the 12psi tune for about 18 months.Got the injectors in, went for a drive up the mountain near us (mt nebo), the car ran well, was very happy with it's preformance. Took it home and wrapped it up for the next day. Day two and I wanted to see what it really went like, so I stopped and nailed it to the floor. It took off in clouds of tyre smoke, then there was an odd noise - like I had dropped a bunch of sockets into the engine bay. I slowed down, no worries, all drove normal, foot down - no worries. That's odd I think to myself. Pull up at the lights and it sounded like those sam sockets were beign thrown at the panels - people down the road were looking back to see what the noise was. The car was shaking and I was worried - could see an atomic engine on it's way. Bumped the revs up - noise gone. Back down - and it comes back. Well I stopped driving it, pulled the fans out and turned the engine over by hand - I could definately hear something being picked up and dropped. Off to my mates workshop... He looks it over and rings me back - sounds like a torqu convertor - I'll pull the box and we'll see what is going on - I get a photo and a phone call with him lughing his head off. Turned out - all, yes ALL but 1 flex plate bolt had fallen out. The last flex plate bolt was just hanging on. Has anyone else had this? They weren't broken or stripped, just rattled out - I suggest a co-incidence that it happened at the same time I bumped up the boost etc, but what the - ahow the hell could that happen? The box has never been out of my car, so is it a ford problem? Never the less, I'm paying for a new flexplate, bolts, and rear seal while the box is out. And a bottle of loctite ;-)Jim Link to comment Share on other sites More sharing options...

IIRC at one stage fraud service where removing the boxes and loctiting are retorquing the bolts. I have also heard of people who are running big HP through the six speeds are tack welding the bolts.Luke Link to comment Share on other sites More sharing options...

Interesting to hear it's common, I was wondering why I was the only one who had experienced this issue.JIm Link to comment Share on other sites More sharing options...
