Broken Stud in Throttle Body

[65cobra1]

The other day, came back from a run and checked over the car...The air filter was twisted and loose on the Roush 342RE motor.

The air filter adapter stud had broken off inside the throttle body!

I removed it and am waiting for a call-back from the people at Roush.

Has anyone experienced this problem? If so, other than replace the adapter using the same soft aluminum billet piece, what did you use?

Below are a couple of pics showing the broken piece and where it was located.

The 1st shows where it snapped off inside the throttle body.
The 2nd shows the billet piece plus the screrw that goes thru the filter into the adapter.
Last is the piece that snapped off.

I will apreciate your feedback and...
Thanks, Ivan

I'd be more concerned about the little chunks of the stud that went down the throttle body.

As far as I can tell, it looked like a clean break. Before I drilled it out I blocked all four intakes.

That said, you have a good point. I cannot positively know whether or not some small piece of aluminum went into the motor.

I'll mention that when I talk to the people at Roush.
Thanks,
Ivan

Hi Gang,
I have a 342RE Roush motor w/ fuel injection.

The air filter system consists of an adapter that screws into the throttle body then a long screw goes down thru the filter and screws into the throttle body.

The stud in the throttle body broke.

When I removed the broken end, I noticed that it was a cast aluminum piece not a machined billet.

I've been talking with Roush engine department people. They told me that they got the part from a vendor but will replace the adapter with one made of machined steel OR they will manufacture a long screw and eliminate the adapter.

They said that my adapter was "The first one they have seen that broke."
(Hmmmm)

I'm posting this just in case you have a similar adapter on your system.

Have a happy 4th!
Regards, Ivan
