Blowing off cap on throttle body servo drive?

[IHeartGroceries]

Dang. Guess I better go check under my hood. Haven't poked around under there in a while!

I think it could be from shutting the throttle plate under high boost. The pressure build up cannot be related quick enough so some escapes though the servo. I'm not sure anything but a very serious adhesive will keep it in place. Then you will never have access to this point. I think it's best to leave it off.

I do not wash my engine bay so I am not worried about water.

That cap sure does not look like a reliable source of a air pressure seal,that cap should be addressed and updated,looks more like a cap from a can of WD-40.

The seal should be in the servo. But if boost blew the cap off then boost got past the seal.

Yes, it looks like a dust cap. Not for serving as a seal.

I agree the the cap is not substantial, but there is an o-ring that seals the cap to the housing. This may be more for keeping water out than keeping boost in.

Looks like we need a volunteer to ride under the hood for some first hand testing....lol
