Hi will my 2012 FL2 SD4 have swirl flaps in the intake manifold???
?????*snigger*
Most are plastic and sometimes they break off and enter the engine.would they be the silly plastic ones that become brittle and break off or will that problem have been sorted out do you think ??
yes thats what happened on my last FL2 How big a job is it to have the manifold taken off and checked and cleaned out now and againMost are plastic and sometimes they break off and enter the engine.
That's an interesting link, those flaps look like a ticking time bomb.
From that link it looked like they may have stopped using them at a time before your's was built - but it sounds like they are actuated by vacuum - so is there any vacuum pipe going to your manifold?Hi will my 2012 FL2 SD4 have swirl flaps in the intake manifold???
Sounds like everyone on that thread who had them removed was running fine. i know what I'd do as a first job having got an F2!yhis is why i asked the question because theres a grey area as to weather you can run them without flaps or not
