Bill, there is a spring that holds the flap in the closed position until the RPMs get high enough for the valve to open. Best I can tell from what you have posted, there is nothing wrong with your flap.

Go back to my original post. The operative word is "stuck". There is a distinct difference between held closed by a spring and stuck. Also, start reading between the lines. When a person says "Had the exhaust system off the car yesterday to perform adjustment to shifter . . . ", it is reasonable to presume that such a person might know a bit or two about cars and perhaps even a thing or two about what constitutes "stuck". Let's see what people who have experienced the problem have to say. |

Had the exhaust system off the car yesterday to perform adjustment to shifter and further examined the valve.
No corrosion, no evident reason for it to have been stuck. Hmm? I am getting ready to install a RE SSK/WSR on my 550i soon. I noticed you had to make an adjustment to the shfter. What kind of issues were you experiencing that required you re-visit the installation? Sorry for hijacking your thread. al |

Biff,
I am getting ready to install a RE SSK/WSR on my 550i soon. I noticed you had to make an adjustment to the shfter. What kind of issues were you experiencing that required you re-visit the installation? Sorry for hijacking your thread. al The RE SSK/WSR is great. Had one on my e39 540 also. Adjustment that I made was to put about 5 degrees of forward bend in the shift lever just above the pivot ball. This moved the pattern closer to the dash which is a personal preference issue only and not an issue with the SSK. PM me with any other questions on the SSK/WSR. |

I noticed that mine was also 'stiff'. Operating the actuator by hand was very difficult - it also felt like it was rubbing sometimes when manually opening. (like grit was present).
With the level of friction, I don't think that a vacumn actuator could open it - although I can't think of a way to check this. In the end I strapped mine in the 'open' position - this increases the V8 'rumble' at tickover, which I thought was lacking somewhat (there are other posts on people fixing this actuator into the open position.) I prefer the addtional tones, but I do think that the torgue has been reduced slightly (at low revs). However, having the valve held open is probably better then having it stuck shut. What about a high temp silicone grease? |
Someone wiht a new 550 test their valve and tell us how many Newton Meters of Force it took to open it.
