Sunroof rear gap - 81 911 SC
I just replaced the sunroof felt seal per the host recommendation on my 81 911 SC
Unfortunately I have a gap between the sunroof and the roof in the rear section. The front seems nice and snug and may be able to move back slightly to help alleviate the rear gap. Any idea how to lessen this gap? Front Gap (none): https://i.imgur.com/XQNM2h2.png Rear Gap: https://i.imgur.com/G0yyUCe.png

open partly the sunroof..pull down the headliner-look for some loose nut in there..if it is all tight unzip the headliner to access the motor for the sunroof.it is possible one of the cables is broken -the left one...and report..

Hey Ivan, the sunroof operates normally. Opens, Closes. etc.
It is just the slight gap I am trying to get rid of. Seems like when it is completely closed it is slightly too far forward. |

in that case unzip and open partly only a little bit..you have to loosen the motor and close manually then reattach the motor....best to this if you again,take the headliner down and once you have the motor loosen close it by hands so the cables are aligned...when it closed the final thing is push up the cable sliders forward so the roof goes up..

Sorry for my ignorance Ivan, but that seems like it wouldn't solve the problem.
The sunroof closes without a problem. There is just a small gap now that I have installed the new felt seals. Perhaps there is some alignment that can be done without messing with the motor? That seems like it is unnecessary to mess with the motor to try to solve for the small gap in the rear. Note that the gap is not because the sunroof is not pushed up all the way. The gap is from the sunroof being too far forward. |

that is the reason to readjust -synchronized the cables ..it is about the motor catching the cables in the same time..

Gotcha gotcha. Makes sense. Let me give that a shot and report back!

Welp, no luck. Tried taking the motor off, adjusting the roof, putting the motor back and next time I closed it it went back to the same large gap in the rear and no gap in the front.
Tried this multiple times to make sure I was doing it correctly. Anyone know if the rubber part is suppose to stick above the roof itself or flush with the roof. I am betting I installed it wrong. Likely needed to move it down and have the seal sit flush with the roof. |

Ivan - Yeah, I tried that about 10 times. No luck. I honestly think I mounted the felt incorrectly.
I think the rubber tubing that the felt wraps around is suppose to sit at or below the roof line. Attaching a diagram of what I mean. I think it should be placed with orientation A,D or B,D. What I did was A, C. I am going to take it out and retry with B,D unless anyone is aware of the correct orientation. Diagram: https://imgur.com/X7Qm1lN |

Definitely flush with the roofline.

Post some better pics that would help. One with the roof open and one with it closed.

Another picture...
The rubber sitting above roof line. Likely to be sitting below the roof line and should not be visible from an angle like this. https://i.imgur.com/aqBjq0Z.jpg |

Your photos are horrible. You have to be able to do better than that.

I think your front seal is way too high. As others have said, it should be flush, or just ever so slightly, above the roof line.
