Wind Noise

I get a ton of wind noise from where the conv top meets the windshield when driving over 60 mph. The header bow seal is new. The top latches are pretty tight, maybe too tight for the new seal or is this noise to be expected?

I've only had the top up once before, it was pouring rain then and I was more concerned about the water getting in past the old seal!

Also, what's the recommended lubricant(s) for the top joints and cables?

Thanks.

I used to wedge foam in the space. The type of stuff you put around an air conditioner in your window. In the winter I'd put even more in because a flake or two would get in while I drove at 60 mph.

 

We get so much noise in our 68 convert with a new top at 60 mph that we can't hear the wind. Its a new top and I had it tightened up after this occuredd but it is still noisy. Seems a bit better with a side window cranked down about a 1/4 inch. I have been told it is normal noise but because it is so annoying we drive with the top down unless absolutely necessary to put it up (rain, snow ,,,)

 

do you have a gm manual that covers convertible tops for scissor top cars?

in order for the header seal to work correctly, it needs help from other parts of the top and frame.

first off, if side tension cables are broken, they will allow air to "bubble" the top canvas up at higher speeds pulling the header seal from the windshield frame letting air/rain/ect. slip through.

also, if someone has ever tried to put the top down with the latch disconnected but with the handle in the latched position, they may have bent the metal that supports the plastic "cam" (see picture). this cams job is to help maintain slight pressure on the locked handle causing a pivot at the front hinge that helps the header seal maintain its pressure.

and one more thing. the front roof rail weatherstrip (the spongy thing covered in top material) needs to have about half of itself smashed by the header bow when the top is latched, this weatherstrip it your FIRST defense against air and rain. sometimes due to age this foam it will give up (stay smashed) and not apply enough pressure. if it is no longer "springy", the foam strip may need to be replaced.

 

Yuk, thanks for tips! It will give me something to do while I'm waiting for this rainy weather to pass.
