It's fairly simple. M/B screwed up with the seals at the factory. The seals had the adhesive on the wrong side of the seal and the adhesive side was attached to the tail lamp instead of the body. And for that reason many 164 models suffered water entry.

Order both seals, 164 826 15 91 & 16 91, $38 each, and make sure the gasket is attached to the body and not the lamp.

 

Thanks. I didnt notice how the gasket was installed from the factory. In any case would it be wise to just put the new gasket on the body and still use the old gasket on the tail lamp so it would create a double seal? I think the screws can seal it with tightness. Just a thought?

 

Hi ZFT:

There is another option you may wish to consider, and that is applying some dielectric grease to the rubber seal.

Dielectric grease contains silicone, and will not deteriorate the rubber gasket.

Quite the opposite, dielectric grease will keep the rubber gasket in good, pliable condition, and will provide a resistant barrier against water intrusion between the rubber gasket and its mating surface. :smile

Dielectric grease is relatively cheap, and easily found at most auto parts stores.


Try it.... you'll like it! :wink

I just did this at my last service. It wasn't too terrible. I've only had water intrusion on the right hand side so that's why I only did that side. If I notice anything on the left I'll do that one as well.

Hi , you mean to do this on the new gasket or can be done on the old gasket sticked on the tail lamp?

 

After removing both tail lamps, you will see a cavity/hole with the same dimensions as the seal. Peel off the tape and carefully place the seal over the cavity. Make sure you do it right the first time because it will be very difficult to remove it without being damaged.

 

thanks 43sqd. ill try it on the right side first. its the most concern right now due to rain. thanks
