Water Leak on Floor - 2006 Town Car

How do those who Silicone sealed that plastic trim piece in place expect to remove it for service, without the plastic breaking?
 
I do NOT recommend RTV or silicone or even butyl, 100% DO use a thick automotive grade EPDM gasket that way if you ever have to take it apart it won't be a nightmare, and it won't damage anything.

I used this product but in white https://amzn.to/3v49MaK - I have a couple of photos of the finished product here.

That is more like it! Has it been exposed to considerable rain and not leaked? Did it have the correct amout of thickness ("Crush" ) to seal yet not put too much of a strain on the plastic trim piece?

Please click on the current Amazon product in you LINK. It is now white (which is good) and advise if it is the same dimensions as what you purchased. Thank you very much. My 55,050 mile , garage kept 2003 Town Car is not leaking now, but I will do a "proactive" repair.

THANK YOU VERY MUCH.

At one time silicone was very bad for electronic engine sensors.
While silicone is curing, it off gasses and can damage some sensors. That may include interior temp sensors for the HVAC system.
I stopping using silicone a couple of decades ago. There are much better alternatives.
RTV being one.

OK I am not an expert on chemicals.

Given the choice, I would buy and use a sealant that does not have silicone in it.
Because it is known that silicone has do damage to sensors as far as their accuracy.
Not so much on newer ones because of the issue is know and chnages were made.

I just stay away from the stuff if it is listed on the contents of a sealer.

Some RTV Silicone and Silicone Spray Lube, WILL ruin O2 sensors. Some has been reformulated "Sensor Safe" or "Oxygen Sensor Safe".

Back in the 1980's I used Silicone Spray Lube on the rubber engine air filter housing to throttle body duct, on my 1987 Ford Taurus 3.0 V6. It ruined the O2 in a very short time, TWICE, before I realized what killed 2 new O2 sensors. (It was not well known then).

Silicone formulations were different back in the 80's. Remember when they used it for breast enhancments and it ended up being a toxic substance?

Today's formulations are much more friendlier
 
Each and every one, "oktowncar" ? Or do you have to read the product description, as I stated?
 
Today I installed the same weatherstrip/gasket 07-Town Car SL recommended. It fit perfectly with, I believe, just the right amount of “crush” to seal out rain water.

Ford used “open cell foam “ , which when compressed is good for low pressure air / wind leaks. that is the wrong type of gasket water!

Thanks, 07-Town Car sl !
 
The other night I read through all 8 pages of "tales of woe" on the infamous T'Car right rear floor turning into a "aquarium" during a rain!

Let me dig out pictures (from another 'puter) of long ago on how (two week flustrating process, + several gallons of dyed water) I found "my" leak, and where it was comming from! I found it quite by accident.

At the time, I did NOT know that 99.9% of every Lincoln T'Car had this leak! I tackeled it thinking my newly purchased car was the only one that had a missing hunk of seam sealer, or whatever.
 
Missing from what location, acchaplin?
No, sorry you misunderstood my statment. Since I did NOT know all the details about the 'leak'. (I was not on any Lincoln forums then. Dodn't even think there was a web site for the late model Town Car ) I 'surmised' the leak was a missing section of seam sealer. Since most leaks happen at a 'pinch weld section' that either the seam sealer was 'not' applied, (factory) or was applied (factory) improperly.

The day I discovered the back floor had 2" of water laying in it. I immediatly took out the back seat, saw no 'visible trails of water' and preformed a quick garden hose 'leak check' around the rear glass and rear door. Since there were no 'leaks' there, in the 'obvious' locations. (you know, rear, one side, that is the logical location a leak would be. You do not go into the kitchen to replace a light bulb that is burned out in the bedroom.)

I quickly took off the right rear scuff plate lifted up the carpet, saw that thick foam sound deadener was litterly soaked, left rear and, as far forward as I could reach. The ONLY way that carpet would thouroghly dry was if I removed it placed it up on 'horses' and placed box fans blowing up under it. (When I did that, it took 4, 24 hour days, fans never shut off, for that carpet to thourghly dry!)

It took several days of shuffling the garage around so I could place the car so I could dismantle the entire interior, and place everything so I could dismantle the center console and the passenger side front seat. For both the console right side mounting brackets, and the rear section of the front passenger seat mounts were very badly rusted! The right rear side console mount had started to rust away on the one edge. The rear seat frame was not corroded at all!

After sending those brackets and such off to be sandblasted and powder coated. The driver's seat tracks and bottom frame I used a scuff pad, and just 'rattle can' them real good.

I went to a custom leather shop and got a gallon of leather cleaner, and coditioner. After scrubbing, scrubbing and scrubbing some more, I got the seats 'very' clean and 'very' soft and supple with the conditioner. I used 8 cans, (6 with the carpet on the garage floor, 2 with the capet in the car), of Resolve Heavy Traffic Pet Stain Remover spray carpet cleaner. Along with one of those hand held carpet scrubbers that had the roating brush heads, and a rather stiff hand held brush.

Befor I installed the refurbished light Palomino colored interior, and the extra sound deadner, is when I did the leak checking and took all the pictures. (which I can't seem to find right now)
