Default Re: Water leak on Floor from Rain

After a lot of searching... I found a rusted out spot in the firewall on my 68.

It wasn't visible from anywhere... and I kept caulking seems to no avail...

Anyway, I had pulled the carpet back so I could easily wipe it up if it happened again. I started to notice some antifreeze accumulating on the floor after I ran it. So, I figured that I needed to replace the heater core.

While I had the core out, I figured I may as well change out the blower motor which was a bit noisy... so I removed that as well.

So, now every thing is pretty well stripped that is related to the heater and ducts... I figured it would be a good time go on a venture to see if I can see any other issues while it was clear.

Sure enough, I could see a bit of light showing when I looked up the very corner of the passenger side... It was a spot that is not visible from the engine compartment, beneath the ledge and underneath the overlapping metal. About the size of a dime, in the firewall.

I wasn't about to start welding up there... it would have been a heck of a game of hit and miss. I took a caulk gun and filled it with silicon from the inside and outside.

I'm sure its an ugly glob, but no one will ever see it without ripping the car in half.
