With my work light in the engine compartment, inside the car I checked the firewall for "leaks". I was surprised to see lots of light along the seam where the firewall bolts together. Is there a factory seal missing? With everything together, I imagine it will be difficult to insert a seal. Perhaps a careful application of silicone caulk?

I use double sided friction tape and use a machinists rule to make sure both mating surfaces are reasonably flat.

originally there was NO seal, remember these were all new parts and fit together perfectly. nothing was used back at the factory and i don't recall hearing of any complaints on squeaks, I would as rowdy says use today friction tape when ever metal hits metal to avoid anything...Originally posted by slammin View PostIll., Region MARC & MAFCA

Ya know, I was thinking about the same thing the other day and wondered to myself, why not use Gorilla tape across the inside seam. Should work well as that stuff hooks up better than the duct tape. Just needs a bit of cleaning first to be sure it has a clean surface.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!Comment

Friction tape would be used IF he was going to dis-assemble the two halves, I would think the gorilla tape on the inside flat where it can't be seen. JMO

Since the car is painted and assembled, short of a clear caulk, I won't be putting anything between the joint. I need something almost invisible. I'll look into Gorilla tape. I hope they make something close to Vagabond green.Comment

Gorilla tape is pretty strong stuff and it make take your paint off when removing it. How about a little thin strip of dumb-dumb inside? This can be pressed into the crack and wiped clean afterwards you wont even see it.
Just a couple more thoughts to throw on the pile3~ Tudor's & 1~ Coupe

I was going to post the dum-dum idea also. If I did anything, that's what I'd use. I never drive my cars in the cold weather, so I wouldn't worry about a small opening. Our roads are already white with road salt, so no more old car driving for the next 6 to 7 months.Comment

It's DUM-DUM & at any body shop supplier & maybe even at NAPA. Cars couldn't exist, without DUM-DUM! It's fun to stuff your blow gun with it & shoot it at the wall. We used to have DUM-DUM "WARS"--LOL

Menards has a similar putty in the electrical department. It's used to seal the holes where wires enter a wall or box.Originally posted by Mark Maron View Post
I think auto parts stores sell a 3M product that comes in long thin strips.
In the 70's I installed several aftermarket A/C units in cars, and a handful of dum-dum always was included in the kit.Comment

I purchased the McBee A-8926902 rear seal for the Detroit with Teflon. It comes with a plastic sleeve and am not sure of its purpose.
Is the sleeve used in a new installations or is it for shafts that have a grove warn into it? If you do use the sleeve, how is it installed?01-13-2022, 03:11 PM -
Has any one had good luck with the one pice rear main seal ? Like 100% success.01-20-2018, 09:56 AM -
Got call a from the Model A shop. They informed me progress of my A, rebuilt motor and lots of other things are basically done. So now once weather gets warmer, I will be going there to drive it around for a couple of hours as shake down so they can correct any concerns I may have before taking it home. They informed me that a rope seal had a little seepage, but since it has been so cold they have...03-03-2019, 09:04 AM -
Hi, I have the new modern seal and there is an inner ring that appears to be directional, does the beveled side inner seal fin point toward the radiator or toward the crank case?10-24-2017, 07:18 PM -
Just got a new "Repeal" license plate topper from Synder's. The face of the topper is a paper sticker on a nicely painted metal frame. I am wanting to seal the paper face with clear lacquer or polyurethane but don't know what to use as I don't want to crinkle up the existing paint or paper. Have any of you done this and if so, what did you use? Now I'll admit this is not as technical...12-14-2022, 09:06 AM -
I figured out the seal but which way does the bushing go in? Dimple towards the front or rear?02-16-2019, 02:15 PM -
I'm installing rear wheel hub seals right now and I have a question. I searched the Chassis and Powertrain tech areas, but no luck. Maybe I'm too stupid to do an efficient search??
How deep do the seals sit?
Seams simple enough... most cars have a ridge to seat the seal against, but not in this case. This makes for no hard stop for the seal and I'm concerned that I'll install the...05-23-2018, 06:49 PM -
The threads were badly worn on my right front spindle. I got a very nice original from Steve at Bert's. I just finished getting it all back together. But, the inner dust seal (cupped washer) which is a nice press fit on my old spindle, spins freely on the new spindle. Would a small amount of JB Weld on the inner diameter/back of the seal work to hold it in place?06-16-2020, 06:15 PM -

I’m trying to get the details together for my windshield for when it’s painted and ready to assemble. I bought the outer seal from one of the vendors in the past and I can’t decide which way it goes on. Maybe I need to get some from somewhere else that is correct. A couple pictures included and it looks like I need to bend the metal strip to tighten the seal beings it nearly falls out. So which...06-07-2020, 11:29 AM
