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.

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!

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.

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 pile

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

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.

by JtownJoeHi, 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?

by AyyyI'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...-

How close should I trim a front rope seal? I usually use one piece seals.

by plyforWe used the new teflon type rope seals on a new motor with about 100 miles on it. Nice drip which runs down the oil pan front and no leaks elsewhere. It was put in according to all posted info. and greased very slightly. The leak is blackish oil. Is this normal with this type of seal. We ran out of the old style rope and the 2 piece pulley looks ok. Any suggestions ?...

I discovered when replacing a carb. that the gas shutoff valve leaks a little after it is closed so I am replacing it. I have the old valve off and after a little flushing to clean out the pipe I've installed the new grommet and am ready to put on the new valve. Question. How much need is there to hold/support the tank outlet pipe when tightening the...-

by HoogahMy ‘29 motor is at the engine rebuilders after discovering white metal in the sump when chasing a rear main oil leak (see separate thread “Dropped sump, found metal”). He’s going to re-pour the main bearings, but is happy with the condition of the babbit on the con rods (the motor has been rebuilt once that I know of). The babbit on the rear main was mostly gone and what was there looked way...
