My final drive was closed up with high temp (red) RTV. Yes, that is the wrong stuff and no it wasn't done well enough to work keep it from leaking.

I looked up and brought in the gasket. The McCord (now Cooper-Payne/Federal-Mogul) is not in anybody's catalog. So, I opted for Fel-Pro (also now owned by Federal-Mogul).

The part I used to supply had a coined (the gasket material pre-compressed locally) slot that went up to the little vent hole in the top of the pan edge. For reasons I will not go into, we (I was at McCord then) had difficulty maintaining this feature in spec. This vent is kind of important so lube will not get forced out through joints and seals. The supplied part will have no issue this way as the feature has been eliminated.

So, If you can't get your final drive to stay dry, it may be no fault of yours.

Matt,
I am interpreting your message to read as though the Fel-Pro gasket is
incorrectly vented. If this is so, what are your suggestions to correct the
fault?
 Thanks,
Les Burt

Matt,

I am making the assumption from what you've written below vis-à-vis how it
vents that you have a 3.07 final drive (the 3.21 uses a different vent
system). If so there is another vent area. The two holes at 12:00 in the
large seal on the side of the final drive that faces away from the oil pan.

I've had nothing but good luck with the semi-aerosol Right Stuff sealant. I guess you could try sealing up something non-auto related first to prove it to yourself, but I have been amazed at how well it works.

I also have used it on a very stubborn none stock valve cover leak on our 50

It works!
No more leaks

All,
Some of the Felpro gaskets for the final drive that I have bought in the last several years have been assembled incorrectly. The venting holes do not line up correctly. It is just a matter of taking the staples out swapping the order so they align on the cover vent holes. The gasket with vent path should be to the cover side and the uncut gasket to the drive side. Both of my final drive also have a metal vent cover tab that fits on the outside of the cover and is held on by the adjacent bolts. Just what I have seen in the last few years.

Les,

My first suggestion is try to locate a part that has the correct features for venting. I don't know who else to try, but I will be looking around in the future.

If I find one, I'll get Bdub to put it in the book.

What I did ?
I very carefully formed a piece if 1/16 welding wire and bashed into the gasket surface in the hope of creating the desired leak.

Rob,

Yes, it is a 3.07 and there is still the hole in the pan rail and the cover plate with wings. As the original vent was there, I did not look for another, but I will before the final drive gets lifted in.

This (RDS55034) was a single layer - rule die cut piece. If the multi-layered part is still available, I couldn't get it come up in any of the listings.

Gene,

What is now Fel-Pro is supposed to still be running a from most of my old tooling. We used a matched metal prog die and made a part that was superior two the stapled layers. I guess the bean counters decided it wasn't worth their cost to keep the good tooling.

If it leaks again, I'm going to have to try the Dana part.

J.R. The felpro gasket now supplied as a replacement gasket for the
3:07 final drive is an assembled pair of gaskets that are stapled together.
One gasket that faces the final drive has a labrinth passage that goes from
the gearcase up to the vicinity of the vent hole in the cover. The second
gasket has no passage. There have been some different sheet metal stamped
covers used through the years and the small vent hole is not in the same
place on all of them. Gaskets are furnished without the vent hole punched in
the gasket towards the cover. After the cover and gaskets are assembled with
the labyrinth towards the gearbox, take a drill bit that matches the vent
hole in the cover and holding it in your fingers, gently drill a hole
through the gasket. This allows a channel for the air that expands &
contracts to escape or breathe without loosing any of the lubricant. Just be
sure to put the cover tab on the top bolt when you are finished as this
keeps dirt out of the hole. Hope this helps clarify this issue. I can post
pix if it will help.

Yes, I did and the Fel-Pro part RDS55034 is now a single thick layer WITH NO VENT FEATURE AT ALL...

The last time I saw the Dana part, it just had a slot in the gasket.

Fel-Pro was supplying the part (RDS55034) from MY TOOLING that I developed at McCord because it was much better than their stapled together pieces.

They are now supplying a rule die cut POS that I hope I made work.

Fel Pro came out with a new one piece gasket. It does not work at all.
I called and told them then or the problem,but will take some time.
We have another brand that will work along with the correct seal for
the left side with 2 small vent holes.

My final drive was closed up with high temp (red) RTV. Yes, that is the wrong stuff and no it wasn't done well enough to work keep it from leaking.

I looked up and brought in the gasket. The McCord (now Cooper-Payne/Federal-Mogul) is not in anybody's catalog. So, I opted for Fel-Pro (also now owned by Federal-Mogul).

The part I used to supply had a coined (the gasket material pre-compressed locally) slot that went up to the little vent hole in the top of the pan edge. For reasons I will not go into, we (I was at McCord then) had difficulty maintaining this feature in spec. This vent is kind of important so lube will not get forced out through joints and seals. The supplied part will have no issue this way as the feature has been eliminated.

So, If you can't get your final drive to stay dry, it may be no fault of yours.

Matt we didn't want to wait for a gasket so fabbed in a vent in the cover. It's offset so the gear doesn't throw oil out. Pic here

Wally,

You seem to have company at that.
Maybe somebody could do a simple kit.
Maybe somebody at Federal Mogul/Fel-Pro will read the note (just short of being a nasty-gram) and get back to me.
JimK says he contacted them as well, but I bet that there are still people there remember me.
We'll see.

Matt
