The Permatex anaerobic gasket maker never set up except where exposed to the air. It appears to have washed out where the bearing cap meets the block.
Anaerobic only cures in small spaces when exposed to metal and not air, don't know what happened but if you had any gap to seal anaerobic probably wont work. Beyond 0.015-0.02" it wont ever cure depending on who you trust. It's worth reading up on what it's used for and why, at least I thought it was. Hopefully it works this time.

Because the squeeze out cured is why I think the anaerobic rtv formulation might have been wrong.

This tire lost 1psi in 24 hours.

Looks like I've been a little harder on these rims than I thought...

not that horrible, could you donk it back to shape and save it?

It doesn't have runout (aside from the indent) so probably donkable. I'm going to be taking it on a test drive on Sunday to see if the leak increases while driving... If not, I'll have on board air to fill every morning of the trip.

are you running regular air or nitrogen? this little adventure might be right for some nitrogen maybe less fluctuation between day and night running temps or less of a possibility of pressure loss in the stored wheel..

That's a good idea. I've got a tank for shocks anyway that I'll use.

i'll take my lashing then............ care to elaborate?

All gases that we encounter in the pressures used in tires respond exactly the same way according to Boyle's Law. For a given volume of gas, the pressure will increase the exact same amount per X amount of rise in temperature.

Harry did a nice series of tests by using a pair of jars connected to each other with back to back lids with purge valves so he could fill one side with Oxygen and the other with Co2. Separating them was the finger from a latex glove to show which side had the most pressure at different temps from out in the hot sun to in the freezer. All managed to stay exactly the same. The nitrogen gas tire fill industry is full of nothing but lies.

Do a little test for us. Record the ambient temperature the next time you check the tire pressure. Then check it when it is the coolest part of the day, (right after sunrise) and then the warmest part. You'll likely encounter more than a 1 psi temp swing.

I will.

The first 2 recordings for the front right tire (other tires had no change). Since it's a climate controlled garage... 65F both times.

Aug 4 - filled to 26psi (I forget the starting psi but I had just filled it a few days before).
Aug 5 - 25psi filled to 26psi.

What's the current phase of the moon?

ok.........i thought i read the molecules are bigger and therefore don't permeate materials at the rate air does. or pump in moisture if you don't run an FR.

so all these nitro filled shocks are just a purity thing for the internal sys then basically?

Air is 78% nitrogen so you’re only varying the remainder which is 21% oxygen and then some argon and such.
