?? for the brain trust. Which sealer to use?

[wdfifteen]

I vaguely remember from when I rebuilt my 911 that I used these two sealers in specific locations. Of course I have no memory of which was which.

I effed up installing the generator stand on my '56 coupe and had an oil leak. Getting another gasket is going to be problematic (shipping costs more than the gasket) so my realistic options are to go to NAPA and get a sheet of gasket material and make a new one (PITA).
OR
Use some of this stuff. The data sheets seem to say they both do the same job, but Porsche wanted them used in particular areas of the 911 engine assembly,so there must be some difference.
Any guidance as to which one I should use? Or should I just bite the bullet and make a gasket?



I had the generator out half a dozen times chasing a charging problem and at some point I tore the gasket without realizing it.





The surfaces are flat and easy to clean.



Which do I use???

3 bond grey or permatex grey - https://www.permatex.com/products/gasketing/speciality-gasket-makers/permatex-motoseal-1-ultimate-gasket-maker-grey-2-7-oz/.

From the specs I would be confident 1211 would work.

TB1211 is ideal for places where a long, faultless seal is absolutely critical. Recommended for sealing flange surfaces, screw sections and as a gasket dressing, to prevent oil, water, gasoline and chemical leaks. Long tack-free time and fully cured in 24 hours. Recommended for all automotive, motorcycle, watercraft, snowmobile and ATV engines.

Norm, uh, Patrick, I'd use the "Gasket-Matic 4000" I have had great luck with it.

I got nothin'. Hot outside. Good luck!

Per Billy’s suggestion I went with the 1184.
I shoulda just put some oil additive in it - some of that Crankcase Stop Leak and Engine Rebuild in a Can stuff.
