Default Sealing the front engine cover

[color=left=#333333]I have the front cover off my 350z to replace the oil galley gaskets. The galley work is complete now I need to use Permatex Ultra Grey to seal the front cover and lower pan. My question is should I torque to full torque immediately or finger tight and let sit for 24 hours then do the final torque?[/color]

I would just follow the manufacturers recommendation: Permatex Website

"Apply a continuous, even bead of silicone to one surface, surrounding all bolt holes. Assemble parts immediately while silicone is still wet. Finger tighten until material begins to squeeze out around flange. Allow to dry for one hour then retighten 1/4 to 1/2 turn."
"Silicone will skin over in one hour and fully cure in 24 hours under normal conditions. Allow more time for cold or very dry conditions"

On the quoted 'retighten' part, I would then tighten the bolts to the correct torque spec.

Thanks, that is what I will do.

Followed the instructions to tighten after one hour. Engine is back together let it cure for 48 hrs. Ran it today, no leaks!
