Good morning to all,
I've been using the Permatex " Right Stuff " for a couple of years now.
The engine in my Suburban I recently went over the valve adjustment and found a couple of wet area's on the valve cover gaskets - I cleaned and used the Right Stuff on them and that oil leak is solved. No more oil smell while sitting in traffic. I use that on all my small block and big block china walls - zero leaks. It dries quick enough while dyno testing as well. I also use the Permatex Grey silicone with great success as long as you have time for it to properly cure. Make sure the surfaces are CLEAN and OIL FREE.
I found that to be very important in the curing process.
I hope that helps.

Respectfully,
