Hey Matt,

I run into this on my RS every rebuild.

Here is how I manage it.

1. I use a VERY light layer of assembly grease to help produce a better seal.

2. I torque the bolts down to to below the toque settings, and then get the leak down on it letting it leak. I slowely by hand tighten the bolts in a star pattern until the seal is good.

Thanks
