The Rotella Synthetic works well and I never hear lifter noise. I do have small leaks around the valve cover and rear intake seal. No crank seal leaks. I know that from having the flywheel ring gear replaced last year.
Would it be accurate to state at running higher pressures you would have greater leaks? It seams like a double edged sword. If you run a lighter oil it would thin out when warmer. That would seem to make it more prone to leaking. If a heavier oil is used, it seems that pressures would be higher. Is it just me or wouldn't you want something in the middle? Not trying to start a conflict here. As a novice on this subject, I just trying to think if its worth trying something different.

Phil,
I had asked that question of my mechanic last year, wondering if running a heavier
oil at higher pressures could lead to gasket failure and his take was that our engines do not produce enough pressure to blow a gasket out that was properly sealed. He runs 1200 hp in his drag race car and has not had an issue with too much oil pressure. I imagine there are downsides, as everything tends to be double edged.
Run what works in you engine and only consider a change if problems start.
