Nope. None. As Tugly stated, that issue was corrected long ago in changes in formulations and o-ring compounds, 1960-70's I believe, but the issue lives in the collective memory.
Now, I did have a leak on the passenger side due to a valve cover bolt being loose.
I am the only one that works on this truck. Go figure....
I hate the passenger side bottom VC bolts with a passion.

When I first got my PSD over 7 years ago, it had 124k miles and would romp as warm as 65F-68F. I ran Delo 400 15w40. Once I switched to 5w40 synthetic it has never romped since. Some of the additional cost is offset by longer oil change intervals. Also, no leaks. I think the whole notion with synthetic oil leaking more, or creating leaks, is largely a myth. Especially with modern engines and synthetic gasket materials.

Yep! And some think that it is still a new technology and hence not reliable. However, synthetics have been around for about 80 years. The Germans relied on synthetics for about 50% of their needs at times during WWII.

When it romps, I found that mashing on the accelerator briefly, than letting go, makes the romps go away, even with 15W40 oil (but this accelerator snap trick has not been tested below 20 degrees F).
When I switched to synthetic 5W40, I never had the opportunity to practice snapping the accelerator to make the romps go away again. Because the romps never appeared with synthetic. Just like the others have reported.

Two things: Fender well and 13mm flex socket. You can get at those bottom buggers in the rear (closer to the firewall) quite easily through the fender well with a 13mm ratcheting combination wrench. I use a 13mm flex socket on my Milwaukee driver drill with crazy-long extensions from the top. I can get every bolt on the VC with the driver, but I have to switch to a deep socket with a universal on those stud bolts.
Synthetic oil causing leaks isn't a myth, it's a part of history. While not disputing jhl3, I thought it was in the 1980s. Once a product as fundamental as oil starts making expensive damage to a car, that reputation is hard to kill - even decades later.
The extended oil change only holds IF the oil stays golden. With our high-mile engines, it's very easy for soot to get into the oil, through a variety of channels. I have exhaust getting into the oil via the valve guides - I can actually see it. I can't even get my 3000 miles out of the oil before it turns black, so I had to install an oil bypass filter. My synthetic should make it 5000-6000 miles now... if I choose.

Rich, I cannot read the manufacturer of the socket from the picture. Could you help me a bit? Is it SnapOn? I have a set of the floppy headed ones. This may work better.

Snap-On has them - I bought Armstrong. They don't flop around (yet), so you can "aim" them when approaching the bolt. They are specifically designed for the battery-powered impact drivers that everybody buys now. Don't forget the impact extension set:

After reading the specs on each oil, the T5 doesn't mention diesel motors at all. Says heavy duty but not diesel. The T6 mentions Diesel engines several times in the product description. Interesting

The viscosity of the oil when cold is what helps or hinders the injectors. The "5" in the 5/40 is what makes all of the difference. Effectively, it is a 5w oil until it begins to warm up and it slowly becomes a 40W as it continues to reach FOT.
A "10" W would obviously bridge the gap, but it might be "close and yet no cigar".
I would try the 5/40 T6 for this winter at a minimum. You may find you'll run it all the time. The injectors in this 7.3 are noticeably quieter with the 5/40.
