Can expandable Oil Return tubes be expanded too far?
 

First I want to thank everyone else here for thier threads concerning this topic. Without that information this would have been many levels of magnitude more painful.

I just finished replacing the aftmost oil return tubes (between cylinders 1&2 and 4&5).
Each was equally painful because I didn't want to remove the exhaust manifold. I'm a bit worried because the 4&5 tube expanded about a half mm further than the tube in the 1&2 did.
Here are my pictures:

Sorry, the tubes on a pie box, which explains the carmel rings under and around the tubes.

So far I haven't had any leaks (I got her up to operating temp and turned her around so I could re-park her in my garage, no leaks while engine ran or after so far), but I'd like to know what some of you here think about it.
Should I be concerned, or is this normal?

I don't think it is a concern.
I noticed some minor variation when installing mine.

No leaks so far!

Thanks, so far (about 10 hours after running the engine) its dry under my car.
This is the first time in since I got it.
