Hey guys!
So I recently got a Pentax 6x7 MLU and I’ve been having some issues with what appears to be a slight light leak going diagonally across the edge of the frame in some images. It only happens on maybe 3 out of 10 frames per roll and sometimes less. Sometimes when I’m holding the camera in portrait and some not, but always in the same spot on the negative.
I figure it isn’t coming from the back door because there are no light leaks outside of the frame on the negatives too. I just replaced the light seals around the ttl prism, but they still appear sometimes. I’m hoping someone else has had this issue and can give me some advice! Thanks for the help! I’ll post some images with the issue

Is it the top right corner in the images? If so, I can see it in the first one, but not the second.

Look above the chimney on the right, most visible below the power line.


Would need to see more and the full uncropped frames, ideally as proper contact sheet(s). We don't know the time duration that a frame sits between spools or light conditions.
