Oil Pan Leak After Synthetic Oil

[landtoy80]

I had no oil leaks when I got my Supra 6000 mi ago.
I switched to RotellaT syn 5w40 and now have a leak at the front arch of the oil pan. The rear of the pan under the rear main is starting to leak.

I had several seeps and a flowing arch leak on my Land Cruiser before I changed to RotellaT syn. A couple of oil changed later they all stopped leaking.
I hope this will happen to the Supra.
Anyone ever see this?

yep, on 2000 grand prix gt. ran conv. oil for 60k or so switched to synthetic and bam oil leak. I guess what happens synthetic "cleans" or removes the "gunk" causing leaks where the conv. had build up and pluged the leak. So there never really is a leak, untell the gunk isnt there any more.
Hope this makes sence.
