Did you tape the end of the crank when you put it in? The threads can rip across the the seal and cause a future leak.
I am guessing you have hydro becasuse you tried both seals. I noticed a small leak on one of my quads a long time ago and as it turns out the flywheel wasn't touching the seal to keep it seated all the way. I made a washer that fit in there properly and it worked great, no more leak. Is your seal working its way out just enough to leak?

A little seepage doesnt hurt anything either.Often after 3 or 4 months I take cover of and there will be a mix of oil,water crud about a 1/8in. up.

I thought the spacer ring that lines up stator also holds seal in place.The last 2 seals i put in, 1 was a 5mm, and 1 was a 7mm,looked fine, except a little damage from removing it.My main question was, does the seal fit tight enough around the shaft.I have noticed that the seals do not leave a mark on the crank where they have been running,with a spring loaded seal,it shouldnt leak.I wondered if a slightly tighter seal would help,if there is one that will work?I just wanted to run this thru the R and D to see what you all think?

You may have a crack in your case . Are you putting a light coating of sealer on the seal bore ? Pressure test the case before you pull the seal out and see exactly where it is leaking.
Best i can tell it is coming out around crankshaft itself.I put hondabond 4 around outer part of seal.What all would i have to block off to pressure test?

Its the same as on the bench testing. Oil inlet,scavange outlet,valve cover vent,starter clutch vent. ONLY use 5 to 10psi regulated air.
I pressure tested it,you were rt,hairline crack running out from hole in case for seal at about 3 0clock,TOAST!!!!!!!!!! Probably from earlier crank bearing failure
