leakdown test great success. 2 days later see trans oil on the ground? wtf?

[volcrano]

Did a leakdown the other day on a wore out motor to make sure the bottom was sealed before I split the top end. Motor held 6 psi for 90 minutes (I forgot while bullshitting). Never dropped a tad. No oil anywhere. Unhooked the tester and haven't really been in the garage. Went out today and noticed a puddle of trans oil at the back, where the case vent it so I suspect it's coming out of there. How did it pass a leakdown so long, but I have oil coming out? It seems that pressure had to have been in there for a while, but none of that makes any sense at all.I mean I flipped it on the grab bar and put it in the air on the stand, but I really don't see all that oil filling up the vent hose in that amount of time, few minutes maybe. It looks like maybe 1/4-1/2 cup came out. It's hard to gauge since it is oil. Maybe a 12"×3" puddle. Any suggestions? ?

Normal.

What is the normal part?

Leak down doesnt pressurize the trans area.

[volcrano]

Right. Unless there is a crank seal leak. But it held pressure so obviously that's not it. So why the trans oil 2 days later?

Because you tilted it up on the grab bar.

Sounds normal to me. Crank case and trans area are separate. The trans has a vent right on the back and if you stand it up or over fill it, it will puke immediately. About as fast as you can tip a cup over.

Ok, I'll consider it cool then. I never noticed it before, I've put alot of bikes on the stand. Thanks.

Clean it and see where it coming from. Is all you can do.

Depends on machine and where and how vent is run
