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


Recommended Posts

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? ?

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?

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