I was able to test...a did have just a few small bubbles come out at the seal at about 8 psi...I couldn't get a real good leakdown test for time as I did have another leak but was able to hold pressure constant at 8 psi and did notice just a few small bubbles at pto seal....is any acceptable at all? Or should there be none...would same it is why I have a little oil weeping out. Thanks
