I just installed a valair dd clutch and the hydraulic system and i replaced the rear seal where the drive line goes into the back of the transmission. After driving about 20 miles it started leaking real bad so i changed it again. About 50 miles it started leaking again but this time much worse. What is going wrong??? :banghead:

Compare the orginal seal to what you are putting in. Are they equal?
Did you destroy the coil inside the seal lip?
Is there a bad groove or scoring of sliding yoke on outside?
Is the plug in front of U-joint the leak?
Are you destroying the seal during istallation?
Is bushing in extension worn out?
One or more of above is probablly your issue. JMHO

Maybe your yoke is bad?
