Frustrating Oil Leak

Try installing a PCV Valve. Relieving the pressure inside the engine might effect the oil leak. My 59 A/B leaks not! I installed a full-circle lip-seal on the front of the crank and a PVC tappled into the underside of the intake manifold. The PCV was from an early Mustang 6 cylinder and has pipe treads on one end, so it screws right into place. No hoses!
I use fluid grease, NLGI #000 with MoS2 (Moly) in the gearbox and steering gearbox, and they don't leak either.

An oil leak coming out of the slot at the bottom of the bell housing could also mean your trans front seal is worn as I found out when I swapped a 3 speed for an overdrive unit.
 
It has been so long since I made this post that I forgot what I did to solve the problem. I looked through my records and found a receipt for an oil pump drive cover from Baxter Ford Parts. Then I looked back at my engine photos and saw the culprit--a brass screw extending beyond the engine surface so that the old cover could not seal the area and was warped in the process of tightening. I filed off the extruding screw head, inserted the gasket and new cover and "presto" no more leaks (well maybe a couple of drops once in awhile). I hope my pictures come through!

if you use a new modern oil seal expect a oil leak. the new seals are junk find an original seal. those new seals are wimpy & soft.the old style contain asbestos the new don't contain asbestos don't worry you won't die if you touch it
 
The PVC advice is spot on. I welded up the 59A style pan breather with a pipe plug, and routed that opening to a PVC- No more leaks- Negative crankcase pressure!. Newc
 
Is all this oil leaking causing clutch problems. Oil getting on the clutch disk. I am having clutch problems. As soon as I ease off the clutch pedal car starts shaking.
I haven't had the car long. I am going to clean it up good and see if I can tell anything about where the oil on the motor is coming from. I have a new pilot bearing, clutch pressure plate and throw out bearing. I sure hope the main seal isn't bad. I haven't noticed any oil on the driveway to speak of.
I hear you have to pull the motor to change a rear main. I am not equipped for that.
 
when you replace the seal get an orignal one. those new seals are wipney junk . the new ones contain no abstoses. get an orignal you wount leak a drop .do you think ford could sell cars whith engs that wee pissing all over the floor the new seals are junk. i replace rear seals for t birds that just had the new crap leaking the orignal seale rope works that b.s of marking there spot is realeted to when cars had no real seal
