Blowing Oil Out The Dipstick Of My 1976 F-150

I thought I would ask here, even though this doesn't apply to my Mustang. I bought a 1976 F-150 this august, and haven't driven it much, so I was suprised to notice such a bad oil leak. It sprayed all over my transmission, my exhaust pipe, and even all the way back on my rear tire.

Sounds like you have a lot of crankcase pressure. If you could vent that pressure off, the oil should stop coming out of it. If simple breathers won't help, you might need to look into a vacuum pump.

If Your Sure Its Coming From Dipstick . The Simplist Solution Is Your Pvc Valve . Caps Whatever In Your Valve Covers Isn't Letting Off The Pressure. Take Them Out Or Change To Different Kind

Could be excessive blowby past the rings that is pressurizing the crankcase. A compression test or better yet, a leakdown test will tell you a lot. It may be bad news, but at least you'll know it.
