i know this isnt the place for it but i get no response anywhere else. i am restoring a 78 302 in an F150
it runs but has a bad hesitation off the line
i put a timing light on it and it is 16 degrees advanced. supposed to be 6 but the distrbutor is frozen to the block. any clues on how to make it release without brute force?

 

Mario,
I have had this problem before. The oil swells the O-ring and siezes the distributor into the block. The trick is not to damage anything else while removing the distributor.
Assumption: The distributor is a total loss at this point. You are going to have to destroy the distributor to remove it. I had to use a 4 ft. pry bar to get mine out and the distributor was cracked severly by the time I got it to budge. Go buy a new distributor. They will want a core and will accept the destroyed one as a core. Use blocks of wood to protect the fulcrum points as you pry the distributor out. It isn't going to be pretty.
Good luck,
KingFisher

 

well it is running now i think it will live till it dies then i will break it i guess.

 

I soaked the distributor at the block daily for a couple days with PB Blaster. Then with clamp loose; I placed block of wood block on the vacuum advance and smacked it (wood) with hammer. It broke loose and no damage to advance. But a vacuum advance module is cheaper at an auto parts store than the whole distrubutor. Be patient and keep working at it firmly; but not wildly. Good luck!
