I'm going thru the engine on my '70 MGB. I've got it out of the car and mostly apart, but I can't get the %*(%^& distributor out. I've got the bolts out and all that, but it's real hard to turn and I can't even start to get it to lift out of the block. Must be a bunch of crud down inside around the housing. I tried a WD-40 soak for a few days but no progress. Any old indian tricks out there?
