Well,,, In my slightly over a year on this forum, I have seen at least two instanceswhere "stuck" distributors were absolutely destroyed by their car owners in an attempt to time the vehicle or to extract the distributor from the engine..
Both of these cases resulted in long threads, and finally endedwith extreme measures taken to eventually and painfully remove the offending part!
I recommend patience..
I recommend a long term treatment of the distributor with all kinds of penetrating oil, perhaps weeks or even months prior to getting aggressive..
Take your time!!!
A problem like this has a way of "bugging" people to the point of obsessing on the removal of the distributor even though there is no real good reason to be in a hurry to get it out, or to even move it... resist the temptation to rush!
