This rusty ‘78 440 Pursuit engine was soaked in the infamous molasses mix for a few months last year and a few parts came off easily. But then the removal of the camshaft was more difficult as expected. Actually after spraying Aerokroil on the camshaft bearing for like a month and removing the rear plug the camshaft was persuaded to move with a heavy hammer and now moves easily.
Now for the Pushrod.
Unfortunately after using Aerokroil for many months that pushrod will not budge even after using a vice grip, no turning, even after banging on the tip of the pushrod with a hammer and punch, not even with banging the camshaft into it as the camshaft is moved back and forth can free it.
My next thought is to use a torch to heat up the block but not too much. If the pushrod area is heated up and the rod does break free would it be advisable to then spray water on the block to cool it down? Should I heat up just the pushrod, which would expand it or just the block which then a vice grip would be attached and ready to attempt to turn the rod?
Oh, and the lifters were also soaked with Aerokroil and they all have been pushed up and out of the way of the camshaft.
