I am starting to think it might be the plastic bushings as they are old and maybe they are being pulled out of shape after the tension from the spring and everything once back together

There are your problems.
Change the piston head to a bearing one. The stock head uses a large (1/2") metal spacer as a nut to hold the head in place. An upgraded piston head with bearing is about half that.
When you upgrade any gun, the VERY FIRST part to be changed is the nylon bushings. You can't shim a gun properly with theses. And if your gun shot more than about 10 000 BBs, the gear axles won't be aligned properly anymore. You can't do any kind of decent shim job in that case.
