I need to get my oil pump drive spacer off, and it is like hanging off by like half an inch but will not come the rest of the way off....I know they are supposed to slide off but mine wont. The only reason it got as far as it is is because of a lot of prying and pb blaster and lube and sanding the surface smooth. I was just wondering if anyone has any tips or tricks on getting these off when they are stuck like this?? any help is appreciated!
