I'm tackling oil leaks one at a time and making good progress. My next step is to replace the oil return tubes. I just put the o-rings on with silicon grease and put the two ends together. Even on the workbench, it takes all my strength to move the two ends apart. There's no way they are going budge when they're under the car. They are ridiculously tight. I can tell a vice grip or hose clamp just won't do it.

Advice? Is there a more slippery grease I could have used? Why is there no specialty tool for this job? I'm going to invent one, I think.
