Regular grease is quite useless. Use copper grease. I can guarantee you it will never get stuck or your money back.Just needs regular grease. every time they are removed and refitted, always use grease, or next time will be the nightmare.
If the ties work, don't see why you need to use screws. Cut down on oil changes, then you won't have to worry about the 2 hours. I do 5 hour oil change every 10 years. The cars purr like champs.front screws had all gone, replaced by cable ties. It took me nearly two hours to change the bloody oil!
