I finally decided to install the Crane optical unit on the car. While I'm in there (Hi DW!) I would like to clean and lube the disitributor. Can I dunk the whole thing, minus the trigger points and vac can of course, in some cleaning solution, or is there something in there that I'll screw up. I also have a tube of Bosch dizzy grease so I won't be putting junk on the breaker plates.
