    Valve cover breather cap?

    It occurs to me that I have never cleaned out the breather cap. Looks like wire mesh of some sort. What's the best way to clean it out...soak in solvent?

    I think the book does say to rinse it in gasoline but I don't see why most solvents wouldn't do as well. Tom

    Nothing wrong with using high-test gasoline for cleaning...or is there?!?

    Some solvent residue will cause damage if breather isn't totally dry. Fuel is fine, drys quick.

    Probably not since they took the lead out. There was a time when it was so commonly used that mechanics were getting lead poisoning. I quit using it 50 years ago and find odorless mineral spirits a more pleasant and perhaps safer substitute. Granted it doesn't dry as quickly but I don't see that as a problem.
