You can also remove the cap to get access to the oil separator. Knock the cap off from the inside with a wood dowel and a hammer, it's just crimped on. Use a little gum-pucky to seal it up when you're finished. This is less scary than burning it, which I have done with a torch and a rosebud. That makes a lot of nasty smoke that's bad to breathe. If you're burning brush this spring you could add it to your burn pile but that's hard on the paint.
