I don't think there's any difference in size of the tubes, but yes, being plugged is likely if it gets pushed out - OTOH, RTV is not a glue, especially as you'd have a real hard time getting the metal surfaces clean enough for it to stick, might be better off using some thin shim stock to tighten it up after you clean it well - it should be a very tight press fit, most folks have a hard time getting them out
but if you've got that much pressure in the pan and are getting that much oil out the road draft, I'd say you've got a blowby problem
