Okay guys I know this may be viewed as a dumb butt question, but how do you remove the draft tube from the engine. The only reference my manual makes to it is that it should be removed and cleaned. I getting ready to send block to shop for prep. I was under the imprssion that it just pushed into hole and the bracket bolt at the oil pan held in place (I have removed the bolt). I have soaked the crap out it with rust remover -- it stil doesn't budge. PLEASE HELP. Thanks
