Volvo AQ131D with 275 outdrive:<br />Don S had mentioned that sometimes you gotta jam a screwdriver up in the hole to clean out the plug.<br /><br />So I went out and unscrewed the plug and of course nothing came out.<br /><br />I didn't have a screwdriver but my post office box key worked good.<br /><br />But I did not get rust, I got pure black soot, clean soot.......no rust whatsoever.<br /><br />The water that came out, about 1 pint (Unplug your manifolds!) was clean......<br /><br /> <br />What's this sound like? I'm still going to replace the manifold this winter, and with the compression check I've hopefully ensured no damage has come to cylinder #4 through corrosion....<br /><br /><br />Anyway is this a good sign? I'm thinking it was running rich or something or maybe the previous owner just never took it out.....or maybe he did and that's why it's clean.<br /><br /><br />That was a lot of water that came out - thanks guys - I would not have known to do that!
