What oil filter and what weight oil are you using. These two items have a definite effect on the classic "Vanagon Clattering Lifter Syndrome". If you have not done so, change the oil to a 20W50 wt oil or to Mobil I 15W50 synthetic. Also install a new Mann or Mahle oil filter at the same time. This may well eliminate the clattering problem. If not, then you may very well have a mechanical problem beyond the "syndrome".
