I suppose it's even possible that something happened to this case/engine from the outside. You will want to weigh the rods and make sure they are a matched set; if they aren't, get a matched set to balance. If the case has been align bored 1 mm or more oversize, then you will not be able to buy main bearing sets that include the steel backed #2 main bearing halves. They won't be as strong. Clean the case up and bolt the halves together around the outer edges, then reach in to the #2 main bearing saddle with a .004 feeler gauge and check to see if there is a gap there between the case halves. If there is, this case may be deformed. I agree with Berg that shuffle pins are only a band-aid. Don't go that route. If you use a counterweighted crank and balanced parts, and set the end play correctly, you won't need them. The left side of the rear mount crossbar is a good place to mount the full flow oil filter. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
