I think the paper gasket is much thicker than the end play spec, so adding it probably put you probably twice as high as you should have been, in end play. I'm not sure what the down side of too much end play might be. I expect excessive wear might be one of them. Think of what the rod bearings must go thru to stay in line with the pistons if the crank can move back and forth too much. Some of the sounds sound like the screws that hold the fan housing to the case, so you may be pulling the fan housing off to check those. If you do this you can measure the end play from that end, which works just as well. I don't think centering the fan housing is that big a deal, but if you're way off the oil return thread on the fan hub will grind off alum from the fan housing and pull it into the case. I think this is unlikely. It's not likely to cause the fan to rub, and the case will expand more than the crank in any case. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
