It could either be that some of the nuts ont the head studs came loose, in which case you could just clean up the head and retorque them. OTOH, the stud could also be pulling out of the case. Test this by installing the head and torque the studs to 5 ft-lbs over the spec JUST AS A TEST. DO NOT ASSEMBLE AND PUT THE ENGINE INTO OPERATION IN THIS CONDITION. The reason is that the studs will get even tighten as the engine warms up and this would certainly strip the threads out of the case. If you have studs that are stripped, the only fix is to completely strip down the engine and send it off to have threaded inserts (case savers) installed in it. This is a permanent fix. > Second, when I pulled the valve covers off there was a lot of little > gold flecks on the rockers and in the covers. Where does that > come from? Not sure. The valve guides are yellow brass and there is a layer of copper in the rod bearings. Grab the top ends of the valves and see if one of them has a lot of side to side slop (try side to side and up and down.) Compare all of them to see if one is bad. None of them should have perceptable play in any direction. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
