I'd suggest some ATF in each cyl, run the pistons up and down to coat everything. Then turn the engine til it just runs into the tight spot and check all the valves to see if there is one which has lagged behind its lifter, leaving a large valve lash. If so, spray it with some kind of penetrating oil to see if you can get some lubrication up inside the valve guide to free it up. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
